Distcc FTW!

To speed-up on Pine A64/Rock64 compilation you can use external machine, which is usually much more powerful (PC with Debian/Ubuntu).

1. On your server

Install distcc and cross-compiler:

apt-get install distcc gcc-aarch64-linux-gnu g++-aarch64-linux-gnu gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf

2. Configure distcc server

Edit /etc/default/distcc:

STARTDISTCC="true"

# Type network address in which your Rock/Pine is running
ALLOWEDNETS="127.0.0.1 192.168.88.0/24"
LISTENER="0.0.0.0"

# Define maximum number of jobs
JOBS="4"

3. Start distcc

systemctl enable distcc
systemctl start distcc

4. On your Pine A64/Rock 64

Install distcc and ccache:

apt-get install -y distcc ccache

5. Configure your Pine A64/Rock 64 environment

When compiling for arm64 edit /etc/environment:

DISTCC_HOSTS=192.168.70.124/4 #
CCACHE_PREFIX=distcc
CC="ccache aarch64-linux-gnu-gcc"
CXX="ccache aarch64-linux-gnu-g++"

When compiling for armhf edit /etc/environment:

DISTCC_HOSTS=192.168.70.124/4
CCACHE_PREFIX=distcc
CC="ccache arm-linux-gnueabi-gcc"
CXX="ccache arm-linux-gnueabi-g++"

Change 192.168.70.124/4 to point to your distcc server. The /4 defines maximum jobs to be executed by your Pine A64/Rock 64, in this case it is /4.

6. Finally

Logout, and login again.

For all new compilations you should be using ccache on your device, and use external (over network) compilation machine with distcc.
