Hello ROOTers. I've just installed ROOT 3.00/06 on my computer. I tried to compile the test programs and I get the following errors g++ -O -Wall -fPIC -D_REENTRANT -I/opt/cern/root/include -c Event.cxx g++ -O -Wall -fPIC -D_REENTRANT -I/opt/cern/root/include -c EventDict.cxx g++ -shared -O Event.o EventDict.o -o libEvent.so libEvent.so done g++ -O -Wall -fPIC -D_REENTRANT -I/opt/cern/root/include -c MainEvent.cxx g++ -O MainEvent.o libEvent.so -L/opt/cern/root/lib -lCore -lCint -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lm -ldl -lpthread -rdynamic \ -o Event MainEvent.o: In function `main': MainEvent.o(.text+0x799): undefined reference to `TNetFile::TNetFile(char const *, char const *, char const *, int, int)' MainEvent.o(.text+0x817): undefined reference to `TFile::TFile(char const *, char const *, char const *, int)' MainEvent.o(.text+0xaf4): undefined reference to `TNetFile::TNetFile(char const *, char const *, char const *, int, int)' MainEvent.o(.text+0xb7d): undefined reference to `TFile::TFile(char const *, char const *, char const *, int)' MainEvent.o(.text+0xc9e): undefined reference to `TDirectory::TDirectory(char const *, char const *, char const *)' collect2: ld returned 1 exit status make: *** [Event] Error 1 when I try other targets (I did not go though all) I get similar errors, though Tetris compiled fine but does not run. I get after .L Tetris.so dlopen error: /opt/cern/root/test/./Tetris.so: undefined symbol: Print__4TPadPCcT1 Load Error: Failed to load Dynamic link library /opt/cern/root/test/./Tetris.so *** Interpreter error recovered *** If I use one of my own classes, everything compiles fine. I am using gcc version 2.95.3 19991030, on Linux Mandrake 7.2 (Odyssey) My path, ROOTSYS and LD_LIBRARY_PATH are all properly set. ============================================================================== Ray Fliller: rfliller@bnl.gov Office Phone: (631)-344-6124 C-A Accelerator Physics Building 911 Brookhaven National Lab Upton, NY 11973 Office: Room 211 ==============================================================================
