Hello guys,
I've been working on a wrapper for OpenGL and GLUT. I almost have it
working (really)!
But I've got a bug I just can't track down. I'll be more that happy to put
your name
in the credits and sing you praises if you can figure it out. :)
What you will need is glut.dll, glu.dll, opengl.dll, and of course my
programs. The
dll's I think can be located at <www.opengl.org>. And if you are interested
I will
send you what I have.
What it does as of now, is it will go as far as to open a window, clear it
and then
bomb. With the error messages:
>EXW caused an invalid page fault in
>module <unknown> at 0000:005a2d1b.

As you might guess this doesn't help much. I think it is a simple problem,
but I
have no idea where it is.
Any help would be extremely appreciated. And thank you Mathew Hounsell and
Daniel Berstein for your help.
Thanks
Paul Martin

Are you sure you are locking all necessary allocated memory
so that it will not be swapped out to disk ? You may be trying to use
something that has been swapped out to disk.

hello
No, I'm allocating it, but if you are refering to using "lock_memory" that
appears to for the DOS32 platform. The only time it seems to be necessary
to allocate memory is when I retrieve the command line parameters. And the
code is as follows.
>atom array_ad, array_len
>sequence free_stuff
>free_stuff = {}
>----------------------------------------------------------------------------
>procedure handle_comm_line()
>atom string
>integer len
>sequence cmd
>cmd = command_line()
>cmd = cmd[2..length(cmd)] -- actually wants the name of the program
>len = length(cmd)
>array_ad = allocate ((len)*4)
>free_stuff= append(free_stuff,array_ad) -- so I free it later
>for i = 1 to len do
> string = allocate_string(cmd[i])
> free_stuff = append(free_stuff,string)
> poke (string,cmd[i])
> poke (array_ad+((i-1)*4), int_to_bytes(string))
>end for
>array_len = allocate(4)
>free_stuff = append(free_stuff,array_len)

Like I've said before this is a very mysterious problem.
One other thing that I forgot to mention that you will need is Euphoria
2.1, since
it uses multiple callbacks.
Thanks

I don't know if it is help, but...
doesn't it have to be opengl32.dll, as Euphoria is a Win32 only app?
Also do you have the .h file conversion that Pete Eberlein did a long time
ago for open gl?I will attach it.
Any work toward this direction is much appreciated and I will help any way I
can...(with my limited resources)...Please send me any code you wish to
share, I will browse, store and modify as I usually do, but any add ons or
progress will be sent your way as well.
Thanks
Monty King
