用调试信息编译可执行文件？

Question

如何检查Linux可执行文件是否使用符号调试信息进行编译？

Answer 1

Quickest solution I can think of: Load it with GDB:

gdb myexecutable

You should get something like "(no debugging symbols found)" if there aren't any usable symbols inside.

Update: To return control to shell (or whatever) add --batch :

gdb myexecutable --batch

Answer 2

不确定，因为我现在正在使用OSX，但是如果它包含符号，则可能显示文件。
