I managed to download a compatible openBLAS with conf

./configure --download-openblas --download-openblas-commit='0b678b19dc03f2a999d6e038814c4c50b9640a4e' --with-openmp --with-mpi=0 --with-shared-libraries=1 --with-mumps-serial=1 --download-mumps --download-metis --download-slepc --with-debugging=0 --with-scalar-type=real --with-x=0 COPTFLAGS='-O3' CXXOPTFLAGS='-O3' FOPTFLAGS='-O3';

--download-openblas-commit=<id> didn’t work by itself but with –download-openblas it did

case closed!

Subject: PETSc downloading older version of OpenBLAS

Hi all

During install I’m checking out an older version of PETSc (v3.17.1-512-g27c9ef7be8) but running into problems with –download-openblas in configure.

I suspect the newest version of OpenBLAS that is being downloaded from git is incompatible with this older version of petsc

Is there a way to have petsc –download an older version of openblas (eg. v0.3.20) ?

Thanks
