Using pkg-config with compiled GTK libraries
Getting started
Sometimes it's necessary to write native GTK snippets to reproduce issues that could be bugs in GTK itself. Of course, it's also important to be able to test these snippets across multiple versions of GTK, specifically GTK3. As a prerequisite, please see the article about compiling GTK. After you've compiled your version of GTK and have a .libs directory, proceed to the next step.
Compiling GTK applications using system GTK
GTK compiles its applications using information from pkg-config. pkg-config has rule files that it uses to store information about the program's needs. These files are located in:
/usr/lib64/pkgconfig
Compiling an ordinary GTK application using your system GTK is easy. Follow the steps here and you are done: https://developer.gnome.org/gtk3/stable/gtk-compiling.html But compiling a GTK application using your "custom" compiled GTK libraries requires modification of the pkg-config rule files.
Modifying pkg-config rule files
Navigate to the following directory:
/usr/lib64/pkgconfig
Using sudo/elevated permissions, make a copy of the gdk-3.0.pc and gtk+-3.0.pc files. You'll want to have a backup in case something goes wrong. Next, we are going to edit them.
