The machine description files are all in `src/m', and have +names similar to, but not identical to, the machine names used in +configuration names. The operating system files are all in `src/s', +and are named similarly. See the `configure' script if you need to +know which configuration names use which machine and operating system +description files. + +If you add support for a new configuration, add a section to this +file, and then edit the `configure' script to tell it which +configuration name(s) should select your new machine description and +system description files. + + +Here are the configurations Emacs is intended to work with, with the +corresponding configuration names. You can postpend version numbers +to operating system names (i.e. sunos4.1) or architecture names (i.e. +hppa1.1). If you leave out the version number, the `configure' script +will configure Emacs for the latest version it knows about. + +Acorn RISCiX (arm-acorn-riscix1.2) + + Emacs 19.29 has changes that ought to support RISCiX 1.2. + + Due to a bug in the RISCiX C compiler (3.4.5), emacs must + be built with gcc (versions 2.5.8 onwards). + + In addition, you will need GNU sed and GNU make, as the RISCiX release + versions of these utilities cannot cope with building emacs-19! + + GNU sed should be configured with: + + env 'DEFS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \ + -Doptarg=gnu_optarg' ./configure + + GNU make (3.72+) should be configured with: + + env 'CFLAGS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \ + -Doptarg=gnu_optarg' ./configure + + Emacs may be configured to use the X toolkit, by adding --with-x-toolkit + to the configure command. If you do this, you will need to edit the line + in src/Makefile which defines LIBW (about line 59) to read: + + LIBW= -lXaw_n + + This ensures that the non-shared widget library is used. + + It is unlikely that this version of emacs will work with RISCiX 1.1. + +Alliant (fx80-alliant-bsd): + + 18.52 worked on system version 4. Previous Emacs versions were + known to work on previous system versions. + + If you are using older versions of their operating system, you may + need to edit `src/config.h' to use `m/alliant1.h' (on version 1) or + `m/alliant.h' (on versions 2 and 3). + +Alliant FX/2800 (i860-alliant-bsd) + + Known to work with 19.26 and OS version 2.2, compiler version 1.3. + +Alpha (DEC) running OSF/1 or GNU/Linux (alpha-dec-osf1, alpha-dec-linux-gnu) + + For OSF/1 (aka Digital Unix) version 4.0, update 386, + it is reported that you need to run configure this way: + + configure --x-includes=/usr/include --x-libraries=/usr/shlib + + For 4.0 revision 564, and 4.0A and 4.0B, Emacs 20 seems to work + with no special configuration options. However, if you use GCC as + your compiler, you will need version 2.8.1 or later, as older + versions fail to build with a message "Invalid dimension for the + charset-ID 160". + + Note that the X11 libraries on GNU/Linux systems for the Alpha are + said to have bugs that prevent Emacs from working with X (as of + November 1995). Recent releases work (July 2000). + +Altos 3068 (m68k-altos-sysv) + + 18.52 was said to work, provided you don't compile unexec.c with -O. + +Amdahl UTS (580-amdahl-sysv) + + Small changes for 18.38 were merged in 18.39. It is mostly + working, but at last report a bug sometimes causes Emacs to + grab very large amounts of memory. No fix or explanation + has yet been reported. It may be possible to find this bug + if you find which Emacs command it happens within and then + run that command with a breakpoint set at malloc. + + The 5.2u370 compiler is so brain damaged that it is not + even worth trying to use it. Success was obtained with the + uts native C compiler on uts version 5.2.5. + +Apollo running X Windows (m68k-apollo-bsd) + + Apollo version now supports dumping. It has been tested on SR10.3 and + SR10.4. It certainly requires at least SR10.0, and maybe SR10.2. Be sure + to build in the BSD environment. + + By default, everything is compiled with the switch "-W0,-opt,2". Don't try + to change this to full optimization (-O). The full optimizer (in Domain CC + 6.7, 6.8 and 6.9) generates some bad code in several modules which causes + the emacs window, under X, to be refreshed with each keystroke. + + The configuration stuff should work for the most part. However, some Domain + installations may have to edit src/Makefile manually after it is created. + There are too many versions of both cc and X to automate this easily. + + In `lib-src/Makefile', emacsclient and emacsserver compile and work fine + under CC 6.9. They now probably work under other versions of the compiler, + as well. + + The Apollo Domain CC compiler will issue quite a few warning messages, + mostly complaining about incompatible pointers. In general, these are + harmless and can be ignored. If