python - cryptopp 错误 : expected '=' , ',' 、 ';' 、 'asm' 或 '__attribute__' 在 '{' token 之前

Question

我添加了一个安全模块，需要安装 cryptopp，它是用 C 语言编写的，包含以下内容:

#include <Python.h>
#include <common/credentials.h>
#include "proto/security.pb.h"
#include <string.h>

我已经用 google 搜索了错误并验证了 Python.h header 存在，-I/usr/include/python2.6 显示在 make 中，python-devel-2.6.6-52.el6.x86_64软件包已安装。我缺少一面旗帜吗？是“命名空间”还是解析错误？

GCC 根据文件名的后缀决定文件使用什么语言编写。将文件重命名为 *.cc 或 *.cpp，或者将 -x c++ 传递给 g++。
