Unable to compile berkeleygw@2.1 on a powerpc machine

[Ashwin Kumar k]

I am trying to compile  berkeleygw@2.1 on a powerpc ()

But I end up getting the following error during compilation, 

```

$spack_root/lib/spack/env/gcc/gfortran -ffree-form -ffree-line-length-none -fno-second-underscore -fallow-argument-mismatch -I ./Common -I $spack_root/opt/spack/linux-debian11-power8le/gcc-11.3.0/fftw-3.3.10-aorzxrzqxxd6sk4yur4dmn5qixz2zg6s/include -I $spack_root/opt/spack/linux-debian11-power8le/gcc-11.3.0/hdf5-1.12.2-2k7sveybjzcx7ok7w5owchkdaib2gbcn/include -c -fopenmp Common/typedefs.p.f -o Common/typedefs.o -J Common/

```

does anyone know what the solution might be?

Thanks in advance

Hi Ashwin, 

Check the FCPP flags, try maybe using: "FCPP    = cpp  -P -ansi  -nostdinc  -C  -E  -std=c11" in arch.mk

Thanks a lot for your help!

Would you have any suggestions on which other FCPP flags I could check for, or what might be causing the issue?

The flags you suggested don't seem to work:

```

$ grep "FCPP"  arch.mk

FCPP    = cpp  -P -ansi  -nostdinc  -C  -E  -std=c11

$ tail -n 12 spack-build-out.txt

Dear Ashwin,

 

Please verify that the FCPP line you gave was actually used, i.e. that it appears in that build log. The snippets you gave do not show whether it got used or not.

 

Best,

David
