Yeah --download-openblas-commit option is a modifier to --download-openblas - so both options should be specified.. There is a proposal to automatically enable --download-openblas when --download-openblas-commit (or other similar modifier) option is specified - but its not in petsc yet..

I managed to download a compatible openBLAS with conf

--download-openblas-commit=<id> didn't work by itself but with -download-openblas it did
case closed!

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
