Ubuntu - 链接 boost.python - 致命错误:找不到 pyconfi

问题描述

遇到一些问题，现在我已阅读以下内容:

Having some issues, now I have read the following:

hello world python 扩展在 C++ 中使用 boost?

我已经尝试将 boost 安装到我的桌面上，并且按照链接方面的建议完成.我有以下代码:

I have tried installing boost onto my desktop, and, done as the posts suggested in terms of linking. I have the following code:

#include <boost/python.hpp>
#include <Python.h>
using namespace boost::python;

现在我尝试与以下链接:

Now I have tried linking with the following:

g++ testing.cpp -I /usr/include/python2.7/pyconfig.h -L /usr/include/python2.7/Python.h
-lpython2.7

我也尝试了以下方法:

g++ testing.cpp -I /home/username/python/include/ -L /usr/include/python2.7/Python.h -lpython2.7

我不断收到以下错误:

/usr/include/boost/python/detail/wrap_python.hpp:50:23: fatal error: pyconfig.h: No such   
file or directory
# include <pyconfig.h>

我不知道我哪里出错了.我确实安装了 boost.python，只是链接有问题?

I don't know where I am going wrong. I do have boost.python installed, there's just a problem linking?

推荐答案

我刚遇到同样的错误，问题是 g++ 找不到 pyconfig.h(令人震惊，我知道).对我来说，这个文件位于 /usr/include/python2.7/pyconfig.h 所以附加 -I/usr/include/python2.7/ 应该修复它，或者，您可以使用以下命令将目录添加到您的路径中:

I just had the same error, the problem is g++ can't find pyconfig.h(shocking, I know). For me this file is located in /usr/include/python2.7/pyconfig.h so appending -I /usr/include/python2.7/ should fix it, alternatively you can add the directory to your path with:

export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:/usr/include/python2.7/"

您也可以将它添加到您的 .bashrc 中，它会在您下次启动 shell 时添加(您必须重新打开终端才能实现更改).

You can also add this to your .bashrc and it will be added whenever you start your shell next(you will have to reopen your terminal to realize the changes).

您可以使用 find/usr/include -name pyconfig.h 找到自己的 python 包含路径，在我的情况下返回:

You can find your own python include path by using find /usr/include -name pyconfig.h, in my case this returns:

/usr/include/python2.7/pyconfig.h
/usr/include/i386-linux-gnu/python2.7/pyconfig.h
