After clone 2r11-2048 you need to initialize the submodules:
git submodule update --init
If you want to build the version that uses accacia instead of ncurses using Hefesto:
After to follow the steps to get Hefesto installed on your system, being inside the root of 2r11-2048 subdirectory just type:
hefesto
The above comand will build the standard version of 2r11-2048 and the following command will generate a "vintage"
minimalist version of 2r11-2048 that uses libaccacia.
hefesto --cflags=-DUSE_ACCACIA
On both cases the binary will be generated inside the bin subdirectory named as 2048.
Without hefesto try to run the shell script build.sh.
If you want to generate a version that uses libacaccia in replacement of ncurses you should add the following
line inside the 2048.h file (just after the includes section) before run build.sh:
#define USE_ACCACIA 1
