如何检查程序是否使用调试符号编译？
问题描述：
我想在GIMP中跟踪一些代码，因此需要启用调试符号的GIMP。我不记得我是否在编译期间启用了它们。
I'd like to trace some code in GIMP and therefore need GIMP with debug symbols enabled. I don't remember whether I have enabled them during compilation. How to check that without recompiling the program?

可以使用文件和 objdump 。特别是，你可以看看文件是剥离还是未剥离，以及 objdump --syms 输出有用的东西（对我来说， for a regular build）。
You can use file and objdump on Linux. In particular, you can look at whether file says "stripped" or "not stripped", and whether objdump --syms outputs anything useful (for me, it says "no symbols" for a regular build).
