IrrlichtMt version 1.9
The Irrlicht Engine is an open source realtime 3D engine written in C++.
This is a fork by the Minetest developers that was stripped-down and customized specifically for use in Minetest. It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.
The build system is CMake.
The following libraries are required to be installed:
- zlib, libPNG, libJPEG
- or on mobile: OpenGL ES (can be optionally enabled on desktop too)
- on Unix: X11
Aside from standard search options (
ZLIB_LIBRARY, ...) the following options are available:
ON) - Build IrrlichtMt as a shared library
OFF) - Build example applications
e.g. on a Linux system you might want to build for local use like this:
git clone https://github.com/minetest/irrlicht cd irrlicht cmake . -DBUILD_SHARED_LIBS=OFF make -j$(nproc)
This will put an IrrlichtMtTargets.cmake file into the cmake directory in the current build directory, and it can then be imported from another project by pointing
find_package() to the build directory, or by setting the
CMAKE_PREFIX_PATH variable to that same path.
on Windows system:
It is highly recommended to use vcpkg as package manager.
After you successfully built vcpkg you can easily install the required libraries:
vcpkg install zlib libjpeg-turbo libpng opengl-registry --triplet x64-windows
Run the following script in PowerShell:
git clone https://github.com/minetest/irrlicht cd irrlicht cmake -B build -G "Visual Studio 17 2022" -A "Win64" -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake -DBUILD_SHARED_LIBS=OFF cmake --build build --config Release
We aim to support these platforms:
- Windows via MinGW
- Linux (GL or GLES)
This doesn't mean other platforms don't work or won't be supported, if you find something that doesn't work contributions are welcome.
The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.
