Scalapack linking error.

[vitruss]

Dear Scalapack/Lapack users!
I'm trying to compile Wien2k using ACML4.4.0 and gfortran with openmpi for SMP parallelization on Debian Squeeze AMD64 machine. I've compiled fftw2 and Scalapack (using installer) which are required. And now compiling Wien2k. During compilation the next problems appears:

You need more than -lscalapack -lblacs.
I need to add the blacsC for sure and also maybe the blacsF77 library in the linking sequence.

Please do not ask me why, but try

Code: Select all

-lblacsF77 -lblacsC -lblacs -lblacsF77 -lblacsC


instead of

Code: Select all

-lblacs -lblacsF77 -lblacsC

Thanks! It is compiled! I saw this "features" a couple of times, but never thought it can be used here.
