Scalapack Installer with PGI compilers

[mwaldron]

I have successfully run the Scalapack installer v0.91 using Intel compilers with MPICH. I am now trying to do the same with PGI compilers, but am getting the following error:

setup.py --mpibindir=/afs/isis/pkg/mpich/pgi/bin --mpiincdir=/afs/isis/pkg/mpich/pgi/include --downblacs --downblas --downlapack --mpicc=mpicc --mpif77=mpif77

It appears that the framework.py script is unable to detect the PGI compilers. Is there a workaround for this?

Hello Mike,
actually it was a pretty easy problem to solve (intel compilers have exactly the same). The reason it was not addressed was that I didn't have access to any PGI compiler. Please use the attached version of the installer. The file on the LAPACK website will be updated as soon as possible.
Thanks for informing us about this

Alfredo,
Thanks for providing the updated installer. That worked just great. I did have one problem though. I got the following error when it was compiling the scalapack test routines...

Hello Mike,
apparently PGI compilers require different options when a C main program is linked to Fortran subroutines and vice-versa. I fixed this now (new version attached). However, the package I sent you yesterday was correctly compiling all the library just failing on the test programs.
Your feedback is very precious for us.
Thanks a lot

Alfredo

Alfredo,

Your latest update fixed the tester compile problem. The entire install ran without error.

Thanks again.

I tried the latest scalapack_installer.tgz from the website and the two archives posted by Alfredo and I get the same error. I'm running it on Scientific Linux SL release 5.3 (Boron).
Using also the " --fcflags=-nofor_main" did not change anything.
