Building GtkAda [with OpenGL] on Windows [XP]

Building GtkAda [with OpenGL] on Windows [XP]

[Antoine Heijde, van der]

Hello All,

I tried to compile the GtkAda testgtk application with the OpenGL
example but it looks like that I am missing the OpenGL binding which
should be used: Packages used in the file /testgtk/opengl/view_gl.adb

    * gl_h
    * Gdk.GL
    * glu_h
    * Gtk.GLArea

So I guess I have to build GtkAda from source.

So I got the files by SVN and installed MinGW[5.1.6] and MSYS
[1.0.11].

Also installed the GTK+ files for windows [2.14.7 bundle].

Reading the INSTALL file from GtkAda:
$ (cd src; patch -p0 < ../contrib/gtkada-2.10-win32.diff)
I did this.

  $ CC='gcc-3.2 -mms-bitfields' ./configure --prefix=<install_dir> --
build=i386-pc-mingw32
Can I use gcc instead of gcc-3.2, because the last is not found.

First tried to build as standaard without OpenGL turned on, and used
the gcc command.
Running $ CC='gcc -mms-bitfields' ./configure --prefix=c:/gtkada --
build=i386-pc-mingw32

Then I am getting the following output:
$ CC='gcc -mms-bitfields' ./configure --prefix=c:/gtkada --build=i386-

Problems seems to be:
./configure: line 1401: cygpath: command not found
ls: libgnat*.dll: No such file or directory
ls: libgnat*.dll: No such file or directory
But no idea how to fix this.

What I have after this when I do "make" compiling is ok, only the
linking is failing with a lot of "undefined references".

So something is wrong. Did I miss a step or should I defined some
environmental variables?

Thanks in advance!

PS I first had a problem that the PATH was not set correctly. For the
GTK version check I got an error about msvcr80.dll missing when the
builded application conftest started. But placing the GTK+ bin files
location first [c:\opt\gtk\bin] solved the problem.

PS2 why is the OpenGL binding not included in the GtkAda installation
for Windows?

Best regards,
Antoine

Hi Antoine

I suggest you go to
gap-contact@adacore.com
join up and download the relevant executables.

There are some problems with these but the solutions are at

Hello Rick,

Thanks for your answer!

Well in the meantime I found the problem, the program cygpath is
missing in my environment and that is why my build was failing.
Because of this failure a needed library was not included
[libgnat.dll] (still to test).

Only don't understand why a cygwin program is used in a mingw
environment, but I will investigate this next week. And hopefully also
build the OpenGL support in it.

And I didn't know about your site but I will keep a watch on it ;-)

PS as I am not an academic user I didn't contact the GAP program of
Adacore.

Best regards,
Antoine