you discover otherwise, please submit a bug + report identifying the problem in detail. + + When you try to dump emacs, you may get the message ".rwdi section needs + relocation." This means you are linking with some code that has compressed + data sections. In some cases this comes from linking with X libraries. Try + using shared X libraries instead. With some versions of Domain/OS this is + as simple as removing the "-lX11" from the LIBX line in src/Makefile. + + When running the configure script, use the configuration name + "m68k-apollo-bsd". You will also need to use the "-with-gcc=no" and + "-with-x" options. Depending upon your site configuration, you may have to + use other configure options, as well. Examine the INSTALL file for other + configure options. + + Check out the file 'lisp/x-apollo.el'. To use it, add + + (load "x-apollo") + + to your .emacs file. It provides useful default Apollo function key + bindings. + +AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv) + + Emacs will probably not work with certain kernel constants too small. + + In param.h CDLIMIT should be at least (1L << 12) in order to allow + processes to write up to 2 Mbyte files. This parameter is configurable + by normal means in /etc/master.d/kernel; examine that file for the + symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then + do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so + forth. + + In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively + to allow processes with total size of up to 2Mbytes. + However, I'm told it is unlikely this would fail to be true. + + The MAXMEM may also prevent Emacs from running. The file + 3B-MAXMEM in this directory explains how to increase MAXMEM. + + On some of these machines, you may need to define IN_SCCS_ID + in config.h to make Emacs work. Supposedly you can tell whether + this is necessary by checking something in /usr/include/sys/time.h; + we do not know precisely what. + +AT&T 7300 or 3b1 (m68k-att-sysv) + + 18.52 worked. If you have strange troubles with dumping + Emacs, delete the last few lines from `src/m/7300.h' and recompile. + These lines are supposed to produce a sharable executable. + + `src/m/7300.h' defines SHORTNAMES because operating system versions + older than 3.5 did not support long symbol names. Version 3.5 does + support them, so you can remove the #define SHORTNAMES in that + version. + +Bull DPX/2 models 2nn or 3nn (m68k-bull-sysv3) + + Minor fixes merged into 19.19, which should work with CC or GCC. + + You should compile with all the POSIX stuff: undef _SYSV and define + _POSIX_SOURCE, _XOPEN_SOURCE and _BULL_SOURCE. + + On bos2.00.45 there is a bug that makes the F_SETOWN fcntl + call enters in an infinite loop. F_SETOWN_BUG has been defined to avoid + calling it. + +Bull DPX/20 (rs6000-bull-bosx) + + Version 19 works. + +Bull sps7 (m68k-bull-sysv2) + + Changes partially merged in version 19, but some fixes are probably required. + +CCI 5/32, 6/32 + + See "Tahoe". + +Celerity (celerity-celerity-bsd4.2) + + Version 18.49 worked. This configuration name is a hack, because we + don't know the processor used by Celerities. If someone + who uses a Celerity could get in touch with us, we can teach + config.sub a better name for the configuration. + +Clipper (clipper-???) + + Version 19 has support for some brand of clipper system. If you + have successfully built Emacs 19 on some sort of clipper system, let + us know so we can flesh out this entry. + + Note that the Orion 105 is also a clipper, but some system-related + parameters are different. + +Convex (c1-convex-bsd, c2-convex-bsd, c32-convex-bsd, c34-convex-bsd, + c38-convex-bsd) + + Support updated and residual bugs fixed in 19.26. + +Cubix QBx/386 (i386-cubix-sysv) + + Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c + due to a compiler bug. + +Cydra 5 (cydra-cydrome-sysv) + + 18.51 worked in one version of their operating system but stopped + working in a newer version. This has not been fixed. + +Data General Aviion (m88k-dg-dgux) + + 19.23 works; however, the GCC provided with DGUX 5.4R3.00 fails to + compile src/emacs.c. GCC 2.5.8 does work. + The 19.26 pretest was reported to work; no word on which compiler. + System versions other than DGUX 5.4R3.00 have not been tested. + + DGUX 5.4R3.10 works with 19.29 and 19.30. + + DGUX R4.11 contains changes to the stdio internals and it doesn't work + with versions before 20.2 without patches. 