Установка компилятора Фортрана в f2py

Question

Я пытаюсь запустить f2py example создать скомпилированный расширение module¶:

# import os 
# os.environ["CC"] = "gcc" 
# os.environ["CXX"] = "g++" 

# Using post-0.2.2 scipy_distutils to display fortran compilers 
from scipy_distutils.fcompiler import new_fcompiler 
compiler = new_fcompiler() # or new_fcompiler(compiler='intel') 
compiler.dump_properties() 

#Generate add.f wrapper 
from numpy import f2py 
with open("add.f") as sourcefile: 
    sourcecode = sourcefile.read() 
    print 'Fortran code' 
    print sourcecode 

# f2py.compile(sourcecode, modulename='add', extra_args = '--compiler=gnu --fcompiler=gnu') 
f2py.compile(sourcecode, modulename='add', extra_args = '--fcompiler=gfortran') 
# f2py.compile(sourcecode, modulename='add') 

import add 

Однако код не работает. Я считаю, что это потому, что он не использует установленный компилятор (оперативная система - ubuntu 12.04). Однако, несмотря на использование аргумента «-fcompile» или изменение записей «CC» и «CXX», он все еще не работает.

Это полный журнал ошибок. Важные замечания:

P.S. Ираф - это астрономическое программное обеспечение, а не компилятор.

Answer 1

Пер с tutorial docs, простой способ использовать f2py, чтобы запустить из командной строки

f2py -c -m add add.f 

Это создает файл модуля add.so (или add.pyd, в зависимости от вашей операционной системы), которая может быть импортировано в сценарий Python с

import add 

при условии add.so находится в директории, указанной в sys.path.

Answer 2

f2py теперь поддерживается как часть numpy. Изменение вашего примера следующим образом компилируется просто отлично.

# import os 
# os.environ["CC"] = "gcc" 
# os.environ["CXX"] = "g++" 

# Using post-0.2.2 scipy_distutils to display fortran compilers 
from numpy.distutils.fcompiler import new_fcompiler 
compiler = new_fcompiler() # or new_fcompiler(compiler='intel') 
compiler.dump_properties() 

#Generate add.f wrapper 
from numpy import f2py 
with open("add.f") as sourcefile: 
    sourcecode = sourcefile.read() 
    print 'Fortran code' 
    print sourcecode 

# f2py.compile(sourcecode, modulename='add', extra_args = '--compiler=gnu --fcompiler=g$ 
f2py.compile(sourcecode, modulename='add', extra_args = '--fcompiler=gfortran') 
# f2py.compile(sourcecode, modulename='add') 

import add
