A player's AppImage build of 0.7.1 stopped in its compile step after eight minutes of RomFS work: four
files did not compile, because the kit builds with the system's compiler and headers and theirs were
older than the runtime needs. vk_pipeline.c and vk_device.c name VK_KHR_pipeline_binary,
VK_KHR_dynamic_rendering_local_read and VK_KHR_shader_maximal_reconvergence, which their Vulkan headers
did not declare, and ui/menu.cpp takes its font in with #embed, which clang has from version 19.
- Vulkan headers: tools/vulkan_pin.py holds the release the other builds use (1.4.363, the archive and
hash tools/make_release_linux.py already pinned, which now reads them from there). The AppImage carries
its C headers in toolchain/vulkan-headers and builds against them whatever the system has; a kit or a
source checkout uses the system's when they are at least that release and fetches the pinned ones
otherwise (build_game.py vulkan_include). Their folder goes first on the include path of the runtime's
sources only, so the lifted code's objects keep their keys, and a runtime object compiled before
against the system's headers is taken over instead of compiled again. AppRun no longer asks for the
system's Vulkan headers.
- #embed: tools/build_shaders.py also writes the font's bytes as runtime/ui/roboto_ttf.h (ignored by git,
carried by a kit), and menu.cpp includes that where the compiler has no __has_embed. With #embed
nothing changes.
- Before its long steps a Linux build that will compile now checks every runtime source that needs no
header of the install with the compile step's own command (clang -fsyntax-only) and links an empty
program against the game's libraries (make_game.py preflight): an old compiler, an old header or a
missing development package stops it in the first seconds with the compiler's own errors. A failed
compile names every file that failed, not only the three whose errors it prints.
Checked on Windows: tests/launcher_test.py passes with four new tests (117); the header of bytes and
#embed give the same 162,588 bytes, and both branches of menu.cpp compile; the early check passes on the
Windows file set with clang 23 and stops on files made to fail; the 34 local headers of release 363 are
the upstream tag's files by git blob id. Not run: anything on Linux, the pinned archive's download, a
compiler older than 23.
