Hey! I just thought I would share a new experience - trying to setup my working environment on a fresh Fedora 23 installation. I recently installed Unity3D on Bunsenlabs Linux and sometimes I regret not documenting anything, especially when I actually solved problems to get it working. So far Fedora accepts Unity3D pretty well. I started by installing my nvidia-driver as a prerequisite. Proper hardware functionality was important for me and I don't know if I ever tried to install unity3d with nouveau. I downloaded the latest build #2016031701 (5.3.4f1) and moved it to ~/bin, extracted it to ~/bin/unity3d and tried to run Editor/Unity from the command line. Error. That was expected, since I could not really install the dependencies as easy as I could with Bunsenlabs (debian based) by just following the list of dependencies and throwing it at apt-get. I'm stuck with dnf and have to learn from the output Unity3d gives me. Code (bash): [user@localhost Editor]$ ./Unity ./Unity: error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory Well, let's find out where to get it: Code (bash): [user@localhost ~]$ dnf provides libpq.so.5 Last metadata expiration check: 1:09:24 ago on Thu Mar 24 14:35:44 2016. postgresql-libs-9.4.5-1.fc23.i686 : The shared libraries required for any PostgreSQL clients Quelle : fedora postgresql-libs-9.4.6-1.fc23.i686 : The shared libraries required for any PostgreSQL clients Quelle : updates First I installed the i686 package which didn't work, but Code (bash): sudo dnf install postgresql-libs did the trick. Unity3D started just fine and opened the splash screen. Sadly, the full-grey version that should've been fixed in this build! How can this be? I knew from my Bunsenlabs installation that the full-grey login screen was caused by a failed npm/nodejs job that didn't put a folder named unity-editor-home in the right npm-packages directory. So I realized that I'll have to install nodejs and npm. Code (bash): sudo dnf install nodejs npm Then I started Unity3D again and could watch it create new folders in my home directory. Seems like npm was working now, and I already found unity-editor home in /home/user/.local/share/unity3d/Packages/.npm. I attached a screenshot as a proof. I was quite surprised how easy the installation was. I'll update this thread to show what I do to integrate unity3D in my system. The unsupported installer does not create any .desktop files and does not solve dependencies, so there's still some stuff to do. One of the first things will be setting up Android Studio and Java 7 SDK to allow easy Android Game Development like I did on Linux Mint 17. I'll try to document everything, also to have a future reference for myself.
