Original ticket http://projects.scipy.org/numpy/ticket/1043 on 2009-03-09 by trac user avi, assigned to unknown.

Hi,

I have added a new compiler -- pathscale -- and added it to numpy/distutils/fcompiler and edited init.py to add it to the list.

However when I run
% python setup.py config_fc

I get the pathscale compiler recognized but then the setup bypasses and continues and subsequently picks the gfortran, which I don't want.

When I added some verbosity to the above, I noticed this difference between pathscale and gfortran

% python setup.py -v config_fc

Running os.system('( /opt/pathscale/ice9_native_3.2n_B_sicortex/bin/pathf95 -v ; echo $? > /tmp/tmpoXv0XE/VCZd1T ) > /tmp/tmpoXv0XE/yNOdmp 2>&1')
_update_environment(...)
customize PGroupFCompiler
:

with gfortran..

Running os.system('( /.root0/usr/bin/gfortran --version ; echo $? > /tmp/tmpoXv0XE/xX3wVg ) > /tmp/tmpoXv0XE/tQhxpb 2>&1')
_update_environment(...)
exec_command(['/.root0/usr/bin/gfortran', '-Wall', '-ffixed-form', '-fno-second-underscore', '-fPIC', '-O3', '-funroll-loops', '-print-libgcc-file-name'],)
Retaining cwd: /.root0/net/home/avi/builds/numpy-1.2.1
_preserve_environment([])

So it seems to me that it is finding the pathscale compiler but skipping the exec_command.

Any help in resolving this appreciated. I am attaching the log file for the above script run and the pathscale.py files.

Other tidbits on system and os..

You should specify the compiler you want:

python setup.py build --fcompiler=pathscale

Replying to [comment:1 cdavid]:

You should specify the compiler you want:

{{{

}}}

I already tried it. Adding --fcompiler=pathscale did not make any difference .. here is a small snippet:

(sc1-m3n6:~/builds/numpy-1.2.1) avi% python setup.py config_fc --fcompiler=pathscale

:

If I can make the execution made by pathscale then the build process would work. In the current state it is bypassing pathscale and going straight to gfortran.

Avi, your pathscale configuration fails as the version pattern is wrongly configured returning None as the compiler version.

The version_pattern should read:

version_pattern =  r'PathScale\(TM\) Compiler Suite: Version (?P<version>[\d.]+)'

Attached are the files I used to build and install numpy with the PathScale compilers on my SiCortex machine. Replacing the init.py file and adding the pathf95.py file into the numpy/distutils/fcompiler folder enable functionality for the PathScale Fortran compilers. Replacing the ccompiler.py and adding the pathccompiler.py into the numpy/distutils/ enable functionality for the PathScale C/C++ compilers.

To build and install numpy with the pathscale compilers I used:

python setup.py build -v --compiler=pathcc --fcompiler=pathf95
python setup.py install

After installation f2py also recognized the pathf95 compiler.

Good Luck

RP
