It is not supported in Emscripten's `latest-upstream` LLVM backend,
and doesn't seem necessary in the `latest` backend either.
It was initially added in #22857 to solve a compilation error with the latter.
Part of #30270.
Emscripten is apparently changing the variables in its config file,
causing potential breakage of our build system.
Binaries of the latest/latest-upstream releases are located in a
subfolder of BINARYEN_ROOT called emscripten.
Binaries of the other releases (e.g. sdk-1.38.31-64bit) are instead
placed under the EMSCRIPTEN_ROOT folder.
This PR checks if BINARYEN_ROOT has a subfolder called emscripten, if
that does not exists, it falls back to checking the EMSCRIPTEN_ROOT.
This way we give precedence to the new releases, given that activating
multiple releases sequentially might result in having mismatching
BINARYEN_ROOT and EMSCRIPTEN_ROOT.
Recent Emscripten SDK versions seem to only include the
`BINARYEN_ROOT` variable in the Emscripten configuration file,
whereas the platform's `detect.py` only looked at `EMSCRIPTEN_ROOT`.
Those were disable to keep size small, and on Android avoid the dependency on the STL,
but for tools build (editor) this is not really a concern.
Note: as of today it's not possible to build tools=yes for those platforms, but this
change is one of the necessary steps to enable it.
Fixes#25262.
Include paths are processed from left to right, so we use Prepend to
ensure that paths to bundled thirdparty files will have precedence over
system paths (e.g. `/usr/include` should have lowest priority).
Rename engine.start() to startGame(), new start() takes string arguments
handed directly to main(). Rename Engine.loadEngine() to load().
Add setLocale(), setResizeCanvasOnStart(), setExecutableName() and
preloadFile().
- Implement promise-based JS interface for custom HTML page
integration
- Add download progress callback
- Add progress bar and indeterminate spinner to default HTML page
- Try downloading files multiple times when failing
- Get rid of godotfs.js
- Separate steps for engine initialization, game initialization and game
start
- Allow multiple games on one HTML page
- Substitution placeholders only used in .html file
- Placeholders renamed: $GODOT_BASE => $GODOT_BASENAME,
$GODOT_TMEM -> $GODOT_TOTAL_MEMORY
- Emscripten Module is now Engine.RuntimeEnvironment (no longer a global)
- The Windows, UWP, Android (on Windows) and Linux builds are
tested with Scons 3.0 alpha using Python 3.
- OSX and iOS should hopefully work but are not tested since
I don't have a Mac.
- Builds using SCons 2.5 and Python 2 should not be impacted.
Tried to organize the configure(env) calls in sections, using the same order
for all platforms whenever possible.
Apart from cosmetic changes, the following issues were fixed:
- Android: cleanup linkage, remove GLESv1_CM and GLESv2
- iPhone: Remove obsolete "ios_gles22_override" option
- OSX:
* Fix bits detection (default to 64) and remove obsolete "force_64_bits" option
(closes#9449)
* Make "fat" bits argument explicit
- Server: sync with X11
- Windows: clean up old DirectX 9 stuff
- X11:
* Do not require system OpenSSL for building (closes#9443)
* Fix typo'ed use_leak_sanitizer option
* Fix .llvm suffix overriding custom extra_suffix
All the warnings are factored out of the platform-specific files and moved to
SConstruct. Will have to check that it does not introduce regressions on some
platforms/compilers.
(cherry picked from commit 31107daa1a)
Emscripten injects its loader script when linking, so force relinking
whenever the HTML shell changes.
Also remove useless FULL_ES2 flag, which should be a linker flag, but
would impact performance too much.
