Error in gtkada-3.4.2-gpl that comes with gnat gpl 2013

Error in gtkada-3.4.2-gpl that comes with gnat gpl 2013

[Charly]

Hi,

I just tried to compile the new gtkada-3.4.2-gpl that comes with gnat gpl 2013,
as I do every year after installing the new gnat gpl version, by doing:
./configure --prefix=/usr/local/gnat
make

But this time, I got some error messages in testgtk:

gcc -c -gnatQ -gnatwa -gnatay3abcefhiklmnprt -g -O1 -gnat05 -I- -gnatA /mnt/data5/gmd/sw/gnat-2013/gtkada/gtkada-3.4.2-gpl-src/testgtk/opengl/view_gl.adb

gnatmake: "/mnt/data5/gmd/sw/gnat-2013/gtkada/gtkada-3.4.2-gpl-src/testgtk/opengl/view_gl.adb" compilation error

I assume the problem was caused by the change from gtk-2.x to gtk-3.x.

Any ideas?

GTK 3.x is hugely incompatible to 2.x. Cannot tell anything about testgtk,
but any GtkAda 2.x program must be reviewed and partially rewritten.

For a starting point consider this:

In GtkAda 2013, OpenGL is no longer supported. When you try to compile testgtk,
the test of OpenGl fails.
If you do not use OpenGL, this is not an issue. (just change some config variable about OpenGL like OpenGL=NO)
If you need OpenGL, then you must stick with GtkAda 2012 or build an interface to GtkGLext or ask Adacore.
