Potential issue with CMake 3.22.5 / GNU 12.3.0 / OpenMPI 5.0.3 about incompact3d

Hello, I think you just need to export FC=mpif90 before running cmake. Regards, mathrack May 24, 2024 20:21:00 Gaurav Gupta ***@***.***>:

*Describe the bug* The build using CMake version 3.22.5 with GNU 12.3.0 and OpenMPI 5.0.3 fails on our HPC with the following error, * 7 | use mpi | 1 Fatal Error: Cannot read module file ‘/home/apps/openmpi/5.0.3/install/lib/mpi.mod’ opened at (1), because it was created by a different version of GNU Fortran compilation terminated. gmake[5]: *** [src/CMakeFiles/decomp2d.dir/decomp_2d_constants.f90.o] Error 1 gmake[4]: *** [src/CMakeFiles/decomp2d.dir/all] Error 2 gmake[3]: *** [all] Error 2 gmake[2]: *** [downloadBuild2decomp-prefix/src/downloadBuild2decomp-stamp/downloadBuild2decomp-build] Error 2 gmake[1]: *** [CMakeFiles/downloadBuild2decomp.dir/all] Error 2 gmake: *** [all] Error 2 CMake Error at cmake/FindDECOMP2D.cmake:22 (message): Build step for 2decomp-fft failed: 2 Call Stack (most recent call first): CMakeLists.txt:46 (find_package) * *To Reproduce* Steps to reproduce the behavior: 1.

I tried it but no help. The issue persists.

Fatal Error: Cannot read module file ‘/home/apps/openmpi/5.0.3/install/lib/mpi.mod’ opened at (1), because it was created by a different version of GNU Fortran

This implies you've changed your Fortran compiler version without rebuilding MPI

[mathrack]

I have changed the title of the issue : the latest version of the code can be compiled without issues on various HPC systems.

I think the present issue is connected with the softwares installed on a specific cluster and not with incompact3d. I will close the issue.

Feel free to comment and provide more details (build environment / build commands / ...)
