Hi, Up to now, I have managed to build Fortran extensions with f2py by ussing the following command: $ python setup.py config_fc --fcompiler=gnu95 --f77flags='-fmy_flags' --f90flags='-fmy_flags' build
I think that these options should be able to go in a setup.py file, and use the f2py_options file. One way of doing this is to extend sys.argv with the required command line options: import sys sys.argv.extend ( ['config_fc', '--fcompiler=gnu95', '--f77flags="-fmy_flags"', "--f90flags='-fmy_flags"] ) This works well if all the extensions require the same flags. In my case, however, One of the extensions requires a different set of flags (in particular, it requires that flag -fdefault-real-8 isn't set, which is required by the extensions). I tried setting the f2py_options in the add_extension method call: config.add_extension( 'my_extension', sources = my_sources, f2py_options=['f77flags="-ffixed-line-length-0" -fdefault-real-8', 'f90flags="-fdefault-real-8"'] ) This compiles the extensions (using the two dashes in front of the f2py option eg --f77flags results in an unrecognised option), but the f2p_options goes unheeded. Here's the relevant bit of the output from python setup.py build: compiling Fortran sources Fortran f77 compiler: /usr/bin/gfortran -ffixed-line-length-0 -fPIC -O3 -march=native Fortran f90 compiler: /usr/bin/gfortran -ffixed-line-length-0 -fPIC -O3 -march=native Fortran fix compiler: /usr/bin/gfortran -Wall -ffixed-form -fno-second-underscore -ffixed-line-length-0 -fPIC -O3 -march=native compile options: '-Ibuild/src.linux-i686-2.7 -I/usr/lib/pymodules/python2.7/numpy/core/include -I/usr/include/python2.7 -c' extra options: '-Jbuild/temp.linux-i686-2.7/my_dir -Ibuild/temp.linux-i686-2.7/my_dir' How can I disable (or enable) one option for compiling one particular extension? Thanks! Jose
