Building a cross-compiler for powerpc-eabi

Building a cross-compiler for powerpc-eabi

Hello there,

Can anyone tell me how to properly do this?
I tried this http://www.ifp.uiuc.edu/~nakazato/tips/xgcc.html
But it doesn't work using binutils 2.17, gcc 4.1.2 and newlib 1.15.0...


With kind regards
Timo Kerstan

   I suggest you create a combined source tree. This is easiest if you get
the sources using cvs and svn, because then binutils, gdb, newlib and the
simulator are already in a combined tree. But since you probably have the
source tarballs, try something like this:

	mkdir src
	cd src
	tar -jxf gcc-xxx.tar.bz2
	tar -jxf newlib-xxx.tar.bz2
	tar -jxf binutils-xxx.tar.bz2
	tar -jxf gdb-xxx.tar.bz2
	...
	mkdir combined
	cd combined
	ln -s ../gcc-xxx/* .
	ln -s ../newlib-xxx/*
	ln -s ../binutils-xxx/*
	ln -s ../gdb-xxx/*
	...
	cd ../..
	mkdir build
	cd build
	../src/combined/configure --target=powerpc-eabi --prefix=... \
	--with-newlib --enable-sim ...
	make
	make install

   There is some overlap (e.g. libiberty) between the source packages, and
normally you want to use what's in the gcc sources. But I've had a case
where libiberty from gcc was too old to compile binutils and then it should
be OK to use the one from the binutils instead.

   Btw, the target powerpc-eabisim defaults to a setup suitable for producing
binaries to run on the simulator.

   How do you know it doesn't work[1]?

Hi,

i did everything you described below an get the following message.  
I'm building the cross compiler on Mac OS X....

gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Werror -g -O2 -

make[2]: *** [all] Error 2

Right now i'm building binutils explicitly and will try to compile  
the rest as a combined tree...

Binutils built correctly and is working. I added it to the path...

First he complained about config.cache... He told me to remove it and  
run over....
Now there's a different problem compiling gcc, newlib and gdb as a  
combined tree... The make target all seems not to be defined in the  
libc folder of newlib...
I'm not very well known to make and that configure scripts....

Try configuring with --disable-nls, you won't have message
translations that way but the toolchain will build at least
(unless you hit some other problem...)

   You need to run make from the top level of your build tree, i.e. the same
directory in which you ran configure. Then Makefile will be created in each
directory as needed. I suggest you configure again with --disable-nls. I've
always used --disable-nls.

   And please don't top-post.

   It works for me with a combined tree. Here's exactly how I did:

Finally I found the problem.... It was the Apple make included in  
XCode 2.4.1. I Installed gmake 3.8.1 via Macports and everything now  
works fine...
