“未剥离"；但是“没有调试符号" [英] "not stripped" but "no debug symbols"

问题描述

您能解释一下不同的结果吗?

Can you explain the different results:

$ file libc-2.8.so
libc-2.8.so: ELF 32-bit MSB shared object, PowerPC or cisco 4500, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.10, with unknown capability 0x41000000 = 0x13676e75, with unknown capability 0x10000 = 0xb0401, not stripped

请注意最后的未剥离".

Notice the "not stripped" at the end.

和

(gdb) file libc-2.8.so
Reading symbols from /opt/Cross_Tools/powerpc-linux-gnu/powerpc-linux-gnu/libc/lib/libc-2.8.so...(no debugging symbols found)...done.

注意(未找到调试符号)"

Notice the "(no debugging symbols found)"

推荐答案

您通常必须在调试模式下进行编译(

You typically have to compile in debug mode (-g is the GCC command-line option) to include the debug symbols, it's not as if they're always there until stripped out. The default is to build in non-debug mode, without the symbols.
