Re: glibc cvs breaks JDK Mozilla plugin

[Jack Howarth <howarth at fuse dot net>]

Ulrich,
       I wouldn't be so quick to blame the mozilla script for being
buggy since this problem doesn't exist pre-10/21 in glibc cvs.
For comparision here is what the 10/20 glibc cvs snapshot does...

So it had no such problems finding libjvm.so. Also if you look back at my
previous message,
<http://sources.redhat.com/ml/libc-alpha/2000-10/msg00362.html>,
you will notice that the same paths are set successfully for libpthread.so.0.
It appears to me the problem is that the search path is being set twice for
libjvm.so
under the current glibc cvs...but not the pre-10/21 glibc cvs...

01714:   search cache=/etc/ld.so.cache

01714:    trying file=/usr/lib/libjvm.so

Hmmm....looking at this output from current glibc cvs what is the deal with the
system search path?
shouldn't it either appended to the previous search path or do two successive
searches in between
when the search path is reset to the system search path? I am suspecting it is
some internal
glibc bug causing the search path to get reset by accident to the system search
path.

ps I am attaching the mozilla and run-mozilla.sh scripts so you can see how they
handle
setting paths.
