OK, the amount of gotchas with unigine-superposition 1.0-6 benchmark is too damn high, which is a pity because it's awesome!!!
How to run Unigine Superposition Benchmark in ArchLinux
- download the Linux (.run) version of Qt5.9, the latest version that works https://download.qt.io/official_releases/qt/5.9/5.9.0/
- make it executable
chmod a+x qt-opensource-linux-x64-5.9.0.run
- run it
- skip the registration bit and when prompt about what to install, check Qt5.9 too (top checkbox) and don't change the default path (or do it and adjust following commands). You migt try to not install the tools and see how that goes.
- use yaourt or pakku / pamac to install
pakku -S --needed unigine-superpositionand I suggest you do that after a
sudo mount -o remount,size=20G,noatime /tmp. If it ends with an error, just
sudo pacman -U the-big-tar-file-in-tmp
- remove the Qt folder inside the unigine-superpos