20.2 works in interactive + mode but usually fails in batch mode. The problem is that using + stderr in the dumped emacs usually leads to a segmentation fault. + Only m88k has been tested. + +DECstation (mips-dec-ultrix or mips-dec-osf) + + This machine is the older Mips-based DECstation. + Emacs should now work on the Alpha CPU. + + 19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work + on Ultrix 4.2a and on 4.4. + + One user reported 19.25 did not work at all with --with-x-toolkit + using X11R5 patch level 10, but worked ok with X11R5 pl26. + + See under Ultrix for problems using X windows on Ultrix. + Note that this is a MIPS machine. + + For Ultrix versions 4.1 or earlier, you may need to define + SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems + to insist on defining malloc itself. + + For Ultrix versions prior to 4.0, you may need to delete + the definition of START_FILES from `src/m/pmax.h'. + +Motorola Delta 147 (m68k-motorola-sysv) + + The EMacs 19.26 pretest was reported to work. + + Motorola Delta boxes running System V/68 release 3. + Tested on 147 board with SVR3V7, no X and gcc. + Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc. + Reports say it works with X too. + + The installation script chooses the compiler itself. gnucc is + preferred. + +Motorola Delta 187 (m88k-motorola-sysv, + m88k-motorola-sysvr4, or + m88k-motorola-m88kbcs) + + The 19.26 pretest was reported to run on SVR3. However, if you + use --with-x-toolkit on svr3, you will have problems compiling some + files because time.h and sys/time.h get included twice. + One fix is to edit those files to protect against multiple inclusion. + + As of version 19.13, Emacs was reported to run under SYSVr3 and SYSVr4. + +Dual running System V (m68k-dual-sysv) + + As of 17.46, this worked except for a few changes + needed in unexec.c. + +Dual running Uniplus (m68k-dual-uniplus) + + Worked, as of 17.51. + +Elxsi 6400 (elxsi-elxsi-sysv) + + Changes for 12.0 release are in 19.1. + Dumping should work now. + +Encore machine (ns16k-encore-bsd) + + This machine bizarrely uses 4.2BSD modified to use the COFF format + for object files. Works (as of 18.40). For the APC processor you + must enable two lines at the end of `src/s/umax.h', which are commented + out in the file as distributed. + + WARNING: If you compile Emacs with the "-O" compiler switch, you + must also use the "-q enter_exits" switch so that all functions have + stack frames. Otherwise routines that call `alloca' all lose. + + A kernel bug in some system versions causes input characters to be lost + occasionally. + +Fujitsu DS/90 (sparc-fujitsu-sysv4) + + Changes merged in 20.3. + +GEC 63 (local-gec63-usg5.2) + + Changes are partially merged in version 18, but certainly require + more work. Let us know if you get this working, and we'll give it a + real configuration name. + +Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3) + + 18.36 worked on versions 1.2 and 2.0 of the operating system. + + On UTX/32 2.0, use pn-gould-bsd4.3. + + On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that + compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g + flag to cc in the makefile. + + UTX/32 1.3 has a bug in the bcopy library routine. Fix it by + #undef BSTRING in `src/m/gould.h'. + + Version 19 incorporates support for releases 2.1 and later of UTX/32. + A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h. + +Gould NP1 (np1-gould-bsd) + + Version 19 supposedly works. + +Harris Night Hawk (m68k-harris-cxux or m88k-harris-cxux) + + This port was added in 19.23. The configuration actually tested was + a Night Hawk 4800 running CX/UX 7.0. + + If you have GCC ported and want to build with it, you probably need to + change things (like compiler switches) defined in the s/cxux.h file. + + If you have X11R6 installed in /usr/lib, configure will fail to find + it and may find X11R5 instead. To work around this problem, use + --x-libraries=/usr/lib when you run configure. + + With CX/UX 7.0 and later releases, you need to build after setting the + SDE_TARGET environment variable to COFF (a port using ELF and shared + libraries has not yet been done). + +Harris Power PC (powerpc-harris-powerunix) + + Patches have been merged in 19.31. + +Honeywell XPS100 (xps100-honeywell-sysv) + + Config file added in version 19. + +Hewlett-Packard 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux + or m68k-hp-netbsd) + + These machines are 68000-series CPUs running HP/UX + (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah. + The operating system suffix determines which system Emacs is built for. + + Series 200 HPUX runs Emacs only if it has the "HP/UX upgrade". + + Version 19 works under BSD. The 19.26 pretest was reported + to work on HPUX 9. 