### Some problem when using Scalapack_installer

Posted:

**Fri Jan 21, 2011 12:28 pm**Dear lapack/scalapack user,

I have met some problem when compiling Scalapack with Scalapack_installer_0.96 on Ubuntu 10.04. I wonder if anyone could help me about it.

I have compiled Blas(with gfortran), Lapack(with gfortran), and Blacs(with mpif77, mpicc) respectively. I used the software MPICH2 for MPI library.

------------------------------------------------------------------------------------------------------------------------

cd scalapack_installer_0.96

sudo ./setup.py --prefix=/opt/scalapack --mpibindir=/opt/mpich/bin --blacslib=/usr/lib/libblacs.a --blacsf77=/usr/lib/libblacsf77.a --blacsclib=/usr/lib/libblacsc.a --blaslib=/usr/lib/atlas/libblas.a --lapacklib=/usr/lib/atlas/liblapack.a

I got:

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

BLAS installation/verification

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

Checking if provided BLAS works... yes

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

Lapack installation/verification

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

Checking if provided LAPACK works... yes

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

BLACS installation/verification

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

Checking if provided BLACS works...

BLACS: provided BLACS cannot be used! aborting...

error is:

****************************************

/tmp/ccyk8TA3.o: In function `MAIN__':

tmpf.f:(.text+0x28): undefined reference to `blacs_pinfo_'

tmpf.f:(.text+0x4a): undefined reference to `blacs_get_'

tmpf.f:(.text+0x74): undefined reference to `blacs_gridinit_'

tmpf.f:(.text+0x7f): undefined reference to `blacs_gridexit_'

collect2: ld returned 1 exit status

------------------------------------------------------------------------------------------------------

Blas and Lapack seem to work well, but Blacs fails as it counters the 'undefined reference ' problem.

I have no idea how to solve it. Any help would be appreciated.
