如何查看程序被哪个版本编译器编译的linux-gcc

那是不可能的，除非你加入了调试信息，也就是编译的时候加入了-g参数，然后用gdb调试就可以显示。最大程度上查看一个elf文件信息。

｛

readelf -Wa a.out | head
readelf -wi a.out
readelf -p .comment a.out
objdump -s --section .comment audioplayer

｝

如下：

[root@localhost rootfs]# readelf -Wa bin/gzip

How to retrieve the GCC version used to compile a given ELF executable? http://stackoverflow.com/questions/2387040/how-to-retrieve-the-gcc-version-used-to-compile-a-given-elf-executable

　　QUES: I'd like to retrieve the GCC version used to compile a given executable. I tried readelf but didn't get the information. Any thoughts?

　　ANS: To complete what others have said: it's not stored in the object (or exe) file, unless you compile with debugging information! (option -g). If you compile with debug info, you can get it back with readelf:　　

复制代码
[root@localhost test]# gcc a.c
[root@localhost test]# readelf -wi a.out
[root@localhost test]# gcc a.c -g
[root@localhost test]# readelf -wi a.out
The section .debug_info contains:
