Linux Find Out GNU gcc Compiler Version Used To Compile Running Kernel

Posted on in Categories last updated February 23, 2012

I‘ve multiple version of gcc installed on my systems as follows:

ls -l /usr/bin/gcc*
lrwxrwxrwx 1 root root 7 Jan 11 05:20 /usr/bin/gcc -> gcc-4.4
-rwxr-xr-x 1 root root 239528 Sep 21 2010 /usr/bin/gcc-4.3
-rwxr-xr-x 1 root root 255536 Nov 15 2010 /usr/bin/gcc-4.4

I need to build a nvidia device driver using the same version of GNU compiler as was used to compile the currently running kernel. How do I find out the version of my GNU gcc compiler that was used by upstream Linux distribution to compile and pack my binary Linux kernel?

Q. I’ve a c program and I’d like to run in Linux.

A. C program need to compile and run in Linux using cc or gcc command. When you invoke GCC (GNU C Compiler), it normally does preprocessing, compilation, assembly and linking for you. For example to compile hello.c program , type the following command:
cc -o hello hello.c
OR
gcc -o hello hello.c

It will compile and produced an exectuable file called hello. To run program type:
./hello
