Hello .......from Victor L. Miller
I have used DJGPP and ALLEGRO very successfully with Windows 95 / 98 in the
DOS box .....
Now I am trying to use it under WindowsNT (forced onto it at work) .....
I have just read your WindowsNT section in your DJGPP FAQ's .....
I wanted to give you direct feedback on my experiences......
Everything you have in your FAQ's is right .....
I did not have the selector limitation ...but
I did find that RHIDE needed the -M switch (which can be permanently set
with the
RHIDEOPT= -M in the DJGPP.env file .....(avoids typing the -M every time)
I found that DJGPP works under WindowsNT and can compile with ALLEGRO and
build a full *.exe executable .......
HOWEVER .......
Allegro can NOT invoke any good graphics modes set_gfx_mode( );
I could only get 320 x 200 x 8 bits (256 colors)
Basically , If you want to create an application with any graphics content
(certainly all games / simulations etc) effectively
ALLEGRO doesn't work under Windows NT ......
I mean what good is pixel-ated 320 x 200 stuff ?
In your FAQ's it is mentioned that WindowsNT doesn't allow arbitrary direct
access to the SVGA registers, ......
My question is :
Is this operating system design / behavior expected to be seen in all
subsequent
Microsoft operating systems such as Windows2000 .... ?
The reason I ask is that although WindowsNT is not "mainstream" for the home
user
(mostly just big businesses) if this type of non-support of SVGA gets
included in
the home user type of operating system that will really put a damper on
the game programmers ....using .... DJGPP and ALLEGRO .......
because the SVGA modes won't be accessible .....
Do you guys have any thoughts about this and maybe a plan to address this ?
I would appreciate any responses in relation to this issue ....
Many Thanks,
Victor L. Miller
