This is an old version of the file "porting.notes". It contains
|
|
porting information that people submitted for Tcl releases numbered
|
|
7.3 and earlier. You may find information in this file useful if
|
|
there is no information available for your machine in the current
|
|
version of "porting.notes".
|
|
|
|
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.

Cray machines running UNICOS:
|
|
Contact: John Freeman (jlf@cray.com)
|
|
---------------------------------------------
|
|
|
|
1. 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.

MIPS systems runing EP/IX:
|
|
---------------------------------------------
|
|
|
|
1. Need to add a line "#include <bsd/sys/time.h>" 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. You may need to add "-D_BSD -lbsd" to the CFLAGS definition. This
|
|
causes the system include files to look like BSD include files and
|
|
causes C library routines to act like bsd library routines. Without
|
|
this, the system may choke on "struct wait".

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
|
|
|
|
-------------------------------------------------------
|
|
Silicon Graphics systems:
|
|
-------------------------------------------------------
|
|
|
|
1. Change the CC variable in the Makefile to:
|
|
|
|
CC = cc -xansi -D__STDC__ -signed
|
|
|
|
2. In Irix releases 4.0.1 or earlier the C compiler has a buggy optimizer.
|
|
If Tcl fails its test suite or generates inexplicable errors,
|
|
compile tclVar.c with -O0 instead of -O.
|
|
|
|
3. For IRIX 5.1 or later, comments 1 and 2 are no longer relevant,
|
|
but you must add -D_BSD_SIGNALS to CFLAGS to get the proper signal
|
|
routines.
|
|
|
|
4. Add a "-lsun" switch in the targets for tclsh and tcltest,
|
|
just before ${MATH_LIBS}.
|
|
|
|
5. Rumor has it that you also need to add the "-lmalloc" library switch
|
|
in the targets for tclsh and tcltest.
|
|
|
|
6. In IRIX 5.2 you'll have to modify Makefile to fix the following problems:
|
|
- The "-c" option is illegal with this version of install, but
|
|
the "-F" switch is needed instead. Change this in the "INSTALL ="
|
|
definition line.
|
|
- The order of file and directory have to be changed in all the
|
|
invocations of INSTALL_DATA or INSTALL_PROGRAM.

NeXT machines running NeXTStep 3.1:
|
|
---------------------------------------------
|
|
|
|
1. Run configure with predefined CPP:
|
|
CPP='cc -E' ./configure
|
|
(If your shell is [t]csh, do a "setenv CPP 'cc -E' ")
|
|
|
|
2. Edit Makefile:
|
|
-add tmpnam.o to COMPAT_OBJS:
|
|
COMPAT_OBJS = getcwd.o waitpid.o strtod.o tmpnam.o
|
|
-add the following to AC_FLAGS:
|
|
-Dstrtod=tcl_strtod
|
|
|
|
3. Edit compat/tmpnam.c and replace "/usr/tmp" with "/tmp"
|
|
|
|
After this, tcl7.0 will be build fine on NeXT (ignore linker warning)
|
|
and run all the tests. There are some formatting problems in printf() or
|
|
scanf() which come from NeXT's lacking POSIX conformance. Ignore those
|
|
errors, they don't matter much.
|
|
|
|
4. Additional information that may apply to NeXTStep 3.2 only:
|
|
|
|
The problem on NEXTSTEP 3.2 is that the configure script makes some
|
|
bad assumptions about the uid_t and gid_t types. Actually, the may
|
|
have been valid for NEXTSTEP 3.0, or it may be NEXTSTEP's rudimentary
|
|
attempt at POSIX support under 3.2, but no matter what the reason, the
|
|
configure script sets up the Makefile with CFLAGS '-Duid_t=int' and
|
|
'-Dgid_t=int', which are, unfortunately, incorrect, since they shoudl
|
|
actually be (I think) unsigned shorts. This causes problems when the
|
|
'stat' structure is included, since it throws off the field offsets
|
|
from what the 'fstat' function thinks they should be.
|
|
|
|
Anyway, the quick fix is to run configure and then edit the Makefile
|
|
to remove the uid_t and gid_t defines. This will allow tcl and Tk to
|
|
compile and run. There are some other problems on NEXTSTEP,
|
|
specifically with %g in the printf family of functions, but making the
|
|
uid_t and gid_t change will get it up and running.
|
|

