Ошибка при попытке обтекания с использованием f2py (минимальный рабочий пример)

Question

Я пытался запустить Minimum working example файл указан в:
https://docs.scipy.org/doc/numpy-dev/f2py/getting-started.html

После запуска следующей команды в Cygwin

python c:/Python27/Scripts/f2py.py -c fib1.f -m fib1 --compiler=mingw32

Команда завершается со следующей ошибкой:

error: Command "gcc -O2 -Wall -Wstrict-prototypes -DNPY_MINGW_USE_CUSTOM_MSVCR -D__MSVCRT_VERSION__=0x0900 -Ic:\cygwin\tmp\tmprggtye\src.win32-2.7 -IC:\Python27\lib\site-packages\numpy\core\include -IC:\Python27\include -IC:\Python27\PC -c c:\cygwin\tmp\tmprggtye\src.win32-2.7\fib1module.c -o c:\cygwin\tmp\tmprggtye\Release\cygwin\tmp\tmprggtye\src.win32-2.7\fib1module.o" failed with exit status 1

Я пролил много ссылок, пытаясь найти какое-то решение безрезультатно.
Буду благодарен, если кто-то может помочь мне с проблемой.
Я использую Windows 7 (64 бит) и Python 2.7.11.

Answer 1

Размещать то, что я сделал для потомков
Сразу после того, как опробовал вещи, упомянутые в комментариях и еще кое-что (не помню их всех), я попытался сделать следующее:

python c:/Python27/Scripts/f2py.py -c fib1.f -m fib1 --compiler=msvc --fcompiler==g77

g77 - готовый компилятор фортрана (любой другой компилятор фортрана должен работать).

Я закончил со следующими ошибками:

$ python c:/Python27/Scripts/f2py.py -c fib1.f -m fib1 --compiler=msvc  --fcompiler=g77

error: Unable to find vcvarsall.bat

Чтобы избавиться от последней ошибки, я черпал вдохновение из
1) ошибка: невозможно найти vcvarsall.bat
2) Как мне указать easy_install на vcvarsall.bat?

Я жестко закодировал местоположение vcvarsall.bat в C:/Python27/Lib/distutils/msvc9compiler в find_vcvarsall() функция в переменные toolsdir а также productdir в строках 245 и 249.

Я сделал это, так как установка переменной среды, как указано в 2 (выше), не работала.

Не может быть элегантным решением, но это сработало.
