GPS on MacOS 10.9 doesn't find GTKAda

GPS on MacOS 10.9 doesn't find GTKAda

[Laurent]

Hi

I am learning Ada. For the moment a GUI is not really needed for my programs but i was curious and tried the Xadalib-2013 which contains GtkAda and some other things precompiled for MacOS.

Put this in my profile file:

PATH=/usr/local/bin:usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:$PATH
#path for gnat ada compiler + gtkada
export PATH=$PATH:/usr/local/xadalib-2013/bin:/usr/local/gnat/bin:$PATH
export GPR_PROJECT_PATH=/usr/local/xadalib-2013/lib/gnat:$GPR_PROJECT_PATH
export XDG_DATA_DIRS=/usr/local/xadalib-2013/share

When I try to compile this:

with gtkada.gpr

procedure Test is
Begin
    Null;
End Test;

Fails with the message that gtkada.ads can't be found.

This code code from open classroom fails with the message that gtk.ads can't be found.

WITH Gtk.Main ;       USE Gtk.Main ; 
WITH Gtk.Window ;     USE Gtk.Window ; 


PROCEDURE Test01 IS
   win : Gtk_window ;
BEGIN
   Init ; 
   Gtk_New(Win) ;
   Win.show_all ; 
   Main ; 
END Test01 ;

Thanks

Laurent

You can use the gtkada-config script to get the required compiler and 
linker arguments:

gnatmake test01 `gtkada-config`

Alternatively, you can 'with "gtkada"` in your .gpr file, as discussed here:

<http://stackoverflow.com/a/7464775/230513>

Both approaches are covered in "Getting started with GtkAda":

<http://docs.adacore.com/gtkada-docs/gtkada_ug/_build/html/getting_started.html#how-to-compile-an-application-with-gtkada>

You cannot "with" a project file from an Ada source file (as you do in test.adb)
You do this from your own project file instead.

Thank you very much. I have read the threads on stack overflow but I never interpreted it
to put the "with gtkada" into the .gpr file.

@John B. Matthews

From docs.adacore: 
>To build your own application, you should then setup a project file (see the GNAT documentation for >more details on project files), which simply contains the statement:

Oops. I think I have read this article put somehow I have ignored this line :(
Is quite clear compared to the stack overflow threads.

Now both tests compile. Don't really need it for the moment but now I now that GPS works as it should.

Thank you very much
