You must have GTK+ 2.0 (version 2.24 or above) and GLib 2.0 (version 2.22
or above) development headers installed to build.
If you have these installed already you may need to install pkg-config so
that they can be located.
Is this a kernel header?
How can I see if I have these installed these headers and how can I install them?
Thank you, that sorted it out.
To understand what just happend is there somehting I can read up on?
I’m curios about what just happend.
Also, why pkgconf and not pkg-config as in the error message.
I only found pkg-config-git and that was in AUR.
