(Redirected from Building a cross toolchain)
Install the latest version (sys-devel/crossdev-99999999) of crossdev:
echo 'sys-devel/crossdev **' >> /etc/portage/package.keywords emerge crossdev
Setup some overlays for crossdev to write to and add PuffTheMagic's special overlay of custom ebuilds:
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
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[1]. Reference[2]
If you are using the GNU make 3.82, you should temporarily downgrade it with this command:
emerge -av =sys-devel/make-3.81
If you are already using GNU make 3.81, just continuous:
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
Once the toolchain is built run the following command:
emerge-wrapper --initThis will setup '/usr/arm-none-linux-gnueabi' as your staging directory.
Mask some packages so that you compile against the proper versions:
echo '>=sys-libs/zlib-1.2.4' >> /usr/arm-none-linux-gnueabi/etc/portage/package.mask
