Python error(1):error: command 'gcc' failed with exit status 1

用Python编译c++项目的时候遇到“command 'gcc' failed with exit status 1”错误。

下载和更新python-dev等没有解决问题依旧报错。

终端错误详细代码如下：

发现错误是我自己c++的版本过低导致gcc编译报错。解决办法：

修改了代码中调用ofstream obj_file(filename)的地方，改成ofstream obj_file(filename.c_str()) 问题解决。

怎么找代码中调用的地方，我是直接把#include 屏蔽掉，然后编译程序，程序会报错，然后就直接修改。

完毕。
