Yeah, the ROOT geometry stuff is extremely bad - and to think this terrible interface is at the core of our simulations... Can we just drop ROOT Geo and just...

Hello! First thing to check, can you use the script included with root that sets the environment variables? That should be ` /Software/root/v6-28-02_Binaries/bin/thisroot.sh` or similar.

There can be several things. Does the installer find other root includes, i.e. did it build some parts and later failed on the TGX11? If so, you might have build...

Hm. Assuming you've imported your root version, such that ` which root-config` should point at `/Software/root/v6-28-06_Binaries/bin/root-config`: If you do ```bash root-config --features ``` Does the output include `x11`? It should...

Okay, next steps: - Does `root-config --incdir` point to the right directory, and is there a `TGX11.h`? - Do other parts of hdtv which require root compile, e.g. in the...
