CMake configuration error

[rdiarra]

Hi,

I'm trying to install hipfort on an AMD platform.

I get following error during CMake configuration step :

How can I resolve this problem ? Thank

I built hipfort with crayftn (ftn driver of CCE) and initially got the same error. The workaround was to give cmake the additional command line argument of -DHIPFORT_COMPILER_FLAGS="${YOUR_FAVORITE_FLAGS_HERE}". It would have been nice if the CMake error message "No compile flags were found" would have been followed by something like: You must specify the Fortran compiler flags to build hipfort with to cmake via '-DHIPFORT_COMPILER_FLAGS="..." ' , rather than leave the user guessing what flags cmake expects where for what purpose.

@rdiarra Please test with the latest ROCm 6.1.3. If issue is resolved, please close the ticket. Thanks!

@rdiarra Hi, have your issue been resolved? It seems to be a really odd issue based on your output. The problematic code https://github.com/ROCm/hipfort/blob/release/rocm-rel-6.0/cmake/Modules/SetFortranFlags.cmake#L83 suggest that dummy compilation tests are failing for the "-O0" flag. This is not normal and is likely problem or the environment e.g. file/dir permission of the ./build/CMakeFiles/CMakeTmp directory.

To debug, please try to following steps:

1. Create a dummy file with vi ./build/CMakeFiles/CMakeTmp/test.f90
2. Paste the following into the file; save and exit.

program dummyprog
  i = 5
end program dummyprog

3. Try to build the file with -O0 flag cd ./build/CMakeFiles/CMakeTmp && /opt/cray/pe/craype/2.7.13/bin/ftn -O0 ./test.f90

Report any error message you see.

Thanks!
