[Tracker] Fun with libmediaart

[Ralph Böhme <rb netafp com>]

Hi!

Guess I'm being stupid, but I can't get current master to build with libmediaart which I installed from git.

libmediaart is installed from git master to /usr/local, simple ./configure && make && make install

I adjusted PKG_CONFIG_PATH such htat pkg-config can pick up the .pc file:

$ echo $PKG_CONFIG_PATH
/usr/lib/pkgconfig:/usr/local/lib/pkgconfig

Problem 1: libmediaart versioning
=================================
tracker looks for libmediaart-1.0, while libmediaart installed itself as:

$ ls /usr/local/lib/pkgconfig/
libmediaart-0.2.pc

If I try to fix the version in tracker's configure.ac:

diff --git a/configure.ac b/configure.ac
index 15e5e33..dec3678 100644
--- a/configure.ac
+++ b/configure.ac

I then run into a dependency issue that prevents bootstrapping:

Problem 2: libmediaart depends on tracker-sparql-0.16
=====================================================

$ ./configure
...
checking for LIBTRACKER_COMMON... no
configure: error: Package requirements (glib-2.0        >= 2.38.0

                            libmediaart-0.2 >= 0.1.0) were not met:

Package 'tracker-sparql-0.16', required by 'libmediaart-0.2', not found

I'm building on Fedora 20, tracker is installed, tracker-devel is not. Installing tracker-devel fixes the 
issue, but how is one supposed to build tracker on a system that doesn't provide tracker and tracker-devel 
packages?

Cheers!
