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.
|
|
If you see the word "I" in any explanations, it refers to the person
|
|
who contributed the information, not to me; this means that I
|
|
probably can't answer any questions about any of this stuff. 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. I'm
|
|
interested in getting new porting information to add to the file;
|
|
please mail updates to "john.ousterhout@eng.sun.com".
|
|
|
|
This file reflects information provided for Tcl 7.4 and later releases.
|
|
If there is no information for your configuration in this file, check
|
|
the file "porting.old" too; it contains information that was
|
|
submitted for Tcl 7.3 and earlier releases, and some of that information
|
|
may still be valid.
|
|
|
|
A new porting database has recently become available on the Web at
|
|
the following URL:
|
|
http://www.sunlabs.com/cgi-bin/tcl/info.4.0
|
|
This page provides information about the platforms on which Tcl 7.4
|
|
and Tk 4.0 have been compiled and what changes were needed to get Tcl
|
|
and Tk to compile. You can also add new entries to that database
|
|
when you install Tcl and Tk on a new platform. The Web database is
|
|
likely to be more up-to-date than this file.

|
|
Solaris, various versions
|
|
--------------------------------------------
|
|
|
|
1. If typing "make test" results in an error message saying that
|
|
there are no "*.test" files, or you get lots of globbing errors,
|
|
it's probably because your system doesn't have cc installed and
|
|
you used gcc. In order for this to work, you have to set your
|
|
CC environment variable to gcc and your CPP environment variable
|
|
to "gcc -E" before running the configure script.
|
|
|
|
2. Make sure that /usr/ucb is not in your PATH or LD_LIBRARY_PATH
|
|
environment variables; this will cause confusion between the new
|
|
Solaris libraries and older UCB versions (Tcl will expect one version
|
|
and get another).
|
|
|
|
3. There have been several reports of problems with the "glob" command.
|
|
So far these reports have all been for older versions of Tcl, but
|
|
if you run into problems, edit the Makefile after "configure" is
|
|
run and add "-DNO_DIRENT_H=1" to the definitions of DEFS. Do this
|
|
before compiling.
|
|
|
|
--------------------------------------------
|
|
Pyramid DC/OSx SVr4, DC/OSx version 94c079
|
|
--------------------------------------------
|
|
|
|
Tcl seems to dump core in cmdinfo.test when compiled with the
|
|
optimiser turned on in TclEval which calls 'free'. To get around
|
|
this, turn the optimiser off.
|
|
|
|
--------------------------------------------
|
|
SGI machines, IRIX 5.2, 5.3, IRIX64 6.0.1
|
|
--------------------------------------------
|
|
|
|
1. If you compile with gcc-2.6.3 under some versions of IRIX (e.g.
|
|
4.0.5), DBL_MAX is defined too large for gcc and Tcl complains
|
|
about all floating-point values being too large to represent.
|
|
If this happens, redefining DBL_MAX to 9.99e299.
|
|
|
|
2. Add "-D_BSD_TIME" to CFLAGS in Makefile. This avoids type conflicts
|
|
in the prototype for the gettimeofday procedure.
|
|
|
|
2. If you're running under Irix 6.x and tclsh dumps core, try
|
|
removing -O from the CFLAGS in Makefile and recompiling; compiler
|
|
optimizations seem to cause problems on some machines.
|
|
|
|
--------------------------------------------
|
|
IBM RTs, AOS
|
|
--------------------------------------------
|
|
|
|
1. Steal fmod from 4.4BSD
|
|
2. Add a #define to tclExpr such that:
|
|
extern double fmod();
|
|
is defined conditionally on ibm032
|
|
|
|
--------------------------------------------
|
|
QNX 4.22
|
|
--------------------------------------------
|
|
|
|
tclPort.h
|
|
- commented out 2 lines containing #include <sys/param.h>
|
|
|
|
tcl.h
|
|
- changed #define VARARGS ()
|
|
- to #ifndef __QNX__
|
|
#define VARARGS ()
|
|
#else
|
|
#define VARARGS (void *, ...)
|
|
#endif
|
|
|
|
--------------------------------------------
|
|
Interactive UNIX
|
|
--------------------------------------------
|
|
|
|
Add the switch -Xp to LIBS in Makefile; otherwise strftime will not
|
|
be found when linking.
|
|
|
|
--------------------------------------------
|
|
Motorola SVR4 V4.2 (m88k)
|
|
--------------------------------------------
|
|
|
|
For Motorola Unix R40V4.2 (m88k architechure), use /usr/ucb/cc instead of
|
|
/usr/bin/cc. Otherwise, the compile will fail because of conflicts over
|
|
the gettimeofday() call.
|
|
|
|
Also, -DNO_DIRENT_H=1 is required for the "glob" command to work.
|
|
|
|
--------------------------------------------
|
|
NeXTSTEP 3.x
|
|
--------------------------------------------
|
|
|
|
Here's the set of changes I made to make 7.5b3 compile cleanly on
|
|
NeXTSTEP3.x.
|
|
|
|
Here are a couple lines from unix/Makefile:
|
|
|
|
# Added utsname.o, which implements a uname() emulation for NeXTSTEP.
|
|
COMPAT_OBJS = getcwd.o strtod.o tmpnam.o utsname.o
|
|
|
|
TCL_NAMES=\
|
|
-Dstrtod=tcl_strtod -Dtmpnam=tcl_tmpnam -Dgetcwd=tcl_getcwd \
|
|
-Dpanic=tcl_panic -Dmatherr=tcl_matherr \
|
|
-Duname=tcl_uname -Dutsname=tcl_utsname
|
|
|
|
# Added mode_t, pid_t, and O_NONBLOCK definitions.
|
|
AC_FLAGS = -DNO_DIRENT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_SYS_TIME_H=1
|
|
-DTIME_WITH_SYS_TIME=1 -DHAVE_TM_ZONE=1 -DHAVE_TM_GMTOFF=1 -DHAVE_TIMEZONE_VAR=1
|
|
-DSTDC_HEADERS=1 -Dmode_t=int -Dpid_t=int -DO_NONBLOCK=O_NDELAY ${TCL_NAMES}
|
|
|
|
|
|
Here are diffs for other files. utsname.[hc] are a couple files I added
|
|
to compat/ I'm not clear whether that's where they legitimately belong
|
|
- I considered stashing them in tclLoadNext.c instead. The tclIO.c
|
|
change was a bug, I believe, which I reported on comp.lang.tcl and
|
|
has apparently been noted and fixed. The objc_loadModules() change
|
|
allows "load" to load object code containing Objective-C code in
|
|
addition to plain C code.

