Possible problem with ctags

[Robert Mecklenburg]

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,

I can confirm this discovery. In fact, that is why I just started up
news, to report the problem. It is present with this version:

Exuberant Ctags 5.5, Copyright (C) 1996-2003 Darren Hiebert
Compiled: Apr 14 2003, 10:16:41
Addresses: <***@users.sourceforge.net>,
http://ctags.sourceforge.net
Optional compiled features: +wildcards, +regex, +internal-sort

(By the way, although this version announces itself as 5.5, it is really
5.5.3 according to /setup.exe.)

The full compiled-in directory it is trying to use, as found by both
FileMon and strings, is:

/mnt/c/DOCUME~1/liddins/LOCALS~1/Temp

The obvious workaround is "export TMPDIR=$TMP"

Shouldn't I just send email to straight to a cygwin developer or package maintainer?

Isn't personal email more efficient than using a mailing list? or
I don't want to bother the list with my problem. or
I'm not really sure if this is a real problem and want to find out before I bother the list.

According to setup.exe, it's 5.5-3. The -3 is the cygwin release number which
is not reflected in the version.

I will now put myself in the corner for one hour for failing to read the
directions. :) Sorry, won't happen again. At least it is also on the list.

Well that's a bit harsh for a first offense. I'd say 60 minutes would be
plenty.
