Disable execstack while compiling a specific program

Hi Guys,

I would like to disable the Linux feature "kernel.exec-shield" for a particular program while compiling it.I have tried the following and it doesn't seem to help.(Note:I do not want to do this at the kernel level,but for that specific compiled code)

setarch i386 <program>
gcc -ggdb3 -o <output> -Wa,--noexecstack <source_code>

Can anyone tell,how to achieve this?

Kernel version:2.6.9-55

Its a kernel feature. You have to disable it at the "kernel level". You could run a system command from the app, running as root, to echo something to whatever /proc does the exec-shield stuff.

You can try like this:
"gcc -g -o test test.c -z execstack",means add "-z execstack",you can "man ld" to see more.
