Ich versuche, einen Fortran-Code mit f2py in eine gemeinsame Bibliothek zu importieren und in Python auf Windows 10 zu verwenden. (Es funktioniert gut auf meiner Linux-Partition .) Ich habe Anaconda installiert und mit conda install habe ich numpy, scipy, jupyter und matplotlib installiert, alles ohne Fehler. Ich benutzte Anaconda wieder, um Fortran-Compiler mit conda install mingw ohne Probleme zu installieren. Als ichf2py Fehler beim Erstellen Import-Bibliothek libpython27.a: kann die angegebene Datei nicht finden
python C:\Users\user_name\Anaconda2\Scripts\f2py.py -c --fcompiler=gnu95 --compiler=mingw32 -m foo foo.f
laufen bekomme ich folgende Ausgabe (Fehlermeldung am unteren Rand):

I Weg off-base sein könnte, aber es scheint mir, wie die Zusammenstellung gut geht, und Der Fehler tritt auf, wenn ein Python-Modul zusammengestellt werden soll. Die Datei C:\Users\user_name\Anaconda2\python27.dll existiert. Die Datei C:\Users\user_name\Anaconda2\libs\libpython27.a existiert nicht. Ich habe überprüft, dass ich Dateien im Ordner erstellen konnte (C:\Users\user_name\Anaconda2\libs\).
