# Atari ST (m68k-atari-mint-gcc) build rules: JoeyLib's library for the ST,
|
|
# and programRules, the ST's rules for one program, which make/programs.mk
|
|
# instantiates for every program (a project reaches both through
|
|
# make/project.mk). JoeyLib's own examples and gates are at the end.
|
|
#
|
|
# The same rules build the STe variant: make/ste.mk sets ATARI_VARIANT to
|
|
# ste and includes this file. That build lands in build/ste, compiles
|
|
# src/atarist/ste as well, and defines JOEYLIB_ATARI_STE (BLiTTER, DMA
|
|
# sound, 4-bit palette; its jlInit refuses anything but an STe or Mega
|
|
# STe). The ST build never compiles src/atarist/ste.
