[gtkada] Building GtkAda [with OpenGL] on Windows [XP]

[Antoine Heijde, van der]

Hello,

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

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
