$PROCESSOR_ARCHITECTURE seems to contain the architecture of the host,
but we need the architecture the current MinGW shell is targeting.
$MINGW_CHOST seems to be just that, and on my system it's either
i686-w64-mingw32 (mingw32.exe) or x86_64-w64-mingw32 (mingw64.exe)
(No idea what it looks like for Windows on ARM...)
As fixing this would otherwise break existing savegames, I bumped the
SAVEGAMEVER to "YQ2-4" and added a quirk for older savegameversions:
On Windows i386 savegames that contain "AMD64" instead of "i386" as
architecture are also accepted.
(For YQ2-1 this didn't seem necessary, apparently "i386" was hardcoded)
* No need for global CXXFLAGS. The only difference to CFLAGS is the
standard selector, use $(subst) to derive them from CFLAGS.
* libstd++ must never be manually linked. Doing so only works for the
GNU C++ stack, not for the LLVM stack and anything else. Link with
the C++ frontend instead.
* Force MingW to g++ as CXX.Force MingW to g++ as CXX.
* No need to specify -lm, libm is already part of the global LDFLAGS.
* Windows doesn't need -fPIC.
* The Vulkan renderer doesn't use glad.
This is an enhancement to the previous `yield` work:
* Don't enforce `-march=armv8-a` for aarch64 builds, because it is the
initial ARMv8 revision and compilers will either use that or something
newer.
* Refine preprocessor guards around `asm("yield");` so the code isn't
compiled in if unsupported by the current `-march='.
Submitted by @smcv in #535.
This was requested several times, the last time in pull request #523.
Only the optimization level, warning level and debug stuff may be
overridden. All other options are enforces because they're required.
While here add a new variable to force a debug build: `make DEBUG=1`.
Loading libcurl at runtime instead of linking it at compile time makes
things a lot easier and more reliable on Windows. On other platform
libcurl can be installed as optional dependency instead as an hard one.
This is a very first cut:
* It compiles
* It doesn't crash
What's missing:
* cmake integration
* CURL should be loaded dynamically
* Integration between download code and filesystem
* Likely UTF-8 stuff
* cl_http.c needs cleanup
* Windows support
I've chosen the minimal invasive way for this:
* Import miniz and remove -lz linker flags.
* Create a short header minizconf.h roviding everything we need
originally defined by zconf.h and not provided by miniz.
* Replace zlib.h with miniz.h and minizconf.h.
