libmkl_scalapack_lp64.so: undefined reference to `MKL_SCALAPACK_INT'

emangus1 — Wed, 02 Sep 2009 13:25:39 GMT

Hello, I am evaluating the latest Intel Compiler suite. I am trying to link my program with latest MKL implmentation on a SGI workstation with xeon processor. I am having the following error:

/opt/intel/Compiler/11.1/046/mkl/lib/em64t/libmkl_scalapack_lp64.so: undefined reference to `MKL_SCALAPACK_INT'
/opt/intel/Compiler/11.1/046/mkl/lib/em64t/libmkl_scalapack_lp64.so: undefined reference to `Cdsendrecv'

I trace the problem back to the blacs implementation: I am using SGI's MPT library, so I uses libmkl_blacs_sgimpt_lp64.a library. For all blacs libraries, only the sgimpt version does not have MKL_SCALAPACK_INT defined. How do I get my program to link correctly?

Here are the library sequence I used to link with my program:

-lmkl_scalapack_lp64 -lmkl_blacs_sgimpt_lp64 -lmkl_lapack -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lmpi -ldl

Thanks

eleshia,
Probably linker adviser ( http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/)will helps you to select recommended linking line.

The problem has been reproduced. We'll provide a fix for this in a future update.

You could try this workaround: Compile a C source file with these two lines and link it in addition to MKL:

#include
int MKL_SCALAPACK_INT = (int) MPI_INT;

Hi Todd,

The C-file workaround you suggested takes care of only one of the two problems. While the message

libmkl_scalapack_lp64.so: undefined reference to `MKL_SCALAPACK_INT'

no longer appears, the other one, namely

libmkl_scalapack_lp64.so: undefined reference to `Cdsendrecv'

remains. Any further suggestions?

Thanks

Maurice

Maurice,

what mkl version you are using? We fixed this problem in 10.2 Update3.
