Hi,

Currently, .f2py_f2cmap must be located in a directory where setup.py or f2py.py is called (to be exact, where numpy.f2py.capi_maps is imported). This location is hardcoded and there is no way to specify the file location within setup.py scripts.

However, you don't need to use .f2py_f2cmap file for specifying the correct mapping. Read the code in numpy/f2py/capi_maps.py and you'll find that inserting the following codelet to setup.py file might work (untested code):

from numpy.f2py.capi_maps import f2c_map
f2c_map['real'].update(sp='float', dp='double', qp='long_double')

HTH,
Pearu

Hello,

 

I am attempting to set up a numpy.distutils setup.py for a small python program that uses a Fortran module. Currently, the setup is able to compile and install the program seemingly successfully, but the f2py script erroneously maps the data types I am using to float, rather than double. I have the proper mapping set up in a .f2py_f2cmap in the source directory, but it does not seem to be copied to the build directory at compile time, and I cannot figure out how to make it get copied. Is there a simple way to do what I am trying to do? Alternatively, is there a way to specify the mapping in my setup.py scripts?

 

Here's a github repo with the project:
