Question

我在将c ++代码添加到我的c ++代码中时遇到了问题，这些代码使用＆＃39; swig＆＃39;进行编译。我想将c ++作为我的python东西的后端。

调用这两个命令

swig -c++ -python spherical_overlap.i
python setup.py build_ext --inplace

后者给我以下错误

clang: warning: -lboost_system : 'linker' input unused
In file included from spherical_overlap_wrap.cxx:3427:
./spherical_overlap.h:8:10: fatal error: 'boost/math/special_functions/bessel.hpp' file not found
#include <boost/math/special_functions/bessel.hpp>

该文件位于那里。我想我必须为编译器设置以下标志

-I /usr/local/include

问题是，我不知道该怎么做。这是我的＆＃39; setup.py＆＃39;文件

#!/usr/bin/env python

from distutils.core import setup, Extension


spherical_overlap_module = Extension('_spherical_overlap',
                           sources=['spherical_overlap_wrap.cxx', 'spherical_overlap.cpp'],
                           swig_opts=['-c++', '-py3'],
                           extra_compile_args =['-lboost_system '],
                           )

setup (name = 'spherical_overlap',
       version = '0.1',
       author      = "SWIG Docs",
       description = """Simple swig spherical_overlap from docs""",
       ext_modules = [spherical_overlap_module],
       py_modules = ["spherical_overlap"],
       )

您可以执行以下任一操作：

将include_dirs = ['/usr/local/include'],添加到Extension构造函数调用

将以下内容添加到文件setup.cfg：

[build_ext]
include-dirs = /usr/local/include

指定include-dirs命令的build_ext选项，即运行

python setup.py build_ext --inplace --include-dirs /usr/local/include

将-I/usr/local/include添加到CPPFLAGS环境变量，例如，运行
```
CPPFLAGS="-I/usr/local/include" python setup.py build_ext --inplace
```

可能第二种方式是首选方式，因为它反映了取决于本地系统配置的选项。

使用swig和python设置编译器标志
