Fails to build from source in Launchpad about blanket

[rafaelmardojai]

Probably you need appstream-glib-devel?

[archisman-panigrahi]

That did not work. I used this package. https://packages.ubuntu.com/focal/libappstream-glib-dev

[rafaelmardojai]

appstream-util?

[archisman-panigrahi]

I will try that. In the meanwhile, please have a look at https://mail.gnome.org/archives/vala-list/2017-April/msg00048.html

Yeah, i have been checking that too.

Similar issue: bilelmoussaoui/nautilus-git#25

[archisman-panigrahi]

Failed even after adding appstream-util. I am confused why it successfully builds in my PC, but fails in Launchpad. All the build dependencies I am using right now are

desktop-file-utils, gettext, meson (>= 0.50), pkg-config, libglib2.0-dev, libappstream-glib-dev, appstream-util

[rafaelmardojai]

Do you have a way to check out how other similar apps like Lollypop are packaged?

[archisman-panigrahi]

I made it based on the debian directory structure of Foliate, whose PPA I maintian. I will look into Lollypop.

[archisman-panigrahi]

I am using the same debian structure as Lollypop or Foliate (could not determine if anything is different), and they build correctly in Launchpad.
The same issue is present when I try to build with pbuilder (in my computer) inside a clean chroot environment. Not sure what is different outside the chroot environment.

[archisman-panigrahi]

In Debian, the dependency is appstream (it comes preinstalled with most operating systems, that is why it was so hard to isolate). All credit goes to Colin Watson, who answered this question.

I have checked that the package builds locally in an isolated environment. I will soon send a pull request with information about the debian package. I will also update the dependencies in the readme.

[archisman-panigrahi]

@rafaelmardojai By the way, is python-gobject really required as a dependency? In my computer, Blanket runs without it, and it is not required to build Blanket either.

This page says it is related to Python 2.x bindings. Also, this package will not be available in the next version of Ubuntu.

[rafaelmardojai]

The dependency is PyGObject, in Fedora is packaged as python3-gobject and in Arch as python-gobject. I don't know the package name in Ubuntu.

I will update the README to python3-gobject.

[rafaelmardojai]

But since Python 2 is deprecated, I don't know if it's better to leave it like this.
