使用gdb针对C模块进行Python源调试
[英]Python source debugging with gdb for a C Module
问题描述
So I'm getting a SIGSEGV signal from my Python C Module. 
因此，我从Python C模块收到了SIGSEGV信号。 The module has been tested/built in Windows and now I'm attempting to use it under Linux (Linux Mint 17 64-bit). 该模块已在Windows中测试/构建，现在我正尝试在Linux（Linux Mint 17 64位）下使用它。 I'm very new to gdb but is there a way to get it to show Python's Source code? 我对gdb还是很陌生，但是有办法让它显示Python的源代码吗？
Program received signal SIGSEGV, Segmentation fault.

If you want gdb to show you the code in a file, you need to tell it where to look for the file. 如果希望gdb向您显示文件中的代码，则需要告诉它在哪里查找文件。
You can do this using the directory command followed by the path to the source files. 您可以使用directory命令执行此操作，后跟源文件的路径。
