I installed CDT using eclipse for linux platform. When I create new project I see the default compiler option is GNU toolchain. The project which I'm working on requires different cross compiler which is present on that linux machine. I tried substituting the "Conpiler Invocation command" in project-->properties-->C/C++ Build-->Discovery Options. But it doesn;t seem to be replacing the default GNU compiler.
Can someone please give me pointers on changing the GNU toolchain to desired one?
