The pinephone is a cheap generic linux phone.

=== Cross compiler ===

First, we will be compiling on a host gentoo system. To do this, first install
crossdev and the needed toolchain (See [[cross_toolchain]])

{{{
emerge -av git ninja crossdev
crossdev --target arm-none-eabi
  }}}
  
=== GPU Support ===

The pinephone pro uses a Mali T860 quadcore CPU, and therefore is run using the
lima drivers. In the phones make.conf, be sure to add

{{{
#/etc/portage/make.conf (chroot in phone)
VIDEO_CARDS="lima"
  }}}
  
In your global use, be sure to add

{{{
#/etc/portage/make.conf (chroot in phone)
USE="gles gles2-only"
  }}}

This ensures that we will only compile programs using OpenGL ES, or OpenGL for
embedded systems.
