So on my system I use ROOT and some other programs I use refer back to ROOT for their functions. Ever since a recent OS update none of them work.
What I suspect has happened is that the OS update messed with / updated my c++ compiler which now can’t read my ROOT. Everything else is just a consequence of that.
I installed my ROOT from Source, so what I suspect is that if I go back through those instructions and repeat the compiler-related steps I might get lucky and that will fix everything. What’s more likely though is that I’ll have to uninstall/reinstall the new ROOT and all my other programs that reference ROOT.
Have I missed anything? Is there a strategy I could use between those two extremes? Or something even less invasive to my system?
Yes, after a “major” upgrade of the operating system and / or the compiler, you need to configure and build everything from scratch again (i.e., ROOT and all your additional libraries and executables).
I bit of a bummer but not completely unexpected. So I don’t have to uninstall and reinstall everything, just redo the configuration and compiling steps of installing everything?
Okay, so I tried to just recompile my ROOT with the new compiler and I got the following errors that I don’t recognize. It gets to about 51% before it does this. Warning, it’s a lot but I think a lot of it repeats the basics.

Had to do a bunch of skipping as it’s too many characters but I think there’s enough here to get the gist. Starting to think I’ll have to do sone uninstall and reinstall afterall.
Any help would be appreciated.
Hi @Jason_Forson ,
those compilation errors look weird Especially considering that Ubuntu 21.10 should just work. Did you delete the contents of the build directory before reconfiguring and rebuilding, i.e. is it an incremental build or a build from scratch?
Also consider installing a pre-built packages, e.g. via conda or snap, see Installing ROOT - ROOT .
Come to think of it, I had not. I’ve since then done a full uninstall-reinstall that seems to be working just fine but in hindsight that would have made things easier.
