Complie Boost.Python code error: library not found for -lpython3.6m

Question

我有一个示例代码Boost.Python

#include <boost/python.hpp>

char const* greet()
{
    return "hello, world";
}

BOOST_PYTHON_MODULE(hello_ext)
        {
                using namespace boost::python;
                def("greet", greet);
        }

我编译它时指定 Python3

g++ -o hello_ext.so -O2 hello.cpp -std=c++11 -fPIC -shared \
-Wall -Wextra `python3.6m-config --includes --libs` \ 
-lboost_python3

但是我得到了错误

ld: library not found for -lpython3.6m
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Python：Python3.6 /Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 Boost.Python：使用brew install boost-python --with-python3

安装

python3.6m-config --includes --libs的输出是

-I/Library/Frameworks/Python.framework/Versions/3.6/include/python3.6m -I/Library/Frameworks/Python.framework/Versions/3.6/include/python3.6m
-lpython3.6m -ldl -framework CoreFoundation

如何通过指定 python3 和 boost.python3 来编译我的代码？

Answer 1

检查 python3.6m-config --ldflags 提供的目录，确保 libpython3.6m.dylib 在那里。如果是这样，请将上述命令的选项添加到您的编译器调用中。

如果不存在，您需要使用 --enable-shared 构建 Python。