19.31 works on HPUX 10.01, but there are + some problems on 10.10 which have not been resolved. Emacs 19.34 + works on HPUX 10.20 provided you compile with GCC; with the HP C + compiler, subprocess commands do not work. + + On HPUX 9, Emacs sometimes crashes with SIGBUS or SIGSEGV after you + delete a frame. We think this is due to a bug in the X libraries + provided by HP. With the alternative X libraries in + /usr/contrib/mitX11R5/lib, the problem does not happen. + + If you are running HP/UX release 8.0 or later, you need the optional + "C/ANSI C" software in order to build Emacs (older releases of HP/UX + do not require any special software). If the file "/etc/filesets/C" + exists on your machine, you have this software, otherwise you do not. + + Note that HP has used two incompatible assembler syntaxes, + and has recently changed the format of C function frames. + `src/crt0.c' and `src/alloca.s' have been conditionalised for the new + assembler and new function-entry sequence. You may need to define + OLD_HP_ASSEMBLER if you are using an older hpux version. If you + have an official (bought from HP) series 300 machine you have + the new assembler. Kernels that are 5.+ or later have new + assembler. A Series 200 that has been upgraded to a 68010 + processor and a 5.+ kernel has the new compiler. + + Define C_SWITCH_MACHINE to be +X to make a version of Emacs that + runs on both 68010 and 68020 based HP/UX's. + + Define HPUX_68010 if you are using the new assembler, for + a system that has a 68010 without a 68881. This is to say, + a s200 (upgraded) or s310. + + Define the symbol HPUX_NET if you have the optional network features + that include the `netunam' system call. This is referred to as + Network Services (NS/9000) in HP literature. + +HP 9000 series 500: not supported. + + The series 500 has a seriously incompatible memory architecture + which relocates data in memory during execution of a program, + and support for it would be difficult to implement. + +HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux + or ...hpux9shr, or ...-nextstep) + + Use hppa1.1 for the 700 series and hppa1.0 for the 800 + series machines. (Emacs may not actually care which one you use.) + + Support for NextSTEP was added in 19.31. + + Emacs 20 may work on HPUX 10. You need patch PHSS_6202 to install + the Xaw and Xmu libraries. On HPUX 10.20 you may need to compile with GCC; + when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03, + the subprocess features failed to work. + + 19.26 is believed to work on HPUX 9 provided you compile with GCC. + As of version 19.16, Emacs was reported to build (using GCC) and run + on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01. + The HP compiler is known to fail on some versions if you use +O3, + but it may work with lower optimization levels. + + Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9. + You may need to create the X libraries libXaw.a and libXmu.a from + the MIT X distribute, and you may need to edit src/Makefile's + definition of LIBXT to look like this: + + LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext + + Some people report trouble using the GNU memory allocator under + HP/UX version 9. The problems often manifest as lots of ^@'s in the + buffer. + + We are told that these problems go away if you obtain the latest + patches for the HP/UX C compiler. James J Dempsey + says that this set of versions works for him: + /bin/cc: + HP92453-01 A.09.28 HP C Compiler + /lib/ccom: + HP92453-01 A.09.28 HP C Compiler + HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93 + Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93 + + For 700 series machines, the HP-UX patch needed is known as + PHSS_2653. (Perhaps for 800 series machines as well; we don't + know.) If you are on the Internet, you should be able to obtain + this patch by using telnet to access the machine + support.mayfield.hp.com and logging in as "hpslreg" and following + the instructions there. Or you may be able to use this + web site: + + HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html + HP Support Line: http://support.mayfield.hp.com + + Please do not ask FSF for further support on this. If you have any + trouble obtaining the patch, contact HP Software Support. + + If your buffer fills up with nulls (^@) at some point, it could well + be that problem. That problem does not happen when people use GCC + to compile Emacs. On the other hand, the HP compiler version 9.34 + was reported to work for the 19.26 pretest. 9.65 was also reported to work. + + If you turn on the DSUSP character (delayed suspend), + Emacs 19.26 does not know how to turn it off on HPUX. + You need to turn it off manually. + + If you are running HP/UX release 8.0 or later, you need the optional + "C/ANSI C" software in order to build Emacs (older releases of HP/UX + do not require any special software). If the file "/etc/filesets/C" + exists on your machine, you have this software, otherwise you do not. + +High Level Hardware Orion (orion-highlevel-bsd) + + This is the original microprogrammed hardware. + Machine description file ought to work. + +High Level Hardware Orion 1/05 (clipper-highlevel-bsd) + + Changes merged in 18.52. This is the one with the Clipper cpu. + Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'. + + C compiler has a