3. Install all needed dependencies and other things necessary for using JHBuild to build GNOME⌗

3.1 Clone inttf modulesets [normal user]⌗

You can of course build original modulesets too, but this will fail and you have to figure out howto fix all errors. I use here currently GNOME 40.3 packages from /pub/GNOME/teams/releng/40.3/ and I have fixed and patched all packages to build and compile now:

cd ~/jhbuild/modulesets

git clone https://[email protected]/inttf/inttf-jhbuild-gnome.git

3.2 Prepare jhbuildrc [normal user]⌗

Copy sample.jhbuildrc

cp ~/jhbuild/examples/sample.jhbuildrc ~/.config/jhbuildrc

Edit ~/.config/jhbuildrc add at least something like:

moduleset = 'inttf-jhbuild-gnome/inttf-gnome-40.3.modules'
modules = ['meta-inttf-gnome']
use_local_modulesets = True

## If you want limit CPU cores add (-j5 means 5 cores are used, default is all cores+1) ##
makeargs = '-j5'
ninjaargs = '-j5'
cmakeargs = '-j5'

3.3 Update apt-file database [root]⌗

JHBuild uses apt-file to find dependencies

apt-file update

3.4 Install needed dependencies to pass JHBuild sysdeps check [root]⌗

This might look ridiculous long list, but actually even this is not enough, this is just a beginning…
