[Numpy-discussion] compile fortran from python
Hello list,
on compiling some F95 code into a library I got following message:
Warning: Nonconforming tab character at (1)
i figured out it is because setup uses default compiler flags. this is
my set-up command
python setup.py config_fc --fcompiler=gnu95 install --home=./tbuild
I tried to pass -ffree-form flag to the setup using build_info parameter
config.add_library('hm1d', sources = ['src/hm1d.f95'], build_info =
{'extra_compiler_args':'-ffree-form'})
but is still get the warnings.
the setup does not seem to receive these flags or it is ignoring them.
Any hints?
Cheers

Hi,
You can create a setup.py file containing
def configuration(parent_package='',top_path=None):
from numpy.distutils.misc_util import Configuration
config = Configuration(None,parent_package,top_path)
config.add_library('flib', sources = [test.f95])
config.add_extension('ctest', sources = ['ctest.c'],
libraries=['flib'])
return config
if __name__ == "__main__":
from numpy.distutils.core import setup
setup(configuration=configuration)
#eof
Running
python setup.py config_fc --fcompiler=gnu95 build
will build a Fortran library flib.a and link it to
an extension module ctest.so. Use build_ext --inplace
if ctest.so should end up in current working directory.
Is that what you wanted to achieve?
HTH,
Pearu

Your command above has a problem because you use gcc to build fortran code - you should use the gfortran compiler instead. cheers, David ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

I would like to compile some Fortran code using python, build a shared library, and link to it using python. But I get a message saying the compiler does not recognise the extension of my file. this is my command: gcc -fPIC -c -shared -fno-underscoring test.f95 -o ./lib/libctest.so.1.0 what is the easiest method to achieve this? I suspect I could create a custom extension and customise the unixccompiler object or could I just use the compiler object defined by f2py(fcompiler).
