kotlin-native-opengl

Renderer / game engine in Kotlin/Native with use of some native libraries. Currently has only the OpenGL backend. Maybe it will support Vulkan sometime in the future.

Building

Automatically

Running the gradle tasks should be enough.

./gradlew buildNativeProjects generateInterops build

It will automaticaly compile all native projects and the the kotlin one. This script is experimental but tested on MSYS2 for Windows. Building on other platforms is not tested, however in theory should work.

You need to have working environment with: gcc, g++, cmake, bash, java (for Gradle).

This will take around 5 - 10 minutes.

Manually

1. Build all native projects in thirdparty folder using cmake to cmake-build-debug directories.
2. Build the main Kotlin project with gradle by the build task. Get a coffee ☕, this will take some time.
