Example does not run

I am trying to run ScaLAPACK, through MKL. Since I have the student version, I had to install MPICH2, since what I want to do is to apply an inverse of a matrix, that can be done with Cholesky in a distributed environment.

I got this ex1.c from Intell 11. It compliles fine, but it fails to execute:

Moreover, the same happens with Ying's example from here, which terrifies me:

gsamaras@pythagoras:~/konstantis$ ../mpich-install/bin/mpic++ -o test n.cpp -I../intel/mkl/include  ../intel/mkl/lib/intel64/libmkl_scalapack_ilp64.a -Wl,--start-group ../intel/mkl/lib/intel64/libmkl_intel_ilp64.a ../intel/mkl/lib/intel64/libmkl_core.a ../intel/mkl/lib/intel64/libmkl_sequential.a -Wl,--end-group ../intel/mkl/lib/intel64/libmkl_blacs_intelmpi_ilp64.a -lpthread -lm -ldl

===================================================================================

and this happens at this line of the code:

printf("here\n");
    locR = numroc_(&matrix_size, &block, &myrow, &izero, &nprow);
printf("here1\n");

I wanted to execute these examples, so that I know that I am good to go for developing my code. Is there a problem with the examples (which I do not really need to run), or is there a problem with MKL's ScaLAPACK?
