This file contains a collection of notes that various people have provided about porting Tcl to various machines and operating systems. I don't have personal access to any of these machines, so I make no guarantees that the notes are correct, complete, or up-to-date. In some cases, a person has volunteered to act as a contact point for questions about porting Tcl to a particular machine; in these cases the person's name and e-mail address are listed. --------------------------------------------- Cray machines running UNICOS: Contact: John Freeman (jlf@cray.com) --------------------------------------------- 1. The nm command on unicos doesn't have a -p option, so I removed it from the config script without apparent harm. diff -c -r1.1 config *** 1.1 1991/11/12 15:11:51 --- config 1991/11/12 15:14:18 *************** *** 57,63 **** echo " to set the libc variable." exit(1) endif ! nm -p $libc > tmp.libc if ( $status != 0 ) then echo "- ERROR\!\! Nm failed to extract names of system-supplied library" echo " procedures from $libc. You'll have to modify config by hand to" --- 57,63 ---- echo " to set the libc variable." exit(1) endif ! nm $libc > tmp.libc if ( $status != 0 ) then echo "- ERROR\!\! Nm failed to extract names of system-supplied library" echo " procedures from $libc. You'll have to modify config by hand to" 2. There is an error in the strstr function in UNICOS such that if the string to be searched is empty (""), the search will continue past the end of the string. Because of this, the history substitution loop will sometimes run past the end of its target string and trash malloc's free list, resulting in a core dump some time later. (As you can probably guess, this took a while to diagnose.) I've submitted a problem report to the C library maintainers, but in the meantime here is a workaround. ----------------------------------------------------------------- diff -c1 -r1.1 tclHistory.c *** 1.1 1991/11/12 16:01:58 --- tclHistory.c 1991/11/12 16:14:22 *************** *** 23,24 **** --- 23,29 ---- #include "tclInt.h" + + #ifdef _CRAY + /* There is a bug in strstr in UNICOS; this works around it. */ + #define strstr(s1,s2) ((s1)?(*(s1)?strstr((s1),(s2)):0):0) + #endif _CRAY --------------------------------------------- HP-UX systems: --------------------------------------------- 1. The #define for TCL_UNION_WAIT in tclUnix.h needs to be set to 0, not 1. I've tried a number of techniques to get the "config" script to figure this out and set it correctly, but so far I haven't been able to make it work for HP-UX systems. 2. It may also be useful to add the flag "-D_BSD" to CFLAGS in the Makefile, but I'm not sure this is necessary (and it may even be evil) if TCL_UNION_WAIT has been #define'd correctly. --------------------------------------------- MIPS systems runing EP/IX: --------------------------------------------- 1. Need to add a line "#include " in tclUnix.h. 2. Need to add "-lbsd" into the line that makes tclTest: ${CC} ${CFLAGS} tclTest.o libtcl.a -lbsd -o tclTest --------------------------------------------- IBM RS/6000 systems running AIX: --------------------------------------------- 1. The system version of strtoul is buggy, at least under some versions of AIX. If the expression tests fail, try forcing Tcl to use its own version of strtoul instead of the system version. To do this, first copy strtoul.c from the compat subdirectory up to the main Tcl directory. Then modify the Makefile so that the definition for COMPAT_OBJS includes "strtoul.o". Note: the "config" script should now detect the buggy strtoul and substitute Tcl's version automatically. 2. You may have to comment out the declaration of open in tclUnix.h. 3. The "nm -p ..." line in the file "config" has to be changed to "nm -en ..." if you use the version of nm that's in /bin. If you're set up to use the BSD version (in /usr/ucb) then this won't be a problem. --------------------------------------------- AT&T 4.03 OS: --------------------------------------------- Machine: i386/33Mhz i387 32k Cache 16MByte OS: AT&T SYSV Release 4 Version 3 X: X11R5 fixlevel 9 Xserver: X386 1.2 1. Change the Tk Makefile as follows: XLIB = -lX11 should be changed to: XLIB = -lX11 -lsocket -lnsl 2. Change the Tcl "config" script as follows: set libc="/lib/libc.a" should be changed to: set libc="/usr/ccs/lib/libc.a" ------------------------------------------------------- Motorola MPC's running UNIX System V/88 Release R32V2: ------------------------------------------------------- 1. Tcl should build without any modifications to sources, but csh isn't supplied with the operating system so you'll have to find and use the public-domain tcsh. ------------------------------------------------------- SGI machines running Irix release 4.0.1 or earlier: ------------------------------------------------------- 1. There's a bug in the optimizer; compile tclVar.c using -O0. 2. In tclUnix.h, add the following just before the declaration of environ: #ifdef __sgi #define environ _environ #endif --------------------------------------------- NeXT machines running NeXTStep 2.1: --------------------------------------------- 1. Change the "libc" definition in the config file to set libc="/lib/libsys_s.a" 2. Several of the "format" and "scan" tests will fail, but these are all minor nits stemming from imperfect POSIX compliance in the NeXT C library procedures. The errors are unlikely to affect any Tcl applications.
