Build
-----
The build system is CMake.
The following libraries are required to be installed:
* zlib, libPNG, libJPEG
* OpenGL
* or on mobile: OpenGL ES (can be optionally enabled on desktop too)
* on Unix: X11
Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY` , ...) the following options are available:

* `BUILD_SHARED_LIBS` (default: `ON` ) - Build IrrlichtMt as a shared library

e.g. on a Linux system you might want to build for local use like this:
git clone https://github.com/minetest/irrlicht
2021-03-18 12:57:17 +01:00
cd irrlicht
2021-03-07 13:24:11 +01:00
cmake . -DBUILD_SHARED_LIBS=OFF
make -j$(nproc)
Platforms
---------
We aim to support these platforms:
* Windows via MinGW
* Linux (GL or GLES)
* macOS
* Android
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.
License
-------
The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.
