Adds support for LTO on macOS and Android. We don't have much experience
with LTO on these platforms so for now we keep it disabled by default
even when `production=yes` is set.
Similarly for iOS where we ship object files for the user to link in
Xcode so LTO makes builds extremely slow to link.
`production=yes` defaults to full LTO.
ThinLTO is much faster for LLVM-based compilers but seems to produce
bigger binaries (at least for the Web platform).
Modules can now call:
env.module_add_dependencies(name: str, deps: list, optional: bool)
To add required or optional dependencies during the "can_build" step.
Required dependencies will be checked and the module will be not be
enabled when they are missing, printing a warning to notify the user.
Adds SCons options to disable Brotli and Graphite.
Adds option categories to the build profiles editor.
Adds options default state to the build profiles editor.
Adds Text Server related options to the build profiles editor.
Fix misplaced OpenGL/Vulkan SCons options.
This PR is a continuation of #50381 (which was implemented exactly a year ago!)
* Add a visual interface to select which classes should not be built into Godot (well, they are built if something else uses them, but if not used the optimizer will remove them out).
* Add a detection system to scan the project and figure out the actual classes used.
* Added the ability for SCons to load build profiles.
Obligatory Screen:
A simple test with a couple of nodes in the scene resulted in a 25% reduction for the final binary size
TODO:
* Script languages need to implement used class detection (left for another PR).
* Options to disable servers or server functionalities (like 2D or 3D physics, navigation, etc). Are missing, that should also greatly aid in reducing binary size.
* Options to disable some modules would be desired.
* More options to disable drivers (OpenGL, Vulkan, etc) would be desired.
In general this PR is a starting point for more contributors to improve and enhance this functionality.
This doesn't change the behavior when `--jobs`/`-j` is specified as a
command-line argument or in `SCONSFLAGS`.
The SCons hack used to know if `num_jobs` was set by the user is derived
from the MongoDB setup.
We use `os.cpu_count()` for portability (available since Python 3.4).
With 4 CPUs or less, we use the max. With more than 4 we use max - 1 to
preserve some bandwidth for the user's other programs.
We shouldn't presume that future compilers will not have false positives or
find new occurrences of this warning, which would break compiling old versions
of the engine without passing custom `CXXFLAGS`.
Follow-up to #60652.
SConstruct change also makes it possible to outright delete the `editor`
folder in a `tools=no` build, which we use in CI to ensure no invalid
cross-dependencies are added.
It has been disabled in `master` since one year (#45852) and our plan
is for Bullet, and possibly other thirdparty physics engines, to be
implemented via GDExtension so that they can be selected by the users
who need them.
This reverts #53828 which had caused a significant drop in incremental
rebuild time for debug builds (from 10s to 23s on my laptop).
The "faster but unsafe" options are re-added, as well as adding
`max_drift=60` which we didn't use previously.
These options speed up SCons' own processing of the codebase to decide
what to build/rebuild (i.e. the first step before actually calling the
compiler). This will therefore not make much difference for scratch
builds, and is mostly useful for incremental rebuilds (including "null"
rebuilds with no change).
These options are enabled automatically for `debug` builds, unless
`fast_unsafe=no` is passed.
They are disabled by default for `release` and `release_debug` builds,
unless `fast_unsafe=yes` is passed.
The Godot Project Leadership Committe has decided to update the sponsoring
tiers so that the Platinum Sponsorship no longer includes a logo on the
editor splash screen.
This lets us reclaim the editor splash screen space for community-related
content instead of sponsors (e.g. a different community-designed splash
screen for each stable branch?).
Also removes two Platinum Sponsors whose sponsorship has expired earlier this
year.
When disabling specific modules, misspellings can occur. Additionally,
when switching between the `3.x` and `master` branches frequently,
it's possible to forget about renamed modules such as `lightmapper_cpu`
versus `lightmapper_rd`.
Note, the editor build requires the mbedtls module to be manually
enabled, as it is currently needed as a ResourceUID dependency.
This will need to be addressed in a separate PR.
- Rename OpenGL to GLES3 in the source code per community feedback.
- The renderer is still exposed as "OpenGL 3" to the user.
- Hide renderer selection dropdown until OpenGL support is more mature.
- The renderer can still be changed in the Project Settings or using
the `--rendering-driver opengl` command line argument.
- Remove commented out exporter code.
- Remove some OpenGL/DisplayServer-related debugging prints.
First implementation with Linux display manager.
- Add single-threaded mode for EditorResourcePreview (needed for OpenGL).

We've had many issues with WebM support and specifically the libvpx library
over the years, mostly due to its poor integration in Godot's buildsystem,
but without anyone really interested in improving this state.
With the new GDExtensions in Godot 4.0, we intend to move video decoding to
first-party extensions, and this would likely be done using something like
libvlc to expose more codecs.
Removing the `webm` module means we can remove libsimplewebm, libvpx and
opus, which we were only used for that purpose. Both libvpx and opus were
fairly complex pieces of the buildsystem, so this is a nice cleanup.
This also removes the compile-time dependency on `yasm`.
Fixes lots of compilation or non-working WebM issues which will be linked
in the PR.
Current SCons 4.2.0 still supports Python 3.5 but deprecated it, and support
will be removed in the next release.
It's also become needlessly restrictive to prevent ourselves from using Python
3.6 f-Strings, so it's time to up the requirement.
They haven't really helped save much time on incremental rebuilds, and they do
cause potential issues with build correctness (and possibly even one of the cause
for overly eager incremental rebuilds).
