|

required during compilation. Also, you must have the DXE2 package (available
|
||||
on SimTel.Net, courtesy of Andrew Zabolotny) installed in order to build the
|
||||
dynamic modules; if you encounter errors, you can fetch a patched version from
|
||||
my web page.
|
||||
The demos are not built automagically (see Pitfalls below). To make them, use
|
||||
one of the following rules:
|
||||
Static:
|
||||
gcc -o OUT.exe IN.c -lglut -lglu -lgl
|
||||
Dynamic:
|
||||
gcc -o OUT.exe -include dmesadxe.h IN.c -ligl -liglu -liglut -ldl
|
||||
Usage of the dynamic modules requires three things:
|
||||
- include DMESADXE.H in one of the sources, so references inside
|
||||
dynamic modules will get resolved (or use `-include' directive)
|
||||
- link against import libraries (libIgl*.a) and LIBDL.A, which will do
|
||||
the dynamic linkage job for you
|
||||
- put the DXEs somewhere along the library path (LD_LIBRARY_PATH) or
|
||||
in the current directory
|
||||
|
||||
Tested on:
|
||||
CPU: Intel Pentium w/ MMX @166 MHz
|
||||
Mainboard: ViA Apollo VP2 w/ 128 MB SDRAM
|
||||
Video card: Matrox Millenium 2064W w/ 2048 kB WRAM, BIOS v3.0
|
||||
DJGPP: djdev 2.03
|
||||
gcc v3.0.3
|
||||
make v3.79
|
||||
DJGPP: djdev 2.03 + gcc v3.0.3 + make v3.79

for keys, I borrowed the translation tables (and maybe more) from Allegro.

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 call the

destructors (let's hope), thus cleaning up your/my mess ;-)

destructors (let's hope), 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 positioning, drawing, etc),
|
||||
but is enough to make almost all the demos work.

As an addition, stdout and stderr are redirected and dumped upon exit. This
|

means that printf can be safely called during graphics, but all messages come
|

in bulk! A bit of a hack, I know, but I think it's better than to miss them

at all.

at all. "Borrowed" from RHIDE (Robert Hoehne) or SETEDIT (Salvador Eduardo
