MKL 9.1 Linking a shared lib that uses mkl_solver.a on LINUX em64t

[AndrewC]

I think something slipped through the QA cracks.
I cannot link my shared library with the mkl solver lib on Linux em64t. This used to work fine under MKL 9.0.
libmkl_solver.a is a static library, but that should not prevent it being linked as part of a shared library. Looks like someone forgot to compile it fPIC.


ld: /opt/intel/mkl/9.1/lib/em64t/libmkl_solver.a(util.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/opt/intel/mkl/9.1/lib/em64t/libmkl_solver.a: could not read symbols: Bad value

This sounds like an error and should be submitted to your Premier account at http://premier.intel.com. If you do that this issue will get logged into the system, get thoroughly checked out, and tracked. I would appreciate your submitting this to start the evaluation and repair, if appropriate, process.

Thanks,

I have submitted a problem report

[Intel_C_Intel]

Thanks. I think is the best way for this issue.

We are also seeing a very similar problem on linux 64bit but we are using MKL 10.0.012 - which presumably means this bug has still not been fixed?

Thank you!

ld: ../lib/libguide.a(kmp_csupport.o): relocation R_X86_64_32 can not be used when making a shared object; recompile with -fPIC

../lib/libguide.a: could not read symbols: Bad value

make: *** [../bin/libCK.so] Error 1

[AndrewC]

The bug I saw was definitely fixed. You probably need to link to the shared library version of libguide.

Thank you for the quick reply. We want to use static libraries to avoid having to ship re-distributables. Is there a way around this that doesnt involve shared libraries please?

Thank you

Tony

The only work around I can think of if you absolutely do not want to ship libguide.so would be to ask Intel nicely to compile libguide.a with -fPIC. It does seem like an oversight on their part.

To address this bug the threading libraries were built with -fPIC in Update 3 which was made available in April.
