I'm having trouble building Ardour. Can anyone help me with dependencies? I have tried reinstalling everything to no avail.

Ubuntu 18.04.4

Solution 1:

Well, it says clearly

Checking for 'glib-2.0' >= 2.28    : yes 
Checking for 'glib-2.0' >= 2.68    : not found 
...
...
Checking for 'glib-2.0' >= 2.68
['/usr/bin/pkg-config', 'glib-2.0 >= 2.68', '--cflags', '--libs', 'glib-2.0']
err: Requested 'glib-2.0 >= 2.68' but version of GLib is 2.56.4

Which is consistent with my Ubuntu 18.04 LTS: It has Glib 2.56.4. The package name is libglib2.0-2.56.4-0ubuntu0.18.04.8, the -dev package which you need for building software is libglib2.0-dev-2.56.4-0ubuntu0.18.04.8.

But it wants the newer Glib 2.68. Ubuntu 18.04 doesn't have that. Since it insists on that newer Glib, your only option is to upgrade your Ubuntu; not sure if using a PPA for libglib2.0 would help, or if it would break other software that you have installed.

But you can simply install "ardour" from standard 18.04 repositories:

apt search ardour

ardour/bionic 1:5.12.0-3 amd64
  the digital audio workstation

ardour-data/bionic,bionic 1:5.12.0-3 all
  digital audio workstation (data)

ardour-video-timeline/bionic,bionic 1:5.12.0-3 all
  digital audio workstation - video timeline
