Divilis: /* Troubleshooting */

Install the latest version (sys-devel/crossdev-99999999) of crossdev:
<source lang="bash">
echo 'sys-devel/crossdev **' >> /etc/portage/package.keywords
emerge crossdev
</source>

Setup some overlays for crossdev to write to and add PuffTheMagic's special overlay of custom ebuilds:
<source lang="bash">
mkdir /usr/local/portage
git clone git://git.webos-internals.org/puffthemagic/portage-overlay.git /usr/local/puff
echo 'PORTDIR_OVERLAY="/usr/local/portage /usr/local/puff ${PORTDIR_OVERLAY}"' >> /etc/make.conf
</source>

Building your toolchain (works for apps and kernels):

It's reported that you should '''NOT''' use ''GNU make'' newer than '''version 3.81''' to compile the toolchain by User:Divilis[http://www.webos-internals.org/wiki/User:Divilis]. Reference[http://old.nabble.com/%22mixed-implicit-and-normal-rules%22-td29471694.html]

If you are using the GNU make 3.82, you should temporarily downgrade it with this command:
<source lang="bash">
emerge -av =sys-devel/make-3.81
</source>

If you are already using GNU make 3.81, just continuous:
<source lang="bash">
crossdev -t arm-none-linux-gnueabi --libc 2.6.1 --gcc 4.3.3-r2 --binutils 2.19.1-r1 --kernel 2.6.23-r3
</source>

Once the toolchain is built run the following command:
<source lang="bash">
emerge-wrapper --init
</source>
This will setup '/usr/arm-none-linux-gnueabi' as your staging directory.

Mask some packages so that you compile against the proper versions:
<source lang="bash">
echo '>=sys-libs/zlib-1.2.4' >> /usr/arm-none-linux-gnueabi/etc/portage/package.mask
</source>
