我正在尝试使用 libboost 库编译我的代码，方法是放入#include <boost/python.hpp>我的 C++ 代码。有人可以帮我正确的命令来运行它，尤其是包含和链接库。我在这方面很基础。

使用的命令（但不工作）：

g++ try.cpp -L /usr/lib/libboost_python.so -o try

编辑：

测试代码：

#include <boost/python.hpp>
#include <iostream>

int main() 
{

    std::cout << "Yes, it works :-)" << std::endl;

    return 0;
}

错误信息：

from try.cpp:1:
/usr/include/boost/python/enum.hpp:31: error: expected ‘;’ before ‘*’ token
/usr/include/boost/python/enum.hpp:32: error: expected ‘;’ before ‘(’ token

另一件事是，当我编译时g++ -Wall thread_one.cpp -o thread_one -lboost_thread，它可以使用 boost_thread 库。

尝试这个：

g++ try.cpp -o try -lboost_python

添加到您的编译器调用中也是一种很好的风格-W -Wall -Wextra -pedantic（这样您的下一个 SO 问题可以更具体:-)）。此外，-O2或者-O3用于优化可能是一个非常好的主意，尤其是对于 Boost。最后，当您有多个文件时，将构建拆分为单独的阶段可以更快地重新编译：

g++ -c -o try.o try.cpp -W -Wall -Wextra -pedantic -O2
g++ -o try try.o -s -lboost_python

最后，它正在工作。使用的命令如下：

g++ -I/usr/include/python2.6 try.cpp -o try -lboost_python -lpython2.6