|
NeXT machines running NeXTStep 3.2:
|
|
---------------------------------------------
|
|
|
|
1. Run configure with predefined CPP:
|
|
CPP='cc -E' ./configure
|
|
(If your shell is [t]csh, do a "setenv CPP 'cc -E' ")
|
|
|
|
2. Edit Makefile:
|
|
-add tmpnam.o to COMPAT_OBJS:
|
|
COMPAT_OBJS = getcwd.o waitpid.o strtod.o tmpnam.o
|
|
-add the following to AC_FLAGS:
|
|
-Dstrtod=tcl_strtod
|
|
-add '-m' to MATH_LIBS:
|
|
MATH_LIBS = -m -lm
|
|
-add '-O2 -arch m68k -arch i386' to CFLAGS:
|
|
CFLAGS = -O2 -arch m68k -arch i386
|
|
|
|
-------------------------------------------------
|
|
ISC 2.2 UNIX (using standard ATT SYSV compiler):
|
|
-------------------------------------------------
|
|
|
|
In Makefile, change
|
|
|
|
CFLAGS = -g -I. -DTCL_LIBRARY=\"${TCL_LIBRARY}\"
|
|
|
|
to
|
|
|
|
CFLAGS = -g -I. -DPOSIX_JC -DTCL_LIBRARY=\"${TCL_LIBRARY}\"
|
|
|
|
This brings in the typedef for pid_t, which is needed for
|
|
/usr/include/sys/wait.h in tclUnix.h.
|
|
|
|
---------------------------------------------
|
|
DEC Alphas:
|
|
---------------------------------------------
|
|
|
|
1. There appears to be a compiler/library bug that causes core-dumps
|
|
unless you compile tclVar.c without optimization (remove the -O compiler
|
|
switch). The problem appears to have been fixed in the 1.3-4 version
|
|
of the compiler.
|
|
|
|

|
|
CDC 4680MP, EP/IX 1.4.3:
|
|
---------------------------------------------
|
|
|
|
The installation was done in the System V environment (-systype sysv)
|
|
with the BSD extensions available (-I/usr/include/bsd and -lbsd). It was
|
|
built with the 2.20 level C compiler. The 2.11 level should not be used
|
|
because it has a problem with detecting NaN values in lines like:
|
|
if (x != x) ...
|
|
which appear in the TCL code.
|
|
|
|
To make the configure script find the BSD extensions, I set environment
|
|
variable DEFS to "-I/usr/include/bsd" and LIBS to "-lbsd" before
|
|
running it. I would have also set CC to "cc2.20", but that compiler
|
|
driver has a bug that loader errors (e.g. not finding a library routine,
|
|
which the script uses to tell what is available) do not cause an error
|
|
status to be returned to the shell (but see the comments about "-non_shared"
|
|
below in the 2.1.1 notes).
|
|
|
|
There is a bug in the <sys/wait.h> include file that mis-defines the
|
|
structure fields and causes WIFEXITED and WIFSIGNALED to return incorrect
|
|
values. My solution was to create a subdirectory "sys" of the main TCL
|
|
source directory and put a corrected wait.h in it. The "-I." already on
|
|
all the compile lines causes it to be used instead of the system version.
|
|
To fix this, compare the structure definition in /usr/include/bsd/sys/wait.h
|
|
with /bsd43/include/sys/wait.h (or mail to John Jackson, jrj@cc.purdue.edu,
|
|
and he'll send you a context diff).
|
|
|
|
After running configure, I made the following changes to Makefile:
|
|
|
|
1) In AC_FLAGS, change:
|
|
-DNO_WAIT3=1
|
|
to
|
|
-DNO_WAIT3=0 -Dwait3=wait2
|
|
EP/IX (in the System V environment) provides a wait2() system
|
|
call with what TCL needs (the WNOHANG flag). The extra parameter
|
|
TCL passes to what it thinks is wait3() (the resources used by
|
|
the child process) is always zero and will be safely ignored.
|
|
|
|
2) Change:
|
|
CC=cc
|
|
to
|
|
CC=cc2.20
|
|
because of the NaN problem mentioned earlier. Skip this if the
|
|
default compiler is already 2.20 (or later).
|
|
|
|
3) Add "-lbsd" to the commands that create tclsh and tcltest
|
|
(look for "-o").
|
|
|
|
---------------------------------------------
|
|
CDC 4680MP, EP/IX 2.1.1:
|
|
---------------------------------------------
|
|
|
|
The installation was done in the System V environment (-systype sysv)
|
|
with the BSD extensions available (-I/usr/include/bsd and -lbsd). It was
|
|
built with the 3.11 level C compiler. The 2.11 level should not be used
|
|
because it has a problem with detecting NaN values in lines like:
|
|
if (x != x) ...
|
|
which appear in the TCL code. The 2.20 compiler does not have this
|
|
problem.
|
|
|
|
To make the configure script find the BSD extensions, I set environment
|
|
variable DEFS to:
|
|
|
|
"-I/usr/include/bsd -D__STDC__=0 -non_shared"
|
|
|
|
and LIBS to:
|
|
|
|
"-lbsd"
|
|
|
|
before running it. The "-non_shared" is needed because with shared
|
|
libraries, the compiler (actually, the loader) does not report an
|
|
error for "missing" routines. The configuration script depends on this
|
|
error to know what routines are available. This is the real problem
|
|
I reported above for EP/IX 1.4.3 that I incorrectly attributed to a
|
|
compiler driver bug. I don't have 1.4.3 available any more, but it's
|
|
possible using "-non_shared" on it would have solved the problem.
|
|
|
|
The same <sys/wait.h> bug exists at 2.1.1 (yes, I have reported it to
|
|
CDC), and the same fix as described in the 1.4.3 porting notes works.
|
|
|
|
In addition to the three Makefile changes described in the 1.4.3 notes,
|
|
you can remove the "-non_shared" flag from AC_FLAGS. It is only needed
|
|
for the configuration step, not the build.
|
|
|
|
You will get duplicate definition compilation warnings of:
|
|
|
|
DBL_MIN
|
|
DBL_MAX
|
|
FLT_MIN
|
|
FLT_MAX
|
|
|
|
during tclExpr.c. These can be ignored.
|
|
|
|
During expr.test, you will get a failure for one of the "fmod" tests
|
|
unless you have CDC patch CC40038311 installed.

