Send the output from otool -L libdeal_II.g.9.3.0.dylib otool -L libslepc.3.15.dylib otool -L libpetsc.3.15.dylib You will need to find the directories of these libraries and include them in the otool command.

Hello,

I tried to run Step-17 in Dealii, a PETSc Dependenant software, but I got the following error. Given I have two versions of PETSc. I use the other one for another software.

I googled and found that the issue is solved by commenting out the line "ADD_FLAGS(DEAL_II_LINKER_FLAGS "-fuse-ld=gold")" in "cmake/checks/check_01_compiler_features.cmake", make test, worked. --- https://groups.google.com/u/1/g/dealii/c/JxUOyd_4eFM?pli=1https://groups.goo... <https://groups.google.com/u/1/g/dealii/c/JxUOyd_4eFM?pli=1https://groups.google.com/u/1/g/dealii/c/JxUOyd_4eFM?pli=1> ---

Any suggestions for how to get around that error "PETSc Error --- Application was linked against both OpenMPI and MPICH based MPI libraries and will not run correctly" in the new version of DealII.9.3 as I could not find a .cmake similar file to edit?

Thanks in advance! Ahmed
