I don't know why the viewports are deleted with deleteLater(), but it leads to an OpenGL context getting deselected behind our back, and so we don't know when is a good time to re-select it. This leads to termination of the engine when selecting File->Close (Ctrl+W) in the editor, because the graphics re-initialization fails with no GL context active. Instead, just delete the viewport widget immediately, which works fine at least on Linux. This is also recommended by the Qt documentation at http://doc.qt.io/qt-5/qopenglwidget.html. |

README
Requirements
============
You should be able to build OpenClonk with any C++ compiler that supports
ISO C++14. That said, on Windows, we recommend using Microsoft Visual C++
2015 or higher; the Express edition will be sufficient. On Linux, you will
be fine with GNU g++ 4.9 or later. Apple users should use a clang-based
XCode version.
To generate project files for your chosen build system, you will also have to
install CMake from http://www.cmake.org/.
Additionally, OpenClonk depends on a number of third-party libraries:
- zlib (http://zlib.net/)
- libpng (http://www.libpng.org/pub/png/libpng.html)
- libjpeg-turbo (http://sourceforge.net/projects/libjpeg-turbo/files/)
- FreeType (http://www.freetype.org/)
- The OpenGL Extension Wrangler Library (http://glew.sourceforge.net/)
- FreeALUT (https://github.com/vancegroup/freealut)
- libogg and libvorbis (https://www.xiph.org/downloads/)
OS X Specific
=============
OpenClonk supports OS X versions 10.8 "Mountain Lion" and later.
If you are using brew (https://github.com/mxcl/homebrew) or MacPorts
(http://www.macports.org/), the packages you'll have to install are:
libjpeg, libpng, freetype, glew, libogg, libvorbis
Linux Specific
==============
For building OpenClonk on Linux, you need the following libraries in addition
to the ones listed above:
- GTK+ 3.4 or greater (http://www.gtk.org)
- libGL (http://www.mesa3d.org/)
- SDL 1.2 (http://www.libsdl.org/download-1.2.php)
- SDL_mixer 1.2 (http://www.libsdl.org/projects/SDL_mixer/release-1.2.html)
- libupnp
- libxrandr
Most distributions should provide these dependencies via their packaging
system. For Debian based distributions, you will need these packages:
build-essential cmake imagemagick libfreetype6-dev libgl1-mesa-dev
libglew-dev libgtk-3-dev libjpeg-dev libpng-dev libsdl1.2-dev
libsdl-mixer1.2-dev libupnp-dev libxrandr-dev x11proto-core-dev
zlib1g-dev libalut0
At least gcc-4.9 is required.
Windows Specific
================
In addition to the libraries above, you will need one more if you want to
target Windows:
- OpenAL Soft (http://kcat.strangesoft.net/openal.html)
To create an installer, you will also need the Nullsoft Install System
(http://nsis.sourceforge.net/). To create the installer, build the "setup" target.
