Thank you Matt I'll try this and let you know.

I can compile PETSc in debug mode with this configure and make lines. I can run the PETSC tests, which seem fine. When I compile the library in optimized mode, either using -O3 or O1, for example configuring with: I hate to yell "compiler bug" when this happens, but it sure seems like one. Can you just use --with-debugging=0 without the custom COPTFLAGS, CXXOPTFLAGS, FOPTFLAGS? If that works, it is almost certainly a compiler bug. If not, then we can go in the debugger and see what is failing. Thanks, Matt $ ./configure --prefix=/opt/petsc-oneapi22u3 --with-blaslapack-dir=/opt/intel/oneapi/mkl/2022.2.1 COPTFLAGS='-m64 -O1 -g -diag-disable=10441' CXXOPTFLAGS='-m64 -O1 -g -diag-disable=10441' FOPTFLAGS='-m64 -O1 -g' LDFLAGS='-m64' --with-debugging=0 --with-shared-libraries=0 --download-make and using mpicc (icc), mpif90 (ifort) from Open MPI, the static lib compiles.

Any help is mostly appreciated, I'm starting to work with PETSc. Our plan is to use the linear solver from PETSc for the Poisson equation on our numerical scheme and test this on a GPU cluster. So also, any guideline on how to interface PETSc with a fortran code and personal experience is also most appreciated!
