问题
I'm attempting to build a Python extension from Fortran source using Numpy's f2py.py
script. I'm following the steps from http://www.scipy.org/F2PY_Windows (web archive). My system is Windows 7 64-bit, and I primarily use Python 2.7.3 [MSC v.1500 64 bit (AMD64)]. I have Numpy-MKL 1.7.1, from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
Here is what I've tried:
- Choose a Fortran compiler. Since I'm using 64-bit Python, a 64-bit Fortran compiler is required. From MinGW-w64, I've tried a few of the personal builds.
- Open a new
cmd.exe
shell, and edit the path to where I extracted the GCC compilers, i.e.:set PATH=%PATH%;c:\gnu\mingw64\bin
set C_INCLUDE_PATH=C:\gnu\mingw64\include
Try the
f2py.py
build with this command:C:\Python27\python.exe C:\Python27\Scripts\f2py.py -c --fcompiler=gnu95 --compiler=mingw32 -lmsvcr90 -m foo foo.f90
The output is (removing noise lines at <--snip-->
):

Note that the first time this is run, three new files are build in C:\Python27\libs
:
libmsvcr90.a
libpython27.a
python27.def
Do I need to install anything else? Do I need to provide other options to f2py
? More generally speaking, it possible to build an extension for MSVC-build Python from GNU compilers?
回答1:
It seems that the solution is to just comment out the exception line. See this blog post.
回答2:
I had the similar error when trying to install ggplot with
pip install -U ggplot
The solution was found here: https://github.com/obspy/obspy/wiki/Installation-via-Anaconda
Anaconda for Windows ships with C and Fortran compilers, however compiling on a 64bit Windows may require a small patch by changing line no. 331 in AnacondaInstallDir\Lib\site-packages\numpy\distutils\fcompiler\gnu.py to pass #raise NotImplementedError("Only MS compiler supported with gfortran on win64").
回答3:
This should be fixed in a future release, a discussed and changed.
It looks like this change did not make it to the 1.9.x maintenance branch, but in the master tree and whatever version is after.
