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

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.
