There the issue indeed does not happen. When I switched to your CMake configuration line, I was able to reproduce the problem. The solution is to add `-fno-fortran-main` to the linker options via `CMAKE_SHARED_LINKER_FLAGS`. This will need PR https://github.com/llvm/llvm-project/pull/74139 land first. But this option will be a good way to control if the flang compiler should attempt linking in the `main` stub from its library. It seems like `flang-new` when being used as a linker with `-shared` included Fortran_main in the shared library. This seems wrong to me. The option `-fno-fortran-main` avoids this. I'm pondering if `-shared` is buggy here. It will require a bit more digging on my end to figure that out. https://github.com/llvm/llvm-project/pull/73124 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
