This tutorial walks you though making a debian packaging git repo where upstream branch is the upstream git repo.
We will take libvarnam as an example.
We need to make initial debian directory template with debmake (for golang, ruby or node packages, there are tools that will do this directly). We need a release tarball for this.
cd varnam wget https://github.com/varnamproject/libvarnam/archive/v3.2.6.tar.gz mv v3.2.6.tar.gz libvarnam-3.2.6.tar.gz tar -zxvf libvarnam-3.2.6.tar.gz cd libvarnam-3.2.6 debmake cd ..
Now initialize and pull the upstream repo,
mkdir libvarnam cd libvarnam git init git checkout -b upstream git remote add upstream https://github.com/varnamproject/libvarnam.git git pull upstream master --tags
Now copy the debian directory created by debmake to your repo.
git checkout -b debian/sid v3.2.6 cp -r ../libvarnam-3.2.6/debian/ . git add debian/ git commit -m "Add debian directory created by debmake"
Now create debian/gbp.conf to make debian/sid as debian-branch. Also run origtargz automatically after gbp clone.
[DEFAULT] debian-branch=debian/sid [clone] postclone=origtargz
git add debian/gbp.conf git commit debian/gbp.conf -m "Add debian-brach=debian/sid, run origtargz automatically"
Now you can build your package
Fix build errors and make lintian happy.