bug; it loops compiling eval.c. + Compile it by hand without optimization. + +HITACHI SR2001/SR2201 series (hppa1.1-hitachi-hiuxwe2) + + These machines are based on PA architecture running HI-UX/MPP + (based on OSF1. `MPP' stands for `Massively Parallel Processor'). + + Emacs 19.34 is believed to work; its pretest was tested + both on SR2001 (output of `uname -rv' is `00-01-BB 0') and + SR2201 (`02-00 0'). + + Emacs 20.7 was reported to build on a system whose `uname -rs' + output is `HI-UX/MPP 03-04'. + + The machine description file is `src/m/sr2k.h' is based on + `src/m/hp800.h'. The system description file is `src/s/hiuxwe2.h' + based on `src/s/osf1.h'. Note that this system doesn't use COFF. + +IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2) + + Changes merged in version 19. You may need to copy + /usr/lib/samples/hft/hftctl.c to the Emacs src directory. + + i386-ibm-aix1.1 may not work with certain new X window managers, and + may be suboptimal. + +IBM RS/6000 (rs6000-ibm-aix*) + + Emacs 19.26 is believed to work; its pretest was tested. + + Compiling with the system's `cc' and CFLAGS containing `-O5' might + fail because libXbsd isn't found. This is a compiler bug; + re-configure Emacs so that it isn't compiled with `-O5'. + + At last report, Emacs didn't run well on terminals. Informed + persons say that the tty VMIN and VTIME settings have been + corrupted; if you have a fix, please send it to us. + + Compiling with -O using the IBM compiler has been known + to make Emacs work incorrectly. It's reported that on + AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14, + cc -O fails for some files. You need to install any + PTF containing APAR #IX42810 to bring the compiler to + the 1.03.00.14 level to allow optimized compiles. + + There are reports that IBM compiler versions earlier than 1.03.00.02 + fail even without -O. However, another report said that compiler + version 1.02.01.00 did work, on AIX 3.2.4, with Emacs 19.31. + + As of 19.11, if you strip the Emacs executable, it ceases to work. + + If you are using AIX 3.2.3, you may get a core dump when loading + ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP + as -ltermcap -lcurses. Please tell us if this fails to work. + + If anyone can fix the above problems, or confirm that they don't happen + with certain versions of various programs, we would appreciate it. + +IBM RT/PC (romp-ibm-bsd or romp-ibm-aix) + + Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX. + 19.22 is reported to work under bsd.

The Cut, Paste and Copy items + in the menu bar Edit menu work with the clipboard. + + It's important to include the SunOS version number in the + configuration name. For example, for SunOS release 4.0 on a Sun 3, + use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use + `sparc-sun-sunos4.1'. For SunOS release 4.1.3 on a Sparc, use + `sparc-sun-sunos4.1.3'. Note that shared libraries are now + used by default on SunOS 4.1. + + A user reported irreproducible segmentation faults when using 19.29 + on Solaris 2.3 and 2.4 after compiling it with the Sun compiler. + The problem went away when GCC 2.7.0 was used instead. We do not know + whether anything in Emacs is partly to blame for this. + + X11R6 is set up to make shared libraries only, on Sunos 4. + Therefore, in order to link Emacs, you need to create static X libraries. + To do this, rebuild X11 after setting + #define ForceNormalLib YES + #define SeparateSharedCompile YES + in site.def (after #ifdef AfterVendorCF). + + Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations, + and `i386' for Sun Roadrunners. i386 calls for Sunos4.0. + + If you compile with Sun's ANSI compiler acc, you need additional options + when linking temacs, such as + /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1 + (those should be added just before the libraries) and you need to + add -lansi just before -lc. The precise file names depend on the + compiler version, so we cannot easily arrange to supply them. + + On SunOS 4.1.1, do not use /usr/5bin/cc. You can use gcc or/usr/bin/cc. + Make sure the environment variable LD_LIBRARY_PATH is not defined. + + Some people report crashes on SunOS 4.1.3 if SYSTEM_MALLOC is defined. + Others have reported that Emacs works if SYSTEM_MALLOC is defined, and not + if it is undefined. So far we do not know why results vary in this way. + The sources are set up so that SYSTEM_MALLOC is defined; if that crashes, + or if you want the benefit of the relocating memory allocator, you can + try enabling the #undef SYSTEM_MALLOC in src/s/sunos4-1-3.h. + + On Solaris 2, you need to install patch 100947-02 to fix a system bug. + Presumably this patch comes from Sun. You must alter the definition of + LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib. + You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH. + + On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is + reported to hang sometimes if it exits while it has one or more + subprocesses (e.g. the `wakeup' subprocess used by `display-time'). + Emacs and its subprocesses become zombies, and in their zombie state + slow down their host and disable rlogin and telnet. This is most + likely due to a bug in Solaris 2.2's multiprocessor support, + rather than an Emacs bug. + + On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make + sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before + /usr/ucb. (Most free software packages have the same requirement on + Solaris.) + + If you have trouble using open-network-stream, get the distribution + of `bind' (the BSD name-server), build libresolv.a, and link Emacs + with -lresolv, by copying the #definition of LIBS_SYSTEM in + src/s/sunos4-1.h to src/config.h. This problem is due to obsolete + software in the nonshared standard library. + + If you want to use SunWindows, define HAVE_SUN_WINDOWS + in config.h to enable a special interface called `emacstool'. + The definition must *precede* the #include "machine.h". + System version 3.2 is required for this facility to work. + + We recommend that you instead use the X window system, which + has technical advantages, is an industry standard, and is also + free software. The FSF does not support the SunWindows code; + we installed it only on the understanding we would not let it + divert our efforts from what we think is important. + + If you are compiling for X windows, and the X window library was + compiled to use the 68881, then you must edit config.h according + the comments at the end of `src/m/sun3.h'. + + Note that Emacs on a Sun is not really as big as it looks. + As dumped, it includes around 200k of zeros between the + original text section and the original data section + (now remapped as part of the text).

It may need more change to be correct. + + Use s/usg5-4.h for Esix System V 4.0.[34] systems if you also have + XFree86. If you insist on using the Esix X Window libraries, good + luck. s/esix5r4.h provides a starting point, but doesn't seem to + work consistently. The basic problems involve the need to load + -lX11 *last* in the link command, and even then some things break. + You get best results by installing XFree86 and forgetting about the + Esix stuff unless you want to run IXI xdt3, which really only needs + the Esix X11 shared libraries. + + To compile with XFree86, make sure that your LD_LIBRARY_PATH + contains /usr/X386/lib. Be careful if you also have the Esix X + Window libraries that /usr/X386/lib appears *first* in the + LD_LIBRARY_PATH. Then define C_SWITCH_X_SYSTEM -I/usr/X386/include. + +Linux (actually GNU/Linux) + + Most of the complete systems which use the Linux kernel are close + enough to the GNU system to be considered variant GNU systems. We + call them "Linux-based GNU systems," or GNU/Linux for short. + + It is not coincidence that many of the other components used with + Linux--including GNU Emacs--were developed specifically for the GNU + project. The GNU project was launched in 1984 to develop a free + complete Unix-like operating system. To reach this goal, we had to + develop whatever system components were not available as freely + redistributable software from some other source. + + The GNU project wants users of GNU/Linux systems to be aware of how + these systems relate to the GNU project, because that will help + spread the GNU idea that software should be free--and thus encourage + people to write more free software. See the file LINUX-GNU in this + directory for more explanation. + +Microport + + See under "Intel 386". + +MSDOS + + For installation on MSDOS, see the file INSTALL (search for `MSDOG', + near the end of the file). See the "MS-DOS" chapter of the manual + for information about using Emacs on MSDOS. + +SCO Unix + If you have TCP but not X, you need to edit src/s/sco4.h + to define HAVE_SOCKETS. + + If you are using MMDF instead of sendmail, you need to remove + /usr/lib/sendmail or modify lisp/paths.el before compiling. + lisp/paths.el (which is loaded during the build) will attempt to use + sendmail if it exists. + + If you are using SMAIL, you need to define the macro + SMAIL in config.h. + +System V rel 0 (usg5.0) + + Works, on Vaxes and 3bxxx's. + There are some problems in 18.37 due to shortnames/cccp problems: + use the emacs 17 cpp if you have it. + +System V rel 2 (usg5.2) + + Works on various machines. + On some (maybe all) machines the library -lPW exists and contains + a version of `alloca'. On these machines, to use it, put + #define HAVE_ALLOCA + #define LIB_STANDARD -lPW -lc + in the `src/m/MACHINENAME.h' file for the machine. + + If you find that the character Meta-DEL makes Emacs crash, + find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT] + and