How to build the server locally for testing

It is expected that you have an environment where ArduPilot can be built. Otherwise, see https://ardupilot.org/dev/docs/building-setup-linux.html.

Fork and Clone the ArduPilot/CustomBuild repository
In the directory containg the CustomBuild repo just cloned, create a /base subdirectory and change to that directory.
Clone a fork of the ArduPilot/ardupilot repository. The structure should appear similar to that below:

Directory structure

default directory structure is as follows

/home/<username>
-CustomBuild
-base
--ardupilot

Install Flask

python3 -m pip install --user -U flask

Use --basedir to adjust the base directory, the default one is base.

Running

To run, in the CustomBuild directory execute the following command:

./app.py

Once running, you will be given a link to a local host port in which the interface is displayed for the build server. It can be run at this point. Output will NOT be accessible via the interface buttons for build directory. Builds are stored in the base/builds subdirectory

For Apache web server on Ubuntu with WSGI

To create a full server with network access:

Install mod_wsgi for python 3:

sudo apt-get install apache2 libapache2-mod-wsgi-py3 python3 python3-pip

update /etc/apache2/envvars

set correct username and group (default is www-data)
add export PATH=/opt/gcc-arm-none-eabi-10-2020-q4-major/bin:$PATH to end of file (this is default location if you have followed the dev env setup instructions above)

Copy the config file to /etc/apache2/sites-available/ and specify the correct directory.
Edit the file as necessary for your use case
Enable the file:

sudo a2ensite CustomBuild.conf

To restart Apache:

sudo apache2ctl graceful

To stop Apache:

sudo apache2ctl stop

To start Apache:

sudo apache2ctl start
