I guess the distribution version of ROOT/Linux has been compiled with GCC 2.7.x (or whatever is coming with RedHat 5.0) - this should lead to such kind of unresolved references. On our RedHat 5.0 nodes we have GCC 2.7.2.3 /home/murat>g++ -v gcc -v Reading specs from /usr/lib/gcc-lib/i386-unknown-linux/2.7.2.3.f.1/specs gcc version 2.7.2.3.f.1 Regards, Pasha. -------------------------------------------------------------------------------- stefan kluth writes: > > Hi, > > I downloaded Linux root 2.07, unpacked, went into root/test and said > "make": > > persil:~/root/test> make > g++ -O -Wall -fPIC -I/home/skluth/root/include -c Event.cxx > g++ -O -Wall -fPIC -I/home/skluth/root/include -c EventCint.cxx > g++ -O -Wall -fPIC -I/home/skluth/root/include -c MainEvent.cxx > g++ -Wl,-soname,libEvent.so -shared -g Event.o EventCint.o -o libEvent.so > g++ -g MainEvent.o Event.o EventCint.o -L/home/skluth/root/lib -lNew > -lBase -lCint -lClib -lCont -lFunc -lGraf -lGraf3d -lHist -lHtml -lMatrix > -lMeta -lMinuit -lNet -lPostscript -lProof -lTree -lUnix -lZip -lg++ -lm > -ldl -rdynamic -o Event > Event.o: In function `Event type_info function': > Event.o(.text+0x166c): undefined reference to `TObject type_info function' > Event.o(.text+0x1672): undefined reference to `TObject type_info node' > EventCint.o: In function `Track type_info function': > EventCint.o(.text+0x55ac): undefined reference to `TObject type_info > function' > EventCint.o(.text+0x55b2): undefined reference to `TObject type_info node' > collect2: ld returned 1 exit status > make: *** [Event] Error 1 > Exit 2 > persil:~/root/test> uname -a > Linux persil 2.0.33 #7 Sat Apr 11 04:37:43 PDT 1998 i686 unknown > persil:~/root/test> g++ -v > Reading specs from /usr/lib/gcc-lib/i486-linux/egcs-2.90.28/specs > gcc version egcs-2.90.28 980423 (egcs-1.0.3 prerelease) > > Am I doing something wrong? cheers, Stefan > > ---Stefan Kluth---------------Lynen Fellow----------------|\--|\------- > - LBNL, MS 50A 2160 - phone: +1 510 495 2376 - |/ |/ - > - 1 Cyclotron Rd. - fax: +1 510 495 2957 - |\/\|\/\|' - > ---Berkeley, CA94720, USA-----e-mail: SKluth@lbl.gov------|/\/|/\/|---- > >
