matmul_mkl

I receive this error during the build of openmpi-1.4.3 [both with and without configs that employ mkl]:
libopen-rte.so: undefined reference to `matmul_mkl_'

Is matmul_mkl used internally in building the new version 12 [icc, icpc or ifort, for Linux] libs? (It is NOT called by the openmpi code.) If so, which intel lib should be included in the build?

thanks.

in 12.0, there is a new library "libmatmul.a". This symbol is from this lib.

Did you have this flag "-opt-matmul" inv the compile options? if not, add it.
or try to add the lib to the linker.
