Re: Reg : Powerpc 750 gcc cross compiler Doubt

I have a project that I would like to build with powerpc750 gcc cross

"/opt/crosstool/gcc-4.0.1-glibc-2.3.5/powerpc-750-linux-gnu/bin/powerpc-750-linux-gnu-gcc
-static bubble.c -o bubble"

But if  I have a project to built by powerpc which has files scattered
around that need to be included and things being set in the makefile
and other files.
writing down implicitly on the command line is one solution i guess,
I mean the includes and then the plugging in the object files that are
needed by the main file. Is there a way around this like configuring
with the target architecture(powerpc).
Please excuse me for bothering you but I am new to linux and also to
crosscompiling.

The usual thing to do is set CC to the compiler, then ignore the fact that you're using a crosscompiler. This usually just works, assuming you're using a modern build system.

http://www.ailis.de/~k/docs/crosscompiling/
has some notes about how to crosscompile a few common libraries
(along with some outdated notes about how to build a crosscompiler).

You might also look at frameworks that make crosscompiling standard
packages easy, e.g. ptxdist, buildroot, or familiar.
