Re: [gentoo-embedded] cross compiler for powerpc-softfloat-linux-gnu

[maxime louvel]

Hi,

I have tried to start everything over again.
This time I have followed your advice and xmerge packages one by one.

I have been able to xmerge binutils like that.
But baselayout and glibc are still giving me headache...

Here is what I have after installing everything I have been able to :

For baselayout
----------------
xmerge --root /home/newroot2 -pv baselayout

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] sys-apps/findutils-4.3.11 to /home/newroot2/ USE="-nls
(-selinux) -static" 0 kB
[ebuild  N    ] sys-apps/module-init-tools-3.4 to /home/newroot2/
USE="-old-linux" 0 kB
[ebuild   R   ] sys-apps/baselayout-1.12.11.1 to /home/newroot2/
USE="-bootstrap -build -static -unicode" 0 kB

Total: 3 packages (2 new, 1 reinstall), Size of downloads: 0 kB
--------------

And for glibc:
---------------
xmerge --root /home/newroot2 -pv glibc

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] sys-libs/glibc-2.6.1 to /home/newroot2/ USE="-debug -gd
-glibc-omitfp (-hardened) (-multilib) -nls -profile (-selinux) -vanilla" 0
kB

Total: 1 package (1 new), Size of downloads: 0 kB
---------------


I have enclosed to this mail the results of the xmerge --root /home/newroot2
--nodeps for each needed package.
$package_name.build.log and $package_name.environment for each of them.
The build.log files contain only the last 100 lines (because of the size
allowed for email....). If you'd like the whole ask me, I can send it alone
(it is 9.7M)

I need to xmerge baselayout and glibc.

Indeed I have an embedded powerpc, without FPU. But it has 256 MB of RAM and
for development purpose I am using NFS. Actually I would like to build a
real gentoo on it in order to use it as a native environment and avoid all
the cross compilation.

I haven't find any stage3 for powerpc, without FPU and glibc. I have tried
to update a powerpc-softfloat-linux-uclibc but it misses a lot.

Any idea how I could fix my cross compilation problem ?
Or any idea of an another way of doing my installation ?

thx,

Maxime
