dry

I don't know how to execute a command stored as a variable or how to use ifeq inside of a target, so I have a very redundant Makefile at the moment!

Ideally I'd like to have just one target (all) which would run the stored command on Mac and run it twice on Linux, once with -m32 and once with -m64.

all:
    echo PLEASE SELECT OS, e.g. make linux
    exit 1

mac:
     gcc $(SHARED_OPT) $(GENERAL_CFLAGS) $(PLATFORM_CFLAGS) -o $(BUILD_DIR)$(BUILD_NAME) $(SOURCE) $(LIBRARIES)

linux:
    gcc $(SHARED_OPT) $(GENERAL_CFLAGS) $(PLATFORM_CFLAGS) -o $(BUILD_DIR)$(BUILD_NAME64) $(SOURCE) $(LIBRARIES64) -m64
    gcc $(SHARED_OPT) $(GENERAL_CFLAGS) $(PLATFORM_CFLAGS) -o $(BUILD_DIR)$(BUILD_NAME) $(SOURCE) $(LIBRARIES) -m32
