Possible problem with ctags

Mon May 19 09:11:00 GMT 2003

I'm getting a strange error when I run ctags:
 5 osaka:cimsoft$ /bin/ctags -e --recurse
 ctags: cannot open temporary file : No such file or directory
 [Exit 1]
If I run this under strace I get:

I have no idea where the \mnt\c\DOCUME~1\liddins\LOCALS~1\Temp came
from. "liddins" is not a name which occurs anywhere on my machine,
our local subnet or the ctags source. In fact, a google on liddins
returns nothing (kind of cool, that).
After poking around some more I've found that setting the TMPDIR
environment variable to $TMP solves the problem. Scanning the source
I see that TMPDIR is used as a configuration option to specify a
default temporary directory. A strings on the ctags binary yeilds:
 12 osaka:cimsoft$ strings /bin/ctags.exe | grep liddins
 /mnt/c/DOCUME~1/liddins/LOCALS~1/Temp
My conclusion: Maybe the most recent release of ctags has a
compiled-in default directory of .../liddins/... and that this
directory is used if the TMPDIR environment variable is otherwise
undefined.
Comments?
Thanks,
