Try to update to FPC 2.6.0. 2.4.0 is quite old already (around 3 years).

This is exactly what I thought. You are trying to use the GTK1 unit. The 
unit for GTK+ is called "gtk2". Take a look into "packages/gtk" and 
"packages/gtk2" of a Free Pascal source folder to see the differences in 
the units (just look at the *.pas/*.pp files and ignore the *.inc files 
for now).

Also you could try whether you can compile the examples listed in 
"packages/gtk2/examples".
