Hi,

I'm trying to add TGraph2D and TGraph2DErrors classes to my ROOT.jl using ROOT.jl-generator. I added the coresponding header files to ROOT.wit.in and tried to generate and compile ROOT.jl using the genandbuild.sh script. Unfortunately I got this error:

Failed to precompile ROOT [1706fdcc-8426-44f1-a283-5be479e9517c] to "$HOME/.julia/compiled/v1.11/ROOT/jl_rpYWce".
C++ exception while wrapping module ROOT: No appropriate factory for type 11TTreeReader
ERROR: LoadError: No appropriate factory for type 11TTreeReader

I tried the compilation without the added header files and I also tried different ROOT versions, but nothing helped.
My current setup is:

• Julia 1.11.3 (2025-01-21)
• ROOT 6.30/04 (Built for linuxx8664gcc on Apr 28 2024, 20:44:39)
