I have 12 bugs to be merged but hope to solve it in next week.
If someone wants to bootstrap compiler then I have a new procedure.
1. You need to fetch few branches (select one gcc version):
lp:~hrw/binutils/pkg-ubuntu
lp:~hrw/eglibc/eglibc-2.12-pkg
http://github.com/hrw/debian-pkg-gcc-4.5
http://github.com/hrw/debian-pkg-gcc-4.4
2. Need patches for linux source package:
http://patchwork.ozlabs.org/patch/60732/
http://launchpadlibrarian.net/52688720/0001-linux-add-support-for-building-
selected-stages-of-k.patch
3. Fetch current Ubuntu versions (select gcc-4.4 or gcc-4.5):
apt-get source -o APT::Get::Only-Source=1 linux gcc-4.4 eglibc binutils
4. Apply changes (from branches or patches for linux). This can be more time
consuming.
5. Build "binary-indep" for each component to get -source binary packages.
6. Eglibc requires hack to get unpatched sources in -source package. Apply
attached "eglibc-hack.patch" - should help.
7. Install all -source packages in your system. This will give their debian/
directories which will be re-used during bootstrap.
8. "make all" with attached Makefile
No warranty that it will work for you as I could forget something. If
everything will go fine "build-rootfs" directory will contain cross compiler.
