GTK+ and PKG_CONFIG_PATH problems!

Hello fellas,


I have gtk+3.0 installed but I'm having a hard time compiling a simple program that merely shows a window. When I type at terminal:

gcc `pkg-config --cflags --libs gtk+-3.0.0` gtk.c -o gtk

I get the error:

Package gtk+-3.0.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0.0' found
gtk.c:1:20: fatal error: gtk/gtk.h: No such file or directory
compilation terminated.

I'm pretty much a newbie on linux, so I tried to set the PKG_CONFIG this way (dunno if maybe I'm missing something to set it correctly):

export PKG_CONFIG_PATH=/Downloads/gtk+-3.0.0

Any help I would appreciate guys...

Did you install the GTK+ package using a package manager?
If yes, I suggest looking for a package call the same name with dev added to it.
This is a guess from a Windows user; so, might be wrong.

Been at least two years since I used Linux and installed GTK+ development files.
