Implements https://github.com/godotengine/godot-proposals/issues/3371. New `target` presets ==================== The `tools` option is removed and `target` changes to use three new presets, which match the builds users are familiar with. These targets control the default optimization level and enable editor-specific and debugging code: - `editor`: Replaces `tools=yes target=release_debug`. * Defines: `TOOLS_ENABLED`, `DEBUG_ENABLED`, `-O2`/`/O2` - `template_debug`: Replaces `tools=no target=release_debug`. * Defines: `DEBUG_ENABLED`, `-O2`/`/O2` - `template_release`: Replaces `tools=no target=release`. * Defines: `-O3`/`/O2` New `dev_build` option ====================== The previous `target=debug` is now replaced by a separate `dev_build=yes` option, which can be used in combination with either of the three targets, and changes the following: - `dev_build`: Defines `DEV_ENABLED`, disables optimization (`-O0`/`/0d`), enables generating debug symbols, does not define `NDEBUG` so `assert()` works in thirdparty libraries, adds a `.dev` suffix to the binary name. Note: Unlike previously, `dev_build` defaults to off so that users who compile Godot from source get an optimized and small build by default. Engine contributors should now set `dev_build=yes` in their build scripts or IDE configuration manually. Changed binary names ==================== The name of generated binaries and object files are changed too, to follow this format: `godot.<platform>.<target>[.dev][.double].<arch>[.<extra_suffix>][.<ext>]` For example: - `godot.linuxbsd.editor.dev.arm64` - `godot.windows.template_release.double.x86_64.mono.exe` Be sure to update your links/scripts/IDE config accordingly. More flexible `optimize` and `debug_symbols` options ==================================================== The optimization level and whether to generate debug symbols can be further specified with the `optimize` and `debug_symbols` options. So the default values listed above for the various `target` and `dev_build` combinations are indicative and can be replaced when compiling, e.g.: `scons p=linuxbsd target=template_debug dev_build=yes optimize=debug` will make a "debug" export template with dev-only code enabled, `-Og` optimization level for GCC/Clang, and debug symbols. Perfect for debugging complex crashes at runtime in an exported project. |

How to build and run
- Build Godot with the module enabled:
module_mono_enabled=yes
. - After building Godot, use it to generate the C# glue code:
<godot_binary> --generate-mono-glue ./modules/mono/glue
- Build the C# solutions:
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin
The paths specified in these examples assume the command is being run from the Godot source root.
How to deal with NuGet packages
We distribute the API assemblies, our source generators, and our custom MSBuild project SDK as NuGet packages. This is all transparent to the user, but it can make things complicated during development.
In order to use Godot with a development of those packages, we must create a local NuGet source where MSBuild can find them. This can be done with the .NET CLI:
dotnet nuget add source ~/MyLocalNugetSource --name MyLocalNugetSource
The Godot NuGet packages must be added to that local source. Additionally, we must make sure there are no other versions of the package in the NuGet cache, as MSBuild may pick one of those instead.
In order to simplify this process, the build_assemblies.py
script provides
the following --push-nupkgs-local
option:
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
--push-nupkgs-local ~/MyLocalNugetSource
This option ensures the packages will be added to the specified local NuGet source and that conflicting versions of the package are removed from the NuGet cache. It's recommended to always use this option when building the C# solutions during development to avoid mistakes.
Double Precision Support (REAL_T_IS_DOUBLE)
Follow the above instructions but build Godot with the float=64 argument to scons
When building the NuGet packages, specify --float=64
- for example:
./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
--push-nupkgs-local ~/MyLocalNugetSource --float=64
