Hello,

I'm trying to compile a therion config and am getting the following error:

therion: error -- PROJ4 library: -1 (no arguments in initialization list)

The repo and file I'm attempting to compile:

This works for for someone on OSX and another on Windows but not for me on Ubuntu 20.04. I tried searching for the error but there wasn't  anything enlightening.

It compiles if I comment out "epsg:3794" so I'm guessing perhaps my version of the proj library does not have this coordinate system? Could I build a more up to date version?

Can anyone point me in the right direction?

Thanks,

Rhys
