Garfield ++ doesn't visualize: Aborted (core dumped)

[toygarzeki]

I use WSL (Ubuntu 20.04.6) for Root and Garfield++. The build was succesful, then I tried to run example/Gem. It gave some values but did not show up Root visualization and gave this error:

terminate called after throwing an instance of ‘std::logic_error’
what(): basic_string::_M_construct null not valid

Do anyone know why this happens? Thanks a lot in advance.

Hi,
did you set the GARFIELD_INSTALL environment variable?
