uclibc toolchain HOWTO

[Francois-Rene Rideau]

Dear Dave,

here is a brief HOWTO, that you may include in the toolchain page of our site.
It isn't tested, so maybe you can test it first. :-)

We recommend that you use the uclibc toolchain
	http://uclibc.org/toolchains.html
for building the kernel and kernel modules.

Here is how you do it:
	mkdir -p /usr/src/j820/uclibc
	cd /usr/src/j820/uclibc
	wget http://uclibc.org/cgi-bin/cvsweb/toolchain/gcc-3.3.x.tar.gz?view=tar
	tar zxf gcc-3.3.x.tar.gz
	cd toolchain/gcc-3.3.x
	( echo 2 ; echo 9 ; echo y ) | make ARCH=arm
	ln -s /usr/src/j820/uclibc/toolchain/gcc-3.3.x/toolchain_arm/bin/arm* /usr/local/bin

Note that the "echo" commands are to select arm, SA-1100 and MMU
in the configuration menu.

Note that there is a bootable image that includes a native arm uclibc toolchain
available as an ext2 image that you can mount -o loop or dd and resize2fs at
	http://www.kernel.org/pub/linux/libs/uclibc/root_fs_arm.bz2
The docs say the image is gcc 3.3.2, but I suppose you can build your own
with the buildroot scripts there...

Finally, remember to make clean or otherwise remove any object file
from different toolchains before you recompile your programs.
