I've taken over someone else's project code which uses #defines to select
which region the code is being compiled for. Instead of hard-coding these
#defines, i would like to edit the makefile to specify the region at compile
time.
ie. I would like to be able to enter "make USA" or "make Mexico" and have
that automatically define REG_UNITED STATES or REG_MEXICO when compiling.
I've tried to check the MAKECMDGOALS variable, but I still get a "No rule to
make target "USA". Stop" error.
my makefile currently is:
