Raspberry PI 4 Ubuntu companion coapp instructions

[Demodian Dragon]

After much work, I managed to get the companion coapp built and running on Ubuntu 20.04 LTS on the Raspberry PI 4.  It took a few days of tinkering, but it works like a champ.  Here's my notes:

install dependencies
=======================

sudo apt install yasm npm gulp

need to update lame/config.guess to current using
=======================

wget -O config.guess http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD

edit build-apps.sh
=======================

change line 96 to

                ./configure --prefix=$ARCHSRCDIR/deps --host=$HOST --disable-intrinsics || exit -1

                                                                   ^^^^^^^^^^^^^^^^^^^^^ add

add after line 120

                OPTS="--target=arm64-linux-gcc"

remove --host for x264 and orc and theora

add at line 854

        build_arch linux aarch64 $BUILDDIR/linux/64 $SRCDIR/linux/64 || exit -1

comment out lines 855 to 862 as raspberry pi 4 is 64-bit only


edit gulpfile.js
======================

add line 46

        "arm64": 64,


build source
=====================

follow instructions for building convertor

follow instructions for building VDH Coapp (good grief this took almost 6 hours)

Install VDH Coapp

Works like a champ with Firefox 91.  Thanks for the great product!  This is my contribution for the free license on Linux.
