error while loading shared libraries: libpthread.so.0: ?????

/usr/contrib/Cadence/tools/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

I've added /usr/lib to my LD_LIBRARY_PATH, but in viewing /usr/lib, there is no libpthread.so.0 only libpthread.so. I don't know if that matters or how these files work but just guessing at it.

Linux HOSTNAME 2.6.18-53.el5 #1 SMP Mon Nov 12 02:14:55 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

I'm running CentOS on a 64 bit machine.

Any ideas? Thanks.

Is it in /lib ?

Okay, so you were right it was in /lib/ but since I'm running on a 64 bit machine I added /lib64/ to my PATH and LD_LIBRARY_PATH. I then got the following error

wrong ELF class: ELFCLASS64

So I figured I guess I should use the 32 bit version and changed the env variables to have /lib/ instead of /lib64/.

But that brings me back to the original error

error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

What tells you ldd on this java binary? And do you have something that starts with libpthread in lib64.

What do you mean by "ldd on this java binary"?

Also, in /lib64/ I have the following files that match

[USERNAME@HOSTNAME /]$ ls /lib64/libpthread
libpthread-2.5.so libpthread.so.0

ldd /usr/contrib/..../java

That's a cool command. This is the ldd output

It would seem it's trying to depend on the 32 bit version when it should be trying for the 64bit version. Am I right?

linux-gate.so.1 => (0xffffe000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00d4c000)
libdl.so.2 => /lib/libdl.so.2 (0x00d65000)
libc.so.6 => /lib/libc.so.6 (0x00bde000)
/lib/ld-linux.so.2 (0x00bc0000)

Yes there is some kind of conflict. Not sure where.. Crapy software that installs its own java.. Maybe cadence only works with 32 bits? Reinstall java 32 in /usr/local and change jre home to point there? Call the support?

Sorry not idea right now..

I'll have to give those a try.

The funny thing about support with Cadence. They will not even talk to you if you're not using RHEL 4 or 5. Even though CentOS really is RH they don't believe you. I can't dump my install right now.

My company had cadence running in solaris i think. Looks like google gives a lot of results, probably a java forum would be the place to ask
