When I used Fedora, if I type pkg-config gtkmm-2.0, I will get many results. Of course I have to install gtkmm first. Now, in Slackware after installing gtkmm by source, pkg-config gtkmm-2.0 command give nothing. That means I can not learn gtkmm programming in Slackware.
So what's wrong??? I try pkg-config gtk, pkg-config atk, pkg-config gtk+. They all give me nothing.
