# check-blank.sh - Smoke-test the new-port template (src/blank/blank.c).
|
|
#
|
|
# A blank port has no toolchain, so we compile it with the HOST cc just to
|
|
# prove three things stay true as the library evolves:
|
|
# 1. The template + the JOEYLIB_PLATFORM_BLANK blocks in platform.h still
|
|
# compile (catches a new platform-#if dispatch point that forgot a BLANK
|
|
# case -- e.g. assetLoad.c's tile target, the sprite emitter selector).
|
|
# 2. blank.c + the generics LINK with no unresolved jlp* ops -- i.e. a new
|
|
# chunky port really does get everything except the platform services for
|
|
# free from src/generic/.
|
|
# 3. The same sources stay gnu89-clean: no C99-only construct except `//`
|
|
# comments. BeOS R5 builds with gcc 2.95 (x86) and Metrowerks mwcc (PPC),
|
|
# and neither speaks C99. This pass is a lint, so it always uses gcc
|
|
# (-Wc90-c99-compat is gcc-only) whatever CC says.
|
|
#
|
|
# Source set mirrors a real blank-port build: core + ALL of src/generic
|
|
# (including the stub sprite emitter) + blank.c; NOT src/codegen/spriteCompile.c
|
|
# (that's only for ports with a per-CPU JIT emitter).
