Lapack functions in MKL

Deleted_U_Intel — Mon, 19 Jan 2004 20:33:55 GMT

I'm using SGEQPF, SORMQR and SPOTRF functions from the Lapack library. I have downloaded and connected the trial version of the Intel MKL (I use mkl_s.lib mkl_lapack.lib mkl_ia32.lib). All BLAS functions (SAXPY, SDOT, etc.) are linked well, but I cannot link SGEQPF, SORMQR and SPOTRF.

Which library should I have for SGEQPF, SORMQR and SPOTRF?

Depending on the version of MKL you are using you should need to only link mkl_s.lib provided the library directory is on your path, even if set by the linker. I just tried this with the Intel compiler (linking mkl_c.lib) and the program linked properly. In my case I copied exampleslapacksourcesormqrx.f to the lapack directory and executed this line with the associated output:

From a distance this is difficult to analyze. In this case I would suggest submitting the issue to http://premier.intel.com. You should provide enough code for us to replicate the problem, if possible. It is always possible that there is a problem with the library code and your example may expose that.
