Preventing the addition of C-style comments in gfortran compilation 1

[Vahid9]

Hi,

I am compiling a code (VASP) using gfortran/openmpi. The codes includes about 50 files. When I issue "make", the compilation crashes because somehow the following lines get added to .f files.

And many more lines triggering all kinds of error. If I delete these C-style comments in the first file, the compilation moves to the next file and another crash.

Is there a way to stop the addition of these C-style comments to the process of compilation?

I do use the following flags for CPP

CPP_ = ./preprocess <$*.F | /cvmfs/soft.computecanada.ca/nix/var/nix/profiles/gcc-4.8.5/bin/cpp  -P -C -traditional >$*$(SUFFIX)

CPP   = $(CPP_) -DHOST=\"gfortran\"          -DMPI -DMPI_BLOCK=8000         -Duse_collective -DCACHE_SIZE=12000 -Davoidalloc -DNGZhalf         -DVASP2WANNIER90v2

Thank you,
Vahid

it seems that you need to use C preprocessor option [pre]-cpp[/pre]

Thanks for the link. In addition, I also added the tag "-nostdinc" to CPP. Now the code compiles.

Cheers,
