AliSLR as I mentioned I built TVH on Ubuntu 22.04 (I use the LTS version of Ubuntu every time so no urgency to upgrade to Ubuntu 24.04). There may well be changes to the Ubuntu 24.04 v Ubuntu 22.04 repositories that I’m not aware of.
In case things have changed could you enter the following in a Terminal session
sudo apt install gcc
and post the output here.
@DeltaMikeCharlie i’d like to try and help users, particularly those who are new to compiling TVH from source through the process I created a while back and keep it updated and relevant so I value their feedback as it benefits others.
Of course if we were to draw the build/compilation process to its logical conclusion we’d be using the method outlined in the TVH documentation
