Hi,
i am attempting to update the unity3d package to the newest 2019 LTS version myself.
After forking and changing the upstream URL, checksum and version my default.nix looks like this:
{ stdenv, lib, fetchurl, makeWrapper, file, getopt
, gtk2, gtk3, gdk-pixbuf, glib, libGL, libGLU, nss, nspr, udev, tbb
, alsaLib, GConf, cups, libcap, fontconfig, freetype, pango
, cairo, dbus, expat, zlib, libpng12, nodejs, gnutar, gcc, gcc_32bit
, libX11, libXcursor, libXdamage, libXfixes, libXrender, libXi
, libXcomposite, libXext, libXrandr, libXtst, libSM, libICE, libxcb, chromium
, libpqxx, libselinux, pciutils, libpulseaudio
}:
let

Then i built and installed the package locally.
When starting i get: /nix/store/hckbh75viicjf0nd8w1zmf88gb0nry21-unity-editor-2019.2.19xf1/opt/Unity/Editor/Unity: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory

Has anyone more experience on how to resolve this?
Thanks in advance.
