Mesa 5.0.1 DOS/DJGPP Port v1.3
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Description:
~~~~~~~~~~~~
Well, guess what... this is the DOS port of Mesa 5.0.1, for DJGPP fans... Whoa!
The driver has its origins in ddsample.c, written by Brian Paul and found by me
in Mesa 3.4.2.
Legal:
~~~~~~
Mesa copyright applies, provided this package is used within Mesa. For anything
else, see GPL.
Installation:
~~~~~~~~~~~~~
Unzip and type:
make -f Makefile.DJ [OPTIONS...]
Available options:
Environment variables:

Mainboard: ViA Apollo VP2/97 w/ 128 MB SDRAM
Video card: PowerColor EvilKing3 (Voodoo3 3000 PCI) w/ 16 MB SDRAM
DJGPP: djdev 2.04 + gcc v3.2.2 + make v3.79.1
OS: DOS and Win9x
FAQ:
~~~~
1. Compilation
Q) I tried to run `make' and it exits because `gcc' complains it cannot find
some stupid file.
A) You need LFN support.
A) When compiling for Glide (FX=1), pay attention to Glide path.
Q) Libraries built OK, but linker complains about `vsnprintf' every time I
compile some demo.
A) Upgrade to DJGPP 2.04.
A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
A) The following hack should be safe in 90% of the cases, but if anything
goes wrong, don't come back to me crying. Anyway, patch `src/imports.c'
with the following line:
#define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
Q) `make' complains about DXE3 or something, yet it builds the libraries.
A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
DJGPP distro, or download the separate package from my web page. Read the
DXE3 documentation on how to use them. Hint: build your export object
file; then link it with your application. For example:
dxe3res -o dxe3tbl.c gl.dxe glu.dxe glut.dxe
gcc -o dxe3tbl.o -c dxe3tbl.c
gcc -o OUT.exe dxe3tbl.o IN.c -liglut -liglu -ligl -ldl
2. Using Mesa for DJGPP
Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
A) Is that a question? If you have a Voodoo3/Banshee card, you're lucky (the
Glide port is on my web page). If you have a Matrox Millennium I card,
you just MIGHT be lucky... If you haven't, sorry; everything is done in
software. Suggestions?
Q) I tried to set refresh rate w/ DMesa, but without success.
A) Refresh rate control works only for VESA 3.0. If you were compiling for
Glide, see Glide info. If not, sorry!
Q) I made a simple application and it does nothing. It exits right away. Not
even a blank screen.
A) The pure software drivers (VESA/VGA) support only double-buffered modes.
A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
lazy programmer and I found that the easiest way to keep buffer handling
at peak performance ;-).
Q) My demo doesn't display text. I know I used the GLUT font routines!
A) Then you probably use GLUT as a DXE. Well, there is no direct access to
variables due to the way DXE works. Read the documentation. The author of
GLUT took this into account for _WIN32 DLL's only; I don't want to modify
his headers. The only workaround is to link GLUT the old way :-(
Q) The GLUT is incomplete.
A) See below.
libGLUT (the toolkit):
~~~~~~~~~~~~~~~~~~~~~~
Well, this "skeletal" GLUT implementation was taken from AllegGL project and
heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
Paul and probably others (or probably not ;-). GLUT functionality will be
extended only on an "as needed" basis.
GLUT talks to hardware via PC_HW package which was put together from various
pieces I wrote long time ago. It consists from the keyboard, mouse and timer
drivers.
My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
I borrowed the translation tables (and maybe more) from Allegro -- many thanks
to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
NB: since the DJGPP guys ensured signal handlers won't go beyond program's
space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
can, but it is useless), therefore you must live with the 'Exiting due to
signal SIGINT' message...
The mouse driver is far from complete (lack of drawing, etc), but is enough to
make almost all the demos work. Supports the CuteMouse WheelAPI.
The timer is pretty versatile for it supports multiple timers with different
frequencies. While not being the most accurate timer in the known universe, I
think it's OK. Take this example: you have timer A with a very high rate, and
then you have timer B with very low rate compared to A; now, A ticks OK, but
timer B will probably loose precision!
As an addition, stdout and stderr are redirected and dumped upon exit. This
means that `printf' can be safely called during graphics. A bit of a hack, I
know, because all messages come in bulk, but I think it's better than nothing.
"Borrowed" from LIBRHUTI (Robert Hoehne).
Window creating defaults: 300x300x16 at (0,0), 16-bit depth, 16-bit accum,
8-bit stencil. However, the video mode is chosen in such a way that first
window will fit. If you need high resolution with small windows, set initial
position far to the right (or way down); then you can move them back to any
position right before the main loop.
The following environment variables can customize GLUT behaviour:
DMESA_GLUT_REFRESH - set vertical screen refresh rate (VESA3)
DMESA_GLUT_BPP - set default bits per pixel (VGA needs 8)
GLUT_FPS - print frames/second statistics to stderr
History:
~~~~~~~~
