Error compiling ScaLAPACK with MSYS2/Mingw-w64/MS-MPI

[cyamin]

Hello,

I have successfully compiled LAPACK v3.5.0 using the mentioned configuration, using the included Makefiles and of course the necessary modifications to make.inc regarding the mingw-w64 compiler. I could not compile (for some reason) all the tests, but every test I managed to run, passed successfully.

Then I tried to compile ScaLAPACK v2.0.2 the same way, specifying similar compiler configuration and using the libmsmpi.a library created from msmpi.lib and msmpi.dll from the MS-MPI v7 package using the gendef-dlltool routine. Although the ScaLAPACK library seems to compile successfully, I get the following error in the BLACS testing part:

ScaLAPACK_compile_output.txt

(46.36 KiB) Downloaded 555 times

The errors are grouped in two: 'type mismatch(es)' and 'undefined reference(s)'. The same errors occur with MPICH2 so it is not down to MS-MPI.

If this attempt is successful, it would mean that compiling in Windows with mingw-w64 would be as simple as installing MSYS2 (with the necessary compiling packages) and using the linux Makefiles!

Any help would be greatly appreciated.

Costas

The undefined reference means he cannot find the MPI library
Did you try compiling a basic fortran MPI program?

Yes, I just did and it works as it should. I tried to post a more thorough post with attachments, but it gets flagged as spam.

Update:

I have managed to compile the BLACS tests just by addings $(LIBS) after ../../$(SCALAPACKLIB) in the /BLACS/TESTING/Makefile.

I have also run and passed all the double precision tests of ScaLAPACK. I believe you should add the MSYS2 as a compiling solution for LAPACK/ScaLAPACK in Windows/Mingw-w64. It works nearly out of the box.

That is a wonderful news!
Will do. And thanks for sharing.
