RE: rootcint gives: Error: cannot open file "TROOT.h" :0:

Hi,

Also note that -I$ROOTSYS/include is not necessary since rootcint automatically uses it.

Cheers,
Philippe

Hi,

rootcint is as picky as some compilers: remove the space between -I and the path, i.e.

rootcint HepMCEventdict.cc -c \
-I../../2.0.2.2/CLHEP/HepMC/include/ -I$ROOTSYS/include/ HepMCEvent.h

should work.

Cheers, Axel.
