在 f2py 中设置 fortran 编译器答案

【问题标题】：Setting the fortran compiler in f2py在 f2py 中设置 fortran 编译器
【发布时间】：2016-03-12 00:20:05
【问题描述】：

我正在尝试运行 f2py example 来创建已编译的扩展模块¶：

# 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

但是，代码不起作用。我相信这是因为它没有使用安装的编译器（操作系统是 ubuntu 12.04）。但是，尽管使用了“--fcompile”参数或更改了“CC”和“CXX”条目，它仍然无法正常工作......

这是完整的错误日志。请提供任何建议：

附： Iraf 是天文软件，不是编译器。

f2py -c --help-fcompiler 返回什么？查找“找到 Fortran 编译器”。
@unutbu 感谢您的关注我在编辑 3 中添加了结果
从命令行运行f2py -c --help-fcompiler会得到什么？是否有必要从 Python 脚本中运行 f2py ？或者您只是想以任何方式编译add 模块？
@unutbu 再次感谢：我可以将 f2py 作为 /usr/bin/f2py -c -m add add.f90 运行。这会生成 python 至少可以“导入添加”的 add.so。如果需要，我可以使用 popen 运行此命令。如果您添加回复，我可以将其设置为已接受

标签： python c compilation fortran f2py

【解决方案1】：

根据tutorial docs，使用 f2py 的一种简单方法是从命令行运行

f2py -c -m add add.f

这将创建模块文件add.so（或add.pyd，取决于您的操作系统），可以将其导入到Python脚本中

import add

如果add.so 位于sys.path 中列出的目录中。

【解决方案2】：

f2py 现在作为 numpy 的一部分进行维护。改变你的例子如下编译就好了。

# 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

非常感谢您的回复：我使用了您的导入，但仍然遇到非常相似的错误...它正在尝试使用 IRAF 脚本作为编译器。请问您有什么建议吗？我在问题中包含了新的错误消息
我从未使用过 IRAF，但从您的错误消息和网上查看，它似乎包含一个 Fortran 77 编译器，并且您的路径指向该编译器以编译 Fortran 77。因为您的程序可以使用更高版本的 Fortran 编译，尝试将 add.f 的扩展名从 .f 更改为 .f90。您将需要更改文件本身的扩展名以及 .py 文件中的引用。此外，为了使您编译的程序可用，我认为您需要对其进行一些更改，但也许在它至少可以编译之后在另一个问题中更好地解决。
再次感谢您的宝贵时间...我已经尝试了您的代码，但使用 f90 扩展名，我仍然遇到相同的错误...当我尝试提供编译器的完整地址时，有趣的是： --fcompiler = /usr/bin/gfortran 我收到错误：“不知道如何使用 '/usr/bin/gfortran' 编译器在平台 'posix' 上编译 Fortran 代码。” “警告：build_ext: f77_compiler=/usr/bin/gfortran 不可用。”
正如@unutbu 所发布的，您可以尝试替代（更简单）的编译方法。他的回答是我通常使用的方法。我应该早点指出这一点。
这是问题的间接解决方案，但感谢您和@unutbu，我至少可以运行 f2py。再次感谢 jthomas
