Hi Yonggang! I encountered the exact same error when I tried to compile Gate 5.0.0... (could not find libGate.so). I noticed that the compilation of the subdirs (arf, physics, management etc) was ok and that all those .o-files ended up in my G4INSTALL directory under G4INSTALL/tmp/Linux-g++/Gate. If you open the GATE GNUMakefile that you run you see that G4TMP and G4BIN paths are set to your working directory by default (at least for me): G4WORKDIR/tmp G4WORKDIR/bin When compiling I think it looks there for the just created .o-files! Anyway, I changed those paths to G4INSTALL/tmp G4INSTALL/bin In all the subdirs (arf, physics etc) there's another makefile where G4TMP and G4BIN are defined again (don't know why!). I simply commented those commands so I only had to set them in the main make-file and everything compiled without problems for me... Good luck!
