Gizmo64.plugin is working for me with Ubuntu 14.04 LTS.
I recently upgraded from Ubuntu 12.04 LTS to 14.04 LTS because people were seeing issues with Gizmo64.plugin compiled on 12.04.
Ubuntu 14.04 LTS is a more sensible support target for re-introduction of the Linux plugin.
Unfortunately the upgrade broke my dev setup. The plugin would no longer link.
A third party library was unhappy and required both source code and Makefile tweaks before I could recompile it with the 14.04 toolchain.
Gizmo64.plugin now compiles and links on Ubuntu 14.04 LTS
A memset() bug was found and fixed.
Linux behaves differently when we query the file system for the size of a file.
