#
# A Makefile that compiles all .c and .s files in "src" and "res"
# subdirectories and places the output in a "obj" subdirectory
#
# If you move this project you can change the directory
# to match your GBDK root directory (ex: GBDK_HOME = "C:/GBDK/"
GBDK_HOME = ${HOME}/SDK/gbdk/

# You can set flags for LCC here
# For example, you can uncomment the line below to turn on debug output
# LCCFLAGS += -debug # Uncomment to enable debug output
# LCCFLAGS += -v # Uncomment for lcc verbose output
LCCFLAGS +=-Wa-l -Wl-m -Wl-j -Wf--debug
# You can set the name of the .gb ROM file here
