RHEL/Rocky 9 build issue

[mattperini]

Has an effort been made to support RHEL/Rocky 9? I built it and discovered that the blas-3.9.0-10.el9.x86_64 rpm is built with a default integer size of 64. That's not compatible with the BLAS interface in Dakota, so I had to build LAPACK/BLAS from source with a 32-bit integer size and point the CMAKE configuration at it.

Is there a better way?

I ran into the same issue and installed the atlas-devel package, which provides blas and lapack. The RHEL9 release notes say atlas-devel is part of the AppStream repo.

Thank you for the confirmation. The atlas-devel package doesn’t have libblas and liblapack libraries as such. Which libraries did you point cmake at for the build? Matt From: J.

I should have added that detail. You need to link to libatlas.so. In my cmake command I include:

-DBLAS_LIBS=/usr/lib64/atlas/libsatlas.so -DLAPACK_LIBS=/usr/lib64/atlas/libsatlas.so 

If you are using a CMake cache file, you can add:

set(BLAS_LIBS "/usr/lib64/atlas/libsatlas.so" CACHE FILEPATH "atlas blas/lapack lib")
set(LAPACK_LIBS "/usr/lib64/atlas/libsatlas.so" CACHE FILEPATH "atlas blas/lapack lib")

That’s perfect. Thanks Matt From: J.
