libmkl_intel_lp64.so incompatible

zer0nes — Wed, 07 Jul 2010 00:28:14 GMT

When I compile using:

mpiCC -o test test.o -L/opt/intel/mkl/lib/64 -lmkl -lvml -lm -lmpi

I got the following error:

/usr/bin/ld: skipping incompatible /opt/intel/mkl/lib/64/libmkl_intel_lp64.so when searching for libmkl_intel_lp64.so

What does it mean that the library is not compatible? It must have something to do with the x64 architecture but I can't be sure how to hack.

If you know how to fix this situation, I'd appreciate it.

Please check first architecture type on which you are working on. It may the on of the reason similar errors.You are linking with IA64 libraires( aka Itanium) but may be you need select em64t binaries.

The library was installed by the department system folks. With such information, can you tell how I should fix it? If you need more information for better help, let me know.

Thanks.

1) please change-L/opt/intel/mkl/lib/em64t instead of-L/opt/intel/mkl/lib/64

2)The link advisor at the top of the forum will give a suggestion appropriate to the platform combination

Problem solved. Thank you.

Ah, not quite solved. In the makefile, there's also -lvml. I found vml lib files in the em64t directory but the compiler keeps complaining

cannot find -lvml

Am I missing something?

Thanks for your help.

I have no idea. Just try to remove it. if you need VML functionality then all references will be resolved throughlibmkl_core lib.

btw, what version of MKL are you going to use?

I removed it and it works. Thanks.
