Tfile.h no such file or directory

[jadimtz13]

I need help, it is the first time I use root, I installed it correctly in ubuntu 18, the root version is 6.18, I am trying to make root work with pythia through this line in a makefile:

histpkp: histpkp.cc
g++ -I/home/jadi/software/pythia/pythia8310/include root-config --cflags @.cc -o @ -lpythia8 -L/home/jadi/software/pythia/pythia8310/lib root-config --glibs

and it gives me the error:

make histpkp
g++ -I/home/jadi/software/pythia/pythia8310/include root-config --cflags histpkp.cc -o histpkp -lpythia8 -L/home/jadi/software/pythia/pythia8310/lib root-config --glibs
histpkp.cc:2:10: fatal error: Tfile.h: no such file or directory
#include “Tfile.h”
^~~~~~~~~
compilation terminated.

Dear @jadimtz13 ,

Are you sure your environment has a working ROOT installation? Can you check that

$: root

Starts a ROOT prompt as expected?

After that, judging by the error you posted from above

histpkp.cc:2:10: fatal error: Tfile.h: no such file or directory
#include “Tfile.h”

Is this a typo? Or are you actually writing "Tfile.h" in your program? The correct header name is TFile.h with a capital F.

Cheers,
Vincenzo
