Compile kernel for Sarge in Etch!?

Moloko · 06-01-2006, 11:41 AM

I'm running Etch now, but my server is still Sarge. Can I still compile kernels on Etch for Sarge even though the default gcc compiler is different? If not, how do I tell make-kpkg to use a different gcc version?

Correct me if I'm mistaken, but isn't Sarge 32bit and Etch 64bit? If so, the compiler shouldn't matter. When you do menuconfig, select the option (probably under Processor Type and Features) for 32bit instead of 64bit.

You are mistaken

The default gcc compiler is different for Etch, I just need a hint on how to use an older gcc compiler with make-kpkg to make sure the kernel works for Sarge.

Refrased: can I use a kernel on Sarge that is compiled on Etch with gcc-4 ???

Yes, but any modules you are using must be compiled using same version of gcc on the etch system or they will not work. Safest bet is to use the gcc version for sarge.

About make-kpkg using different versions of gcc (this will also work for different compilers): first off you need to install the version you want to use. For example using gcc-x.y. Install it the standard way with apt-get install gcc-x.y (as you well know, but if any newbies read this...)

Now in theory typing

Code:

MAKEFLAGS="CC=gcc-x.y" make-kpkg ...etc.etc...

should get the job done.

Use export CC=/usr/bin/gcc-3.3 which should be the default compiler in Sarge and you have it installed in the console/console window where you will compile. I doubt that it will make a difference though which compiler you use as long as you will not be compiling kernel modules on the Sarge machine.

Thanks guys! I couldn't find much with Google on this, but that's what I needed to know
