Description Robin Green 2005-04-06 20:26:26 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050328 Firefox/1.0.2 Fedora/1.0.2-3

Description of problem:
In the script /usr/bin/firefox, there is still some old code which uses LD_ASSUME_KERNEL=2.2.5, to be compatible with old Java virtual machines. This breaks on the latest glibc:

+ export LD_ASSUME_KERNEL=2.2.5
+ LD_ASSUME_KERNEL=2.2.5
++ /usr/lib/jvm/java-1.5.0-sun-1.5.0.01/jre/plugin/i386/ns7/../../../bin//java -version
++ grep version
grep: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
++ cut -f 3 -d ' '
++ sed -e 's/\"//g'
cut: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
sed: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
+ JVM_VERSION=
+ unset LD_ASSUME_KERNEL

strace shows that glibc.so.6 is being found and opened, but not "understood". Maybe this is related to the LinuxThreads move?

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Run firefox

Alternatively, just run:
LD_ASSUME_KERNEL=2.2.5 sh

Actual Results:  See above

Expected Results:  No errors; or, alternatively, a more helpful error message, e.g. "LD_ASSUME_KERNEL=2.2.5 is no longer supported".

Comment 1 Robin Green 2005-04-06 20:28:35 UTC

Sorry, I meant libc.so.6, not glibc.so.6, obviously.

Comment 2 Jakub Jelinek 2005-04-06 20:53:37 UTC

What firefox does has been wrong before as well, especially on non-i?86 arches.

The only program that should run with LD_ASSUME_KERNEL=2.2.5 in the environment
is java, not grep, cut or sed.
In FC4t2 LD_LIBRARY_PATH=/lib/obsolete/linuxthreads must be added to the
environment of that program as well.

I'm seeing this too with a fully up2date rawhide system, very annoying. Please
change status to assigned and fix.
