CImageWriterPNG::writeImage() and writeJPEGFile() explicitly allocate and deallocate memory with `new` and `delete`, which is prone to programming errors. The code also has non-functional error handling: When memory allocation fails, `new` throws an `std::bad_alloc` exception and never returns `nullptr`, so the check for `nullptr` is always false.

IrrlichtMt version 1.9
IrrlichtMt is the 3D engine of Minetest. It is based on the Irrlicht Engine but is now developed independently. It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.
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
- SDL2 (see below)
Aside from standard search options (ZLIB_INCLUDE_DIR
, ZLIB_LIBRARY
, ...) the following options are available:
ENABLE_OPENGL
- Enable OpenGL driverENABLE_OPENGL3
(default:OFF
) - Enable OpenGL 3+ driverENABLE_GLES2
- Enable OpenGL ES 2+ driverUSE_SDL2
(default: platform-dependent, usuallyON
) - Use SDL2 instead of older native device code
However, IrrlichtMt cannot be built or installed separately.
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.
