Error when trying to build mod

Hello,

I'm new to the modding community, I installed tModLoader and got a ModSkeleton.
I'm on Ubuntu 16.04.

When I press "Mod Sources" and press on "Build" it just shows an error, when I press open log it shows me This:

error : ERROR: ld.so: object '/home/phpyp/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

error : ERROR: ld.so: object '/home/phpyp/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so'...
