Installing on OS X 10.9 fails

[mtodd]

The linker fails due to this error:

Undefined symbols for architecture x86_64

Here's a snippet of the log including the lengthy list of symbols omitted for the architecture: https://gist.github.com/mtodd/ca1ea8b7851207c498e7

I know the README/installation instructions advises that you have not tried to install this on Mac OS X, but I thought I'd let you know that I tried and failed. Python and Fortran are pretty far outside my comfort/familiarity zone (so no real surprise) but I'm happy to dig in if you have the time.

Thanks for reporting the issue. This seems to be a linking issue with f2py on Mac. Can you post the output of the following command (run from a shell not from the python interpreter):

f2py -c --help-fcompiler

also, can you try building the fortran module manually (again from a shell) by running

LDFLAGS='-Wall -undefined dynamic_lookup -bundle' f2py -m libforbdf -c --fcompiler='gnu95' --f90flags=-ffixed-line-length-none libforbdf.f95 

inside the pybdf directory

[mtodd]

Here's the output from f2py2.7 (I don't have a binary called f2py): https://gist.github.com/mtodd/ddfc9125b6a33c769f3c

And the output running the build command from the leftover pip install dir: https://gist.github.com/mtodd/25a2cbd60e759215cfb3

Seems to have succeeded...

pybdf $ python

>>> import libforbdf
>>> libforbdf
<module 'libforbdf' from 'libforbdf.so'>
>>> libforbdf.read_channels
<fortran object>
>>> 

That's from the pip install directory. Need to actually finish installing it to get it globally accessible still, assuming this is really working. Will give it a closer look in a bit.

good seems to be working, now we need to find a way to put those ldflags in the setup.py file, so that the package can build, could you try changing the following (in setup.py):

ext1 = Extension(name = 'libforbdf',
                 sources = ['libforbdf.f95'])

to

ext1 = Extension(name = 'libforbdf',
                 sources = ['libforbdf.f95'],
                 extra_compile_args=['-Wall', '-undefined', 'dynamic_lookup', '-bundle'])

and if that doesn't work, to:

ext1 = Extension(name = 'libforbdf',
             sources = ['libforbdf.f95'],
             extra_link_args=['-Wall', '-undefined', 'dynamic_lookup', '-bundle'])

and then try to install the package with

python setup.py install
