GPS and GTK

GPS and GTK

[TI Launchpad]

I have installed both the GNAT Programming Studio (GPS) and GtkAda.
They both seem to work fine, but when I try to build the Simple Window
project under New Project from Template, I get a bunch of errors
saying "file gtk.ads not found." This seems to be a directory/
dependency sort of problem - GPS doesn't know where to look for
GtkAda. I'm running Windows 7, and have GPS installed at C:\GNAT\2011,
and GtkAda installed at C:\GtkAda. I tried adding GtkAda to my PATH;
at the moment my PATH user variable includes C:\GNAT\2011\bin, and my
Path System variable includes C:\GtkAda\bin. Any advice on resolving
this problem is greatly appreciated!

Even though the GtkAda installer likes to install GtkAda rooted at
C:\GtkAda by default, I've always had better success changing the root
GtkAda install path to C:\GNAT\2011 (or whatever year of GNAT you're
using). It seems to help GNAT find all the stuff the GtkAda projects
are dependent upon.

GPS (GPRbuild) looks for installed projects in

   <gnat-root-directory>/lib/gnat/

gtkada.gpr should be located there.

Additionally to that there are GPR_PROJECT_PATH and ADA_PROJECT_PATH
environment variables.

I can't find gtkada.gpr. I've uninstalled GtkAda and reinstalled it
under the GNAT folder, so my directory structure looks like this: "C:
\GNAT\2011\GtkAda". I'm not sure what I need to do to get GtkAda to
work - do you guys have any further suggestions? I really appreciate
your help so far!

It must be under <gtkada-install-directory>\lib\gnat

Then it should be in "C:\GNAT\2011\GtkAda\lib\gnat"

As I wrote, there are many ways. In your case you could make sure that the
directory containing gtkada.gpr is in ADA_PROJECT_PATH, i.e.
ADA_PROJECT_PATH is like: "...;C:\GNAT\2011\GtkAda\lib\gnat;...".

Also PATH should contain "C:\GNAT\2011\GtkAda\bin". Beware that GIMP and
GPS also come with Gtk binaries, you have to choose the order in which they
are loaded. I am usually using GIMP binaries first, because they have more
recent versions. But that could be incompatible of course.

I wouldn't know about that.

My first thought (and the way I meant to recommend) was to install
GtkAda *in the same place as* the compiler, not one level down from it.

I've just tried this, and the installation dialog asks 2 questions: what
compiler (default C:\GNAT\2011) and where to put GtkAda (default
C:\GtkAda).

I edited this so that "where to put GtkAda" read the same as the
compiler location, ie C:\GNAT\2011, and installed.

Now when I go to the demos, for example 
c:\GNAT\2011\share\examples\gtkada\calendar_combo,
I type just "gnatmake -Pdefault" and the demo builds as expected.

Simon's advice is perfect. It's a pain to set ADA_LIBRARY_PATH and
PATH on every machine you'll ever deal with forever or else add the
copious path information needed in build commands.

In my installation, gtkada.gpr is in lib/gnat .

Dear everyone,

Thanks so much for your help! I have gotten it to work; you guys were
exactly right, I just needed to install GtkAda in C:\GNAT\2011. By
doing that, all the GtkAda files got put where they needed to be
relative to the original GNAT files. Anyways, I really appreciate all
your help!
