I have a fix for this problem. I got some pointers from people on
comp.text.tex, and poked around a bit. The problem is that getwd()
was hand rolled, since it is not universally available on all machines.
The function is located in common/extra.c .
If you machine has a getwd() function, then I would recommend using it,
otherwise you will need to hack the included function to work with the
AFS problems.
Compile the following and run it from various locations within AFS to see if
you have a builtin getwd() and to see if it will work in AFS.
#include <stdio.h>
char *getwd();
main() {
char buf[1024];
getwd(buf);
printf("cwd = %s\n", buf);
}
If this works, you're in fat city. Go to your TeX source directory
and edit common/extra.c
You will need to remove (or comment out) the getwd() function (lines: 503-566).
It starts out like this:
char *
getwd ()
{
struct stat root_stat, cwd_stat;
char *cwd_path = xmalloc (1);
*cwd_path = 0;
and ends up like this:
if (*cwd_path == 0)
cwd_path = "/";
else
/* Go back to where we were. */
checked_chdir (cwd_path);
return cwd_path;
}
then find where getwd is called (line: 607) -> cwd = getwd ();
and change this to read: cwd = getwd (xmalloc(1024));
Don't worry, xmalloc is defined in this file. That's all there is to
it, just recompile TeX now and your all set.
This has been tested on the following platforms:
IBM-RT and IBM-6152 running AOS4.3 (rt_aos4)
IBM RS/6000 running AIX3.1 (rs_aix31)
SUN4/110 and Sparc 1 running SunOS4.0.3 (sun4_40 & sun4c_40)
SUN3/60 and SUN3/280 running SunOS4.0.3 (sun3_40)
An additional advantage of this patch is that it is *MUCH* faster than
the method currently used.
Let me know if you want a diff of the above changes to patch your file.
Hope this helps.
