I am trying to run the example problems and have gotten both A01 and N01 to compile fine. I closed cygwin and tried to recompile and now get errors saying that it is looking for a file: c:/geant4/geant4_7_0/config/sys/.gmk and can't find it also later it looks for CLHEP/HepMC/GenEvent.h and can't find it Can you give me a hint at the fix???
Please check that you have the proper variables (G4INSTALL, CLHEP_BASE_DIR, etc...) defined in your environment at the time you try building the example...
