Intel provides you:
-mkl_intel_lp64_dll.lib and mkl_intel_lp64.lib -mkl_intel_thread_dll.lib and mkl_intel_thread.lib (64 bit version) -mkl_core_dll.lib and mkl_core.lib (64 bit version) and they ask you to link against the _dll ones. I have not right here the exactly error, but it`s only an undefined reference to each lapack or blas call. I`m using gcc 4.5 (experimental) version ------------------------------------------------------------------------------ _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
