# build.sh — compile and optionally run a single C64 program with Oscar64.
|
|
#
|
|
# Usage:
|
|
# ./build.sh # compile helloworld.c → build/helloworld.prg
|
|
# ./build.sh -e # compile, then run in the oscar64 built-in emulator
|
|
# ./build.sh -v # compile, then run in x64 (VICE standard)
|
|
# ./build.sh -V # compile, then run in x64sc (VICE cycle-exact)
|
|
# ./build.sh -c # just compile (default; -c is a no-op for clarity)
|
|
#
|
|
# Output (in ./build/):
|
|
# helloworld.prg — loadable C64 program (run with x64, VICE, or real hw)
|
|
# helloworld.asm — full 6502 listing
|
|
# helloworld.map — region/section/object placement
|
|
# helloworld.lbl — VICE monitor label commands
|
|
|
