-```
-webrtc-native/
-├─bin/
-├─godot-cpp/
-| └─godot_headers/
-├─src/
-└─webrtc/
-```
+### Compiling the extension.

-### Compiling the cpp bindings library
-First, we need to compile our cpp bindings library:
-```
-$ cd godot-cpp
-$ scons platform=<your platform> generate_bindings=yes
-$ cd ..
-```
-
-> Replace `<your platform>` with either `windows`, `linux` or `osx`.
-
-> Include `use_llvm=yes` for using clang++
-
-> Include `target=runtime` to build a runtime build (windows only at the moment)
-
-> Include `target=release` or `target=debug` for release or debug build.
-
-> The resulting library will be created in `godot-cpp/bin/`, take note of its name as it will be different depending on platform.
-
-### Building WebRTC
-
-Use [this script](https://github.com/Faless/webrtc-builds) to build and package the WebRTCLibrary (`branch-heads/68`), or [**download latest pre-compiled binaries**](https://github.com/Faless/webrtc-builds/releases)
-Extract content of `include` into `webrtc/include` and content of `bin` into `webrtc/<your platform>`
-
-### Compiling the plugin.
+To build the GDExtension version of the plugin (Godot 4.0) run the following command from the `webrtc-native` folder:

 ```
-$ scons platform=<your platform> target=<your target>
+$ scons platform=<your platform>
 ```

-The generated library and associated `gdns` will be placed in `bin/webrtc/` or `bin/webrtc_debug/` according to the desired target. You simply need to copy that folder into your project.
+This will build all the required dependencies into a single shared library.
+
+To build the GDNative version of the plugin (Godot 3.x) run the following command instead:
+
+```
+$ scons platform=<your platform> godot_version=3
+```
+
+> Replace `<your platform>` with either `windows`, `linux`, `osx`, `android`, or `ios`.
+
+> Include `target=release` or `target=debug` for release or debug build (default is `debug`).
+
+The resulting library and associated `tres` or `gdextension` will be created in `bin/[extension|gdnative]/webrtc[_debug]` depending on the `target` and `godot_version`.
+
+You simply need to copy that folder to the root folder of your project. Note that you will have to build the library for all the desired export platforms.

Disable OpenSSL caching since it causes issues as it doesn't properly cache generated header files. Add hack to prepend PATH and few other vars (should probably be added to upstream godot-cpp), and clone scons envs when building ssl/rtc (so that PATHs are properly setup).	2022-11-28 03:10:20 +01:00
