[Nix-dev] ldconfig problem with patchelf and 64-bit libs

Wed, 05 May 2010 14:18:59 -0700 

I'm using patchelf to add rpath to some libraries, both 32 and 64-bit.
They both seem to work with executables, but ldconfig complains about the 64-bit lib: 
   /sbin/ldconfig: file ./liblwes64.so is truncated
I've looked at the section offsets and sizes, etc, and I didn't yet find anything that 
points past the end-of-file. Also, readelf hasn't complained about anything.
I'm including the file listing and some readelf output.

Any idea what might be wrong?
Let me know if there's any other info I can provide...

Thanks!
