Linux Tcl Kits which honor TMPDIR as opposed to hardwired /tmp/...
Robert Heller
http://www.equi4.com/pub/tk/downloads.html use /tmp/ as a *hardwired*
location for loading embedded shared libraries. Do there exist versions
that honor TMPDIR instead?

Not to my knowledge. We've worked around this problem (permissions
don't allow loading shared libraries from /tmp on some Linux systems) at
the application level, so that if the existing "load" of a shared
library from within the starkit fails, we catch that and manually copy
and load it from elsewhere.

I took a look at the kbskit source files (which I had handy), just to
see where /tmp was being used instead of TMPDIR.
Here are the only places I could find in the kbskit sources (and its
sources includes a few extensions that are addons...
tcl/compat/tmpnam.c - P_tmpdir uses hard coded /tmp
tcl/macosx/tclMacOSXNotify.c /tmp notifier log file
snack 2.2.10 wrap.tcl demo uses /tmp
img's libjpeg/jmemname.c uses /usr/tmp as temporary directory
img's libtiff's fax2ps tool uses /tmp for temporary fax file
iwidgets generic canvasprintbox writes a /tmp/xge file
sqlite 3.3.17 generic/tclsqlite3.c initializes a directory with the
/var/tmp, /usr/tmp, and /tmp dir names. However, it also makes
use of
TEMP/TMP/TMPDIR variables in a different place in the code.
tcllib's bench libbench.tcl uses $TEMP on windows and /tmp otherwise
for a temp file name.
tclx's edprocs.tcl uses /tmp for a temporary file
tkhtml 3.0's hv/tst_main.tcl uses /tmp for an image
xotcl 1.5.3's generic aol-xotcl.tcl uses /tmp for an working script
file
xotcl 1.5.3's library actiweb/WebDocument.xoltc uses /tmp for temp
files.
ditto library/comm/Httpd.xotcl uses /tmp/log for a log file
ditto library/comm/PCache.xotcl uses /tmp for cache

This is probably the one that is being used for copying shared libraries
to a place where the O/S can load them.

Wouldn't a platform-independent tmpdir/tmpfile function or an
extension to the 'file' command in the core or tcllib be a good idea?

Its already in tcllib: ::fileutil::tempdir and ::fileutil::tempfile
kind regards
