Linux64 : libippcore.so dynamic linking error related to libiomp5.so

Hello,

I hope someone can help, thanks in advance.

I am building a dynamic library that uses IPP.

The OS is Linux, 64 bit.

The point is, I am pointing to IPP libraries as part of the INTEL_COMPOSER_XE,

but instead of using Intel compiler, I have to use gcc.

I manage to correctly build the library, but at run time, I get the following error :

..../INTEL_COMPOSER_XE-2011.1.107/Linux64/composerxe-2011.1.107/ipp/lib/intel64/libippcore.so.7.0: symbol kmpc_set_affinity_mask_proc, version VERSION
not defined in file libiomp5.so with link time reference.

When I perform the associated ldd, I get (removing part of the path)

libiomp5.so => .../INTEL_COMPOSER_XE-2011.1.107/Linux64/composerxe-2011.1.107/compiler/lib/intel64/libiomp5.so (0x00002b78dd11f000)

Solved,

I had a problem with LD_LIBRARY_PATH that was not accounted for, and a different version of libomp5.so was used.

Hi Mathias,

Nice to know that issue has been resolved, you have to set LD_LIBRARY_PATH as mentioned din the user guide.
