CMakeLists.txt already opt-in enables CMAKE_{C,CXX}_COMPILER_LAUNCHER=
ccache when found (b49907de); CI just never installed ccache or persisted
its cache dir across runs. Wires actions/cache + ccache install into both
linux-build and windows-build, keyed on CMakeLists.txt's hash. Game
sources are frozen, so this should give a near-total hit rate after the
first run on each job.
YAML-validated; the actual hit-rate payoff needs a real CI run (cold, then
warm) to confirm -- not verifiable locally.

# Jobs:
|
|
#
|
|
# linux-build — ubuntu, system GCC. Actually compiles + links (unlike
|
|
# validate), then packages the Linux bundle (exe + README +
|
|
# licenses + prepare-assets, NO ROM / assets / bundled libs)
|
|
# via tools_pc/bundle-linux.sh and uploads it. Surfaces
|
|
# GCC-on-Linux strictness gaps MinGW misses. Not a runtime
|
|
# claim; not a required check yet.
|
|
#
|
|
# validate — ubuntu, configure-only. Byte-compiles the tooling,
|
|
# regenerates the US ROM-asset symbol file, and CMake-
|
|
# configures ntsc-final (REGION_DEFS, the source list, and
|
|
# that SDL2 / zlib / OpenGL are discoverable). No ROM is used.
|
|
# Does NOT compile; running on ubuntu is NOT a claim the port
|
|
# works on Linux.
|
|
#
|
|
# windows-build — windows/MSYS2, the real supported platform. Compiles and
|
|
# links the full executable, then packages the distributable
|
|
# bundle (exe + runtime DLLs + README + licenses, NO ROM /
|
|
# assets) via tools_pc/bundle-win.sh and uploads it. Neither
|
|
# the ROM nor extracted assets are needed to BUILD (they are
|
|
# runtime-only), so CI builds but never runs the port.
|
|
#
|
|
# release — tags only (v*). Downloads the Windows + Linux bundles and
|
|
# attaches both to a DRAFT pre-release for that tag. Draft, so
|
|
# a human does the ROM smoke-test on each platform and hits
|
|
# Publish. This is the only job granted contents: write.
|
|
|
|
jobs:
|
|
# Did this change touch anything outside docs / licenses? No workflow-level
|
|
# paths-ignore exists (see the `on:` comments), so this job is the single
|
|
# place a docs-only push OR pull request is filtered out — a PR is diffed
|
|
# against its base sha, a branch push against `github.event.before`. Tag
|
|
# builds always run. Docs globs: **.md, docs/**, LICENSE, NOTICE.
