To compile DGD on a Mac, you'll need Symantec C 7.0.4 or newer. De-binhex dgd.proj.hqx and dgd.rsrc.hqx. Move the project file up two folders (into the src folder), and double-click it to start the Project Manager. If you have any trouble with the compiler selecting the wrong source files, remove all the non-Mac folders from the src:host folder. If you want to compile DGD with CodeWarrior, you'll have to make your own project file. Make sure that the size of an integer is 4 bytes, and that the symbol MACOS is #defined. Also, compile for 68000 rather than PowerPC, and turn off the "high level event aware" size flag.
