Building LibreWolf from source:

First, let's download the latest tarball.

To download the latest from a script, use wget/curl like this:

export version=95.0.2 # example
wget -O librewolf-$(version).source.tar.gz https://gitlab.com/stanzabird/source/-/jobs/artifacts/main/raw/librewolf-$(version).source.tar.gz?job=build-job
curl -L -o librewolf-$(version).source.tar.gz https://gitlab.com/stanzabird/source/-/jobs/artifacts/main/raw/librewolf-$(version).source.tar.gz?job=build-job

Next, we create ourselves a build folder and extract the tarball.

mkdir build
cd build
tar xf ../librewolf-$(version).source.tar.gz

Next step, if you have not done so already, you must create the build environment:

cp librewolf-$(version)/lw-assets/bootstrap.py .
python3 --no-interactive bootstrap.py --application-choice=browser

It takes about an hour for me to complete, but it needs to be done only once. This step might fail and cause problems. Why Mozilla has no separate 'install-buildenv.py' is a bit beyond me. I would have liked to be able to set up the build environment in one step, in a second step checkout the entire mozilla source, or in our case, use our own source.

Now we're ready to actually build LibreWolf:

cd librewolf-$(version)
./mach build

Also takes me an hour. Then, we can run it:

./mach run

Or make a package:

./mach package

Building LibreWolf source tarball:

You don't need the build environment for this. If you don't have write access, just:

git clone https://gitlab.com/stanzabird/source.git
cd source
make all

If you do have write access, we're first gonna check for a newer version of Firefox:

git clone git@gitlab.com:stanzabird/source.git
cd source
make check

If there is a new version, it's a good time to git commit and trigger a CI build job.

git commit -am v$(cat version) && git push

To build the source archive:

make all

If you have a working build environment, you can build librewolf with:

make librewolf

This extracts the source, and then tries to ./mach build && ./mach package.
