Cross-compiling Firefox for armhf with clang (trusty)

The main README.md describes how to cross-compile from an amd64 Debian Stretch container. Read that first, then for specifics on building for Ubuntu 14.04 Trusty see these add-on notes. A Trusty binary is the most portable (run it on Xenial or even Stretch).

Instead of adding Bionic sources, make sure your existing sources.list contains the expected Trusty ports.

deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty main restricted
deb-src [arch=armhf]  http://ports.ubuntu.com/ubuntu-ports/ trusty main restricted
deb [arch=armhf]  http://ports.ubuntu.com/ubuntu-ports/ trusty-updates main restricted
deb-src [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty-updates main restricted
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty universe
deb-src [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty-updates universe
deb-src [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty-updates universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty multiverse
deb-src [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty multiverse
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty-updates multiverse
deb-src [arch=armhf] http://ports.ubuntu.com/ubuntu-ports/ trusty-updates multiverse

Then sudo apt update and install the many packages listed in README in addition to rustup and node version 11.

Python 3.4 is the default on Trusty, but Firefox's build process requires 3.5 or newer.

sudo apt install python3.5

We can use the same big patchfile used for Stretch:

patch -p1 < path/to/firefox-armhf/armhf.patch

For clang to use old gcc headers, you must apply a system-level libstdc++ patch:

(cd / && sudo patch -p1 < path/to/firefox-armhf/gcc-4.8-trusty.patch)

Get Firefox source:

apt-get source firefox:armhf
cd firefox-*

Build:

PKG_CONFIG_PATH=/usr/lib/arm-linux-gnueabihf/pkgconfig \
  CONFIG_SITE=/etc/dpkg-cross/cross-config.amd64 \
  DEB_BUILD_OPTIONS=nocheck \
  dpkg-buildpackage -aarmhf -b -d

After configuration errors, replace mozconfig with mozconfig.trusty and edit paths. It's similar to the included mozconfig except s/6.3.0/4.8.4/

PKG_CONFIG_PATH=/usr/lib/arm-linux-gnueabihf/pkgconfig \
  CONFIG_SITE=/etc/dpkg-cross/cross-config.amd64 \
  DEB_BUILD_OPTIONS=nocheck \
  dpkg-buildpackage -aarmhf -b -d -nc

This will likely encounter the shlibsign error so work around that just as described in README.md.

The final build step might complain about missing files from debian/tmp, which is frustrating as the build process nukes the tmp subfolder. To get past that, try pausing with Ctrl+Z followed by:

mkdir -p debian/tmp/usr/lib
cp -rpf obj-arm-linux-gnueabihf/dist/* debian/tmp/usr/lib

Then bring the incremental build back into the foreground with:

fg
