Linapple is an emulator of Apple2 (Apple][, Apple 2, Apple2e) series computers for Linux or other systems with SDL support, which works out of the box. It derives from AppleWin, and almost as powerful as AppleWin is.
When you run make you might get this: "error: use of undeclared identifier 'usleep'". To fix this, edit the files timer.cpp, frame.cpp, and serialcomms.cpp. Insert #include <unistd.h> at the beginning of each of these files. Run make clean and then run make again. There might be some warnings but aslong as there are no errors, it should work.
Cannot run because it gets compile errors when I try to build it.
