【问题描述】:
我通过 Homebrew 安装了 GDB 7.8.1 和 GCC 4.9。
当我打开一个由 GCC 编译的 (gcc-4.9 -g xxx.c -o xxx) 程序生成的核心文件时,它会报告:
→ gdb ./list_test /cores/core.1176

(no debugging symbols found)...done.
"/cores/core.1176": no core file handler recognizes format
我搜索了一下,发现有人建议使用 LLDB 而不是 GDB。
是否可以使用 GDB 调试核心文件?是不是因为 GDB 不支持 Yosemite 上的二进制格式?
