Build Requirements: cmoc (CMOC C compiler- http://gvlsywt.cluster051.hosting.ovh.net/dev/cmoc.html), the cardgame helper sources are in the cardgame/ subfolder. Optional: xroar for emulation.

From the project root (/home/tazrog/cmoc/blackjack):

make all
# or build manually:
cmoc -c --coco -Wfor-condition-sizes -Werror -DNDEBUG -o blackjack.o blackjack.c
cmoc -o blackjack.bin --coco blackjack.o -Lcardgame -lcardgame

Run (emulator):

xroar -ui sdl -run blackjack.bin

Notes

• The cardgame/ folder contains the drawing/audio helpers and a prebuilt libcardgame.a used by the Makefile.
• If you modify files under cardgame/, run make inside that directory to rebuild the library, or update the top-level Makefile as needed.
