Creating MIPS target system in chroot on x86

[legggo]

Hello.

I'd like to create minimal gentoo based system bootable from cf (something uclibc based like tinygentoo - http://gentoo-wiki.com/TinyGentoo ) on my x86 box for a MIPS based device ( http://www.routerboard.com/rb500.html ). Build it in chrooted environment using cross compilation.

I tried to use experimental uclibc stage3 ( stage3-x86-uclibc-2005.0.tar.bz2 ) with linking uclibc/mips ( ln -snf /usr/portage/profiles/uclibc/mips/ /etc/make.profile ) but I did not suceed - after running ' emerge -uDN world ' I get:
.....
>>> Source unpacked.
HOSTCC scripts/basic/fixdep
as: unrecognized option `-Qy'
make[1]: *** [scripts/basic/fixdep] Error 1
make: *** [scripts_basic] Error 2

!!! ERROR: sys-kernel/mips-headers-2.6.11-r1 failed.
......
when emerging sys-kernel/mips-headers-2.6.11-r1


Any hints or ideas, how to make this properly? Which stage to use? Which profile to use?

Thanks

I have not done any cross-compiling, but I am pretty sure you would have to start with a mips stage tarball, not an x86 one.

But how to use it? I tried following: I've created a x86-uclibc chroot - just to have a uclibc environment. And I've created in it /mips, where there I have extracted mipsel stage3.

My make.conf in uclibc gentoo chroot is:
CFLAGS="-Os -pipe"
CHOST="i386-gentoo-linux-uclibc"
CXXFLAGS="-Os -pipe"
FEATURES="ccache"
USE="make-symlinks minimal"

My make conf inside /mips is:
CFLAGS="-Os -pipe"
CHOST="mipsel-gentoo-linux-uclibc"
CXXFLAGS="-Os -pipe"

I entered uclibc chroot, emerged sys-devel/mips32 and tried:
ROOT=/mips emerge baselayout-lite uclibc busybox

But during compilation I've seen: i386-gentoo-linux-uclibc-strip -x -R .note -R .comment strncasecmp.o
, etc.... so 'ROOT' is ignorred - regarding make.conf.

I copied /mips/etc/make.conf to /etc/make.conf -> to have host spec. mipsel-gentoo-linux-uclibc

I tried again ROOT=/mips emerge baselayout-lite uclibc busybox and

checking for mipsel-gentoo-linux-uclibc-gcc... no
checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler cannot create executables


No success


How to use the mips tarball correctly? I'd like to use emerge and tools around to create a / with apps.

Thanks
