I can not get the ada Opengl sample package at
http://www.niestu.com/languages/oglada/ to work in GNAT (win98).
For example when try to run the fog.adb ie retruns this message when
building
...
./glut.o: In function 'glut glutcreatewindow$2:
F:/open ada/test/f:/openad~1/test/glut.adb:29:undefined reference to
'glutCreatWindow'
./glut.o: In function 'glut glutinitdisplaystring$2:
f:/open ada/test/f:/openad~1/test/glut.adb:29: undefined reference to
'glutInitDisplayString'
... (and so on for every gl function/procedure it uses)

Now I do have the gl and glut files in the folder f:/open
ada/test/f:/openad~1/test/.

Also how do you use a makefile in GNAT?

For OpenGL/GLUT under NT look at my homepage there is a binding
and some demos.

Re: OpenGL

I found out that some enviromental varibles needed to be set first,

set ada_include_path=G:\adaold\bindings\glut-3.7
set ada_objects_path=G:\adaold\bindings\glut-3.7

which I put in a bat file before loading GNAT

Also I noted that the GLUT.DLL need to be changed to another which suppored
ADA.

Thanks eveybody.

That's obviously wrong in the general case. I would suggest
any further discussion of this be moved to chat@gnat.com since
it is very much GNAT specific.

That is a bad suggestion. In my experience deja.com keeps these messages
for a much longer time than your server seem to keep the chat messages.
This means that we have a decent chance to find an answer by searching
at deja.com long after your server have discarded the messages.

The big advantage of chat@gnat.com is that there are MANY
participants who have given up a long time ago on CLA (in
my experience relatively few serious Ada programmers bother
to read CLA any more, they find the signal-to-noise ratio
too low), so you are far more likely to get useful answers
there, and to avoid incorrect answers.

I think you will find it better in practice to have a smaller
database to search of accurate answers than years of CLA
when it comes to GNAT specific technical questions.
Most of the threads on CLA are pretty useless from the point
of view of providing accurate technical information.

We also make a point of correcting incorrect submissions
on chat@gnat.com, whereas incorrect answers have been known
to go by on CLA without correction!
