Dictionary errors when using ROOT as a library after moving binary

[beojan]

I’m using ROOT as a library (with CMake) and generating a dictionary. If the directory is moved before running (because I’m running on the Grid, and PanDA doesn’t preserve the working directory name between the build and run jobs), I get errors:

Hi,

ROOT needs in your case to parse at runtime some headers. You can point ROOT to their position with the ROOT_INCLUDE_PATH environment variable, which can be formatted as LD_LIBRARY_PATH, i.e. with paths separated by :.

Cheers,
