Hi,

I am having to port linux to a new architecture. This architecture does not
have gcc ported on to it. This does have an ansi c compiler/as/ld.

Has anyone has had any experience/success with building linux with an ansi c
compiler. I know it does not build automagically, but any info on
deviations/changes/tools would be appreciated a LOT.

thanks in advance,
dominique

Well, the Linux kernel highly depends on some GCC extensions, so you'll
need to make gcc work for your architecture (btw., what arch are you
working on?).

With a lot of luck, Intels compiler (icc) may also produce a working
kernel image, but it'll probably only work for ia32 and ia64 :)

You'd need to work around a lot of gccisms for the Linux kernel. ...and
GNU userland may not easily build with other compilers, too...

to compile the linux kernel only a 'simple' gcc/binutil
version is required ... so the best thing would be to
port just the required parts of gcc/binutils

see here for some details:
http://vserver.13thfloor.at/Stuff/Cross/howto.info

(make sure to compile and install the binutils first)

HTH,
Herbert

PS: I doubt that an ansi compiler (probably not even
    C99) will be able to compile linux kernels ...
PPS: please let me know if you succeed ...