Convex systems, OS 10.1 and 10.2:
|
|
Contact: Lennart Sorth (ls@dmi.min.dk)
|
|
---------------------------------------------
|
|
|
|
1. tcl7.0b2 compiles on Convex systems (OS 10.1 and 10.2) by just running
|
|
configure, typing make, except tclUnixUtil.c needs to be compiled
|
|
with option "-pcc" (portable cc, =!ANSI) due to:
|
|
cc: Error on line 1111 of tclUnixUtil.c: 'waitpid' redeclared:
|
|
incompatible types.
|
|
|
|
-------------------------------------------------
|
|
Pyramid, OSx 5.1a (UCB universe, GCC installed):
|
|
-------------------------------------------------
|
|
|
|
1. The procedures memcpy, strchr, fmod, and strrchr are all missing,
|
|
so you'll need to provide substitutes for them. After you do that
|
|
everything should compile fine. There will be one error in a scan
|
|
test, but it's an obscure one because of a non-ANSI implementation
|
|
of sscanf on the machine; you can ignore it.
|
|
|
|
2. You may also have to add "tmpnam.o" to COMPAT_OBJS in Makefile:
|
|
the system version appears to be bad.
|
|
|
|
-------------------------------------------------
|
|
Encore 91, UMAX V 3.0.9.3:
|
|
-------------------------------------------------
|
|
|
|
1. Modify the CFLAGS assignment in file Makefile.in to include the
|
|
-DENCORE flag in Makefile:
|
|
|
|
CFLAGS = -O -DENCORE
|
|
|
|
2. "mkdir" does not by default create the parent directories. The mkdir
|
|
directives should be modified to "midir -p".
|
|
|

|
|
Sequent machines running Dynix:
|
|
Contact: Andrew Swan (aswan@soda.berkeley.edu)
|
|
-------------------------------------------------
|
|
|
|
1. Use gcc instead of the cc distributed by Sequent
|
|
|
|
2. The distributed math library does not include the fmod
|
|
function. Source for fmod can be retrieved from a BSD
|
|
source archive (such as ftp.uu.net) and included in the
|
|
compat directory. Add fmod.o to the COMPAT_OBJS variable
|
|
in the Makefile. You may need to comment out references
|
|
to 'isnan' and 'finite' in fmod.c
|
|
|
|
3. If the linker complains that there are two copies of the
|
|
'tanh' function, use the ar command to extract the objects
|
|
from the math library and build a new one without tanh.o
|
|
|
|
4. The *scanf functions in the Sequent libraries are apparently
|
|
broken, which will cause the scanning tests to fail. The
|
|
cases that fail are fairly obscure. Using GNU libc apparently
|
|
solves this problem.
|

Systems running FreeBSD 1.1.5.1:
|
|
-------------------------------------------------
|
|
|
|
The following changes comprise the entire porting effort of tcl7.3 to
|
|
FreeBSD (i.e. these were the changes to tclTest.c) and should probably
|
|
be made part of the tcl distribution. The changes only effect the way that
|
|
floating point exceptions are reported. I've choosen to move the changes
|
|
out of tclTest.c and into tclBasic.c.
|
|
|
|
in tclBasic.c at top-of-file:
|
|
|
|
#ifdef BSD_NET2
|
|
#include <floatingpoint.h>
|

#endif
|
