Documentation is not clear.

Right, the documentation could be better. If you have specific GtkAda questions I recommend posting them on comp.lang.ada, there are at least two GtkAda experts I know of who read the posts published here.

Thanks for the answer. The speficic question I have is :
A hello_world_in_ada_gtk3.adb file and
gcc            someoptions
gnatbuild      someoptions
gnatlink       someoptions

It is not the recommended way. Yes, there exists the gtkada-config 
program which generates switches for the compiler and linker. GtkAda 
comes with it. Use gtkada-config this way:

    gcc -c hello_gtk.adb `gtkada-config --cflags`

and gtkada-config --libs is for the linker.

Yet a better way is to use a project file:

with "gtkada.gpr"
project Hello_GTK is
    for Main use ("hello_gtk.adb");
end Hello_GTK;

Then simply run gprbuild -Phello_gtk.gpr. Or open the project in GPS.

Thank you. I have have a working hello_gtk.
Setting up an environment is not always easy. Here is how I did :
#!/usr/local/bin/zsh
export ADA_PROJECT_PATH=/usr/local/:/usr/local/lib:.:
export PATH=/usr/local/gcc6-aux/bin/:$PATH
rm *.o *.ali ../gtkada ../../include
ln -s /usr/local/include ../..
ln -s /usr/local/lib/gtkada ..
gprbuild -Phello_gtk.gpr

Thank you for sharing how you set up your environment.
I haven't done any GTKAda, but I might have to here in the near-/mid-future.

Have a look at the gtkada examples at

Let me know if something is unclear. Your feedback is highly welcome.
