Jhbuild

[mcatanzaro]

jhbuild sysdeps work on any distro, and let us install the things we
need without knowing distribution-specific names for all the packages.

To use:

$ cd chromium/src/ozone/tools/jhbuild
$ jhbuild -f wayland.jhbuildrc sysdeps --install

Caveat: you need to install python-mako manually, since jhbuild doesn't
support installation of python dependencies yet. But it will appear in
the list of missing system dependencies.

This is done using PackageKit on most distros (which is great and usually doesn't require root) but using apt-file on Debian/Ubuntu (which is a bit slow and unfortunately requires it to be installed and run manually; jhbuild will instruct you on how to do so). I tested only on Fedora 22 and am curious if it works for you on Ubuntu; I expect there will be some build error requiring another dependency to be added to the moduleset, but maybe we get lucky and it will work the first time.

Example output:

$ jhbuild -f wayland.jhbuildrc sysdeps --install

I'm planning to remove the WebKitGTK+ install-dependencies script in favor of jhbuild sysdeps as well, incidentally, but that is a much bigger project.

nice @joone PTAL

I tried to run jhbuild with this patches after installed Ubuntu 14.10. The installation and build work fine in Ubuntu 14.10, but it needs to install apt-file, llvm-dev, libexpat1-dev, libpng12-dev, libxcb-shm0-dev, libjpeg-dev and libpam0g-dev

[mcatanzaro]

Do you remember which particular modules required those packages, so I can add them as sysdeps? I will need to try removing those from my system and see if I can figure it out.

apt-file isn't a sysdep of course, since jhbuild will prompt Ubuntu/Debian users to install that.

@mcatanzaro I don't remember exactly.
Here is the order of packages I installed:
llvm-dev(mesa?)
libexpat1-dev(mesa?)
libpng12-dev (Cairo)
libxcb-shm0-dev (weston?)
libjpeg-dev (weston?)
libpam0g-dev(weston?)

[joone]

@kalyankondapally I think we can merge this patch and then add the missing dependencies.

[mcatanzaro]

I'm working on this now. It's not a big job, I was just a bit lazy in getting around to it.

[mcatanzaro]

I forgot to say, I think this is ready now. :)
