我试图用来pycparser
解析这个 C 代码:
带有最小示例和 Makefile 的 repo 在这里:
https://github.com/nbeaver/pycparser-problem
在 Debian Jessie 上使用pycparser
v2.14(来自 pip)和 gcc 4.9.2。
我尝试过的事情:
-nostdinc
将标志传递到gcc
并包含该fake_libc_include
文件夹。- 用于
-D'__attribute__(x)='
取出 GCC 扩展 - 使用假标题,例如
<sys/param.h>
-std=c99
如果代码与 C99 不兼容,请使用。- 重现redis 示例,以防我的机器出现异常情况。
这是回溯的样子:

回溯指向这一行:
这又指向这个#define
