Problem with CBLAS example building

johnski — Tue, 23 Sep 2008 08:48:33 GMT

I'm running openSuSE 10.2 with a Core2 Quad and downloaded MKL 10.0.4 and installed it. All went well. I went to the example directory /opt/intel/mkl/10.0.4.023/examples/cblas and tried:

make so64 compiler=gnu and make so64 compiler=gnu

In both cases I get (except for the 32/64 difference):

gcc -w -I../../include source/cblas_sasumx.c source/common_func.c -L/opt/intel/mkl/10.0.4.023/lib/64 /opt/intel/mkl/10.0.4.023/lib/64/libmkl_intel_lp64.so /opt/intel/mkl/10.0.4.023/lib/64/libmkl_intel_thread.so /opt/intel/mkl/10.0.4.023/lib/64/libmkl_core.so /opt/intel/mkl/10.0.4.023/lib/64/libguide.so -lpthread -lm -o _results/gnu_lp64_parallel_64_so/cblas_sasumx.out
/opt/intel/mkl/10.0.4.023/lib/64/libmkl_intel_lp64.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

What am I doing wrong? It should quite simple but ...?

You are attempting to link with the Itanium libraries. Those should not be installed on Core 2, if you followed normal installation procedure. For Core 2 x86-64 SuSE platform, you need the mkl libraries from /lib/em64t/.

I was aware of the IA64 vs x86-64 problem - BUT I ran the install script selecting pretty much the only options to select. There was no IA64 vs x86-64 question(s) during this procedure.

I ran find / -name "em64t" -type d and got:

/opt/intel/mkl/10.0.4.023/lib/em64t
/opt/intel/mkl/10.0.4.023/benchmarks/mp_linpack/lib_hybrid/em64t
/opt/intel/mkl/10.0.4.023/benchmarks/mp_linpack/bin_intel/em64t

Am I missing something?