SCO Unix 3.2.4 (ODT 3.0)
|
|
--------------------------------------------
|
|
|
|
The macro va_start in /usr/include/stdarg.h is incorrectly terminated by
|
|
a semi-colon. This causes compile of generic/tclBasic.c to fail. The
|
|
best solution is to edit the definition of va_start to remove the `;'.
|
|
This will fix this file for anything you want to compile. If you don't have
|
|
permission to edit /usr/include/stdarg.h in place, copy it to the tcl unix
|
|
directory and change it there.
|
|
|
|
Contact me directly if you have problems on SCO systems.

Linux 1.2.13 (gcc 2.7.0, libc.so.5.0.9)
|
|
--------------------------------------------
|
|
|
|
Symptoms:
|
|
|
|
* Some extensions could not be loaded dynamically, most
|
|
prominently Blt 2.0
|
|
|
|
The given error message essentially said:
|
|
Could not resolve symbol '__eprintf'.
|
|
|
|
(This procedure is used by the macro 'assert')
|
|
|
|
Cause
|
|
|
|
* '__eprintf' is defined in 'libgcc.a', not 'libc.so.x.y'.
|
|
It is therefore impossible to load it dynamically.
|
|
|
|
* Neither tcl nor tk make use of 'assert', thereby
|
|
preventing a static linkage.
|
|
|
|
Workaround
|
|
|
|
* I included <assert.h> in 'tclAppInit.c' / 'tkAppInit.c'
|
|
and then executed 'assert (argc)' just before the call
|
|
to Tcl_Main / Tk_Main.
|
|
|
|
This forced the static linkage of '__eprintf' and
|
|
everything went fine from then on.
|
|
|
|
(Something like 'assert (1)', 'assert (a==a)' is not
|
|
sufficient, it will be optimized away).
|
|
|
