Hi,

I am sharing this as somebody else can bump into the same problem.

I tried to use darshan shared library. After exporting LD_PRELOAD for /homes/fisaila/software/darshan/lib/libdarshan.so I had the following error in the shell:

make: symbol lookup error: /homes/fisaila/software/darshan/lib/libdarshan.so: undefined symbol: dlsym

The problem turned to be the default behavior of ld. In the darshan-runtime/Makefile I added -Wl,--no-as-needed to CFLAGS_SHARED (after -shared), recompiled and reinstalled the library and everything worked fine.

I am on Ubuntu 12.04 with gcc version 4.6.3.
