Anything particular you have in mind here?

[milancurcic]

Yes. If you have access to either Cray (ftn) or IBM (xlf90) Fortran compiler suites, the goal is to confirm that functional-fortran compiles and passes unit tests, i.e.:

git clone https://github.com/wavebitscientific/functional-fortran
cd functional-fortran
cmake .
make
ctest

[milancurcic]

@boegel Thanks! It looks like we just need to add the Cray compiler definition in CMakeLists.txt (currently only Intel and GNU are there). I will follow-up on this.

[milancurcic]

cmake build rules for Cray ftn are now part of the master branch. However, FC needs to be specified when issuing cmake, e.g. FC=ftn cmake ...

I had chance to try building this with Cray Fortran 8.5.1 and the compiler spends about ~hour building before it fails with the message:

$ make
Scanning dependencies of target functional

make[1]: *** [CMakeFiles/functional.dir/all] Error 2
make: *** [all] Error 2

More later.

I can reproduce the above issue with crayftn-8.5.6.
