+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