make it store 7 there. I have as yet no evidence of whether + this problem, known in HP/UX, exists in other system V versions. + +System V rel 2.2 (usg5.2.2) + + In 5.2.2 AT&T undid, incompatibly, their previous incompatible + change to the way the nlist library is called. A different s- file + is used to enable the other interface. + + They call themselves the right choice--can't they choose? + + Emacs version 18 unexec is currently not working properly + on 5.2.2. Nobody knows why yet. A workaround is to define + NO_REMAP. It is not yet known whether this applies to all + machines running 5.2.2. + +System V rel 3 (usg5.3) + + Some versions of this system support ptys and BSD-style sockets. + On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h. + + If you want to link Emacs with shared libraries, define + USG_SHARED_LIBRARIES. + + You may have to add ANSI idempotence #-lines to your sys/types.h + file to get Emacs to compile correctly. This may be necessary on + other pre-ANSI systems as well. + + On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support + cannot be made to work. Whether or not the GNU relocating malloc is + used, the symptom is that the first call Emacs makes to sbrk(0) returns + (char *)-1. Sorry, you're stuck with character-only mode. Try + installing Xfree86 to fix this. + +System V rel 4.0.3 and 4.0.4 (usg5.4) + + Supported, including shared libraries for ELF, but ptys do not work + because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have + fixed this). This failure is probably due to a misunderstanding of + the consequences of the POSIX spec: many system designers mistakenly + think that POSIX requires this feature to fail. This is untrue; + ptys are an extension, and POSIX says that extensions *when used* + may change the action of standard facilities in any fashion. + + If you get compilation errors about wrong number of + arguments to getpgrp, define GETPGRP_NO_ARG. + + The standard C preprocessor may generate xmakefile incorrectly. However, + /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp + seems to work OK under Dell 2.2. + + Some versions 3 and earlier of V.4, on the Intel 386 and 860, had + problems in the X11 libraries. These prevent Emacs from working + with X. You can use Emacs with X provided your copy of X is based + on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3). + Unfortunately, the only way you can tell whether your X11 library is + new enough is to try compiling Emacs to use X. If emacs runs, your + X11 library is new enough. + + In this context, GSV4 and GSV4i are alternate names for X11R4. + OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or + may not work, depending on who made the Unix system. If the library + libXol is part of the X distribution, then you have X11R3 and Emacs + won't work with X. + + Most versions of V.4 support sockets. If `/usr/lib/libsocket.so' + exists, your system supports them. If yours does not, you must add + #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h. + (Any system that supports Internet should implement sockets.) + +Ultrix (bsd4.3) + + Recent versions of Ultrix appear to support the features of Berkeley 4.3. + Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out. + + Ultrix 3.0 has incompatibilities in its X library if you have the + Ultrix version of X (UWS version 2.0). To solve them, you need to + prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says: + + I added the following lines to config.h after the X defines: + + #if defined(ultrix) && defined(X11) + #define OBJECTS_SYSTEM calloc.o + #endif + + Then I ran the following: + + ar x /usr/lib/libc.a calloc.o + + The problem is said to be gone in UWS version 2.1. + +Uniplus 5.2 (unipl5.2) + + Works, on Dual machines at least. + +VMS (vmsM.N) + + Richard Levitte distributes a set of patches to + Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably + won't work very well, or even compile. Levitte is working on a + port, so these problems should be fixed in the near future. + + Note that Emacs for VMS is usually distributed in a special VMS + distribution. See the file ../vms/VMSINSTALL for info on moving + Unix distributions to VMS, and other VMS-related topics. + +Windows NT/95/98/ME/2000 + + For installation on all versions of the MS-Windows platform, see the + file nt/INSTALL. + +Xenix (xenix) + + Should work in 18.50, but you will need to edit the files + `lib-src/Makefile' and `src/ymakefile' + (see the comments that mention "Xenix" for what to change.) + Compiling Emacs with -O is said not to work. + + If you want Emacs to work with Smail (installed as /usr/bin/smail) + then add the line #define SMAIL to config.h. + + The file etc/XENIX suggests some useful things to do to Xenix + to make the Emacs meta key work. + +Local variables: +mode: indented-text +fill-prefix: " " +End:
