Can't find'.hxx' files when compiling

ROOT

The root compiler can’t find’.hxx’ files when compiling.
But it works when I delete the #include lines

fatal error: 'RDataFrame.hxx' file not found
#include "RDataFrame.hxx"

make sure to source thisroot.sh before compiling your code

I source ....../bin/thisroot.sh in .zshrc.
And I just tried to source it manully before compiling. Still can’t find hxx files.

How do you compile your code? Are you using root-config --cflags, or at least root-config --incdir?

5

I just run my code by
root -q -l -b analyse_t0.cpp

Then you don’t compile it… And I found the issue it should be #include "ROOT/RDataFrame.hxx"
