Each C compiler requires a special set up or command line to compile the demos. Here are the details on the most popular compilers: SAS/C Each directory has a SCOPTIONS file that contains the necessary parameters. To compile a demo, just go to its directory and run: 1> SC [file.c] Dice C This is like SAS/C, only the command line is a bit longer: 1> dcc -l0 -mD dpk.o [file.c] -o [executable] Storm C There is a StormC project in the Blitter/ source directory. You can use it to compile the PixelList demo, and the template can be applied to the other demos. VBCC In order to get this compiler to work, it requires conversion of the .fd files to its inline file format. Or alternatively the fd2lib program can be used to create a special gms.lib file. I have not tried to do either yet, I am too busy to do this. If anyone out there does the necessary work, please send me the resulting files so that I can include them in future releases.
