WebOS Internals PDK Gentoo

Preamble

The page at:

http://www.webos-internals.org/wiki/WebOS_Internals_PDK

Is written for (blah...) Ubuntu, there are some changes that need to be made to get this to work on Gentoo.

GCC

(MAYBE NOT! Hold on!)

You need gcc 3.* for the qemu portions to compile. Gentoo defaults to gcc 4.*

 emerge sys-devel/gcc:3.4

Change your default compiler:

# gcc-config -l
[1] i686-pc-linux-gnu-3.4.6 
[2] i686-pc-linux-gnu-3.4.6-hardened
[3] i686-pc-linux-gnu-3.4.6-hardenednopie
[4] i686-pc-linux-gnu-3.4.6-hardenednopiessp
[5] i686-pc-linux-gnu-3.4.6-hardenednossp
[6] i686-pc-linux-gnu-4.4.4 *

# gcc-config i686-pc-linux-gnu-3.4.6

# gcc-config -l
[1] i686-pc-linux-gnu-3.4.6 *
[2] i686-pc-linux-gnu-3.4.6-hardened
[3] i686-pc-linux-gnu-3.4.6-hardenednopie
[4] i686-pc-linux-gnu-3.4.6-hardenednopiessp
[5] i686-pc-linux-gnu-3.4.6-hardenednossp
[6] i686-pc-linux-gnu-4.4.4

Note the change in where the asterisk is. You need to run

source /etc/profile

in any open shell you intend on using gcc-3* in. Don't forget to set the default compiler back to whatever you used to build your whole system!

gcc-config i686-pc-linux-gnu-4.4.4

KERNEL

You need to make sure kvm support is compiled in your kernel.
