Issue when trying to build custom deb packages using latest release branch

[ssahu2021]

HI,
I'm trying to generate the custom deb packages for bionic(ubuntu 18.04.5) (with custom option)using tag/v2.0.194 branch, make build-deb target is not generating, using the following steps:

Dependent packages installed
sudo apt-get install -y libcmocka-dev shunit2 expect valgrind uncrustify doxygen graphviz cmake libpcre2-dev

git clone https://github.com/CESNET/libyang.git
cd libyang
git checkout v2.0.194
mkdir build; cd build
cmake ..
make build-deb

But this is not working and I'm getting an error :
make build-deb
make: *** No rule to make target 'build-deb'

Build instructions for Debian are here, and I don't see make build-deb listed there. What instructions are you following?

[ssahu2021]

@jktjkt Do you mean the below steps, which works only with debian/master branch, But we want to compile and generate the latest release branch V2.0.194, Please suggest

Building straight off git

---

Just the normal:

git clone https://github.com/CESNET/libyang -b debian/master
cd libyang
dpkg-buildpackage

Building a Debian .dsc

Again, pretty much the normal:

git clone https://github.com/CESNET/libyang -b debian/master
wget -Olibyang_0.16.105.orig.tar.gz https://github.com/CESNET/libyang/archive/v0.16-r3.tar.gz
cd libyang
dpkg-source -b .

It looks like @oerdnj did some work on this, see the lybiang2-debian-packaging branch. I have no idea how fresh that one is, or what amount of packaging scripts the maintainers want to keep updated in the repo.

But I'm still wondering where did that make build-deb come from?

[ssahu2021]

@oerdnj Can you please help here to generate the custom debian packages for S390x machine using the latest Release tag (v2.0.194)

[ssahu2021]

@jktjkt I have got it from #1278 those compilation steps

[ssahu2021]

@jktjkt @oerdnj As suggested , able to generate the debian packages using lybiang2-debian-packaging branch. have below queries

1. How to generate for latest release tag i,e v2.0.194
2. Some error with secret key

dpkg-buildpackage: info: binary and diff upload (original source NOT included)
 signfile libyang2_2.0.112-6.dsc
gpg: keybox '/root/.gnupg/pubring.kbx' created

dpkg-buildpackage: error: failed to sign .dsc file

[jktjkt]

Looks like you forgot to update the changelog; in that case I think that the Debian's packaging infra is trying to get a "signature from [email protected]" because his entry is the last one in the changelog, and that one obviously cannot make. I don't know whether these signatures are mandatory, but anyway, that would be outside of scope of this project.

Debian package scripts are still not final but they are perfectly fine for building your own packages. However, we are now using apkg for creating them, so you first need to download it using pip install apkg, it is just a small multi-platform useful app for building packages. Then, just run apkg build in the libyang repository, the package will automatically be built, just tested master on Ubuntu 22.04.
