Thanks for the quick answer. But I still need help: I did as requested, but cant get it linked: >>> TMyRint.H -------------- #ifndef TMyRint_H #define TMyRint_H #include <TRint.h> class TMyRint : public TRint { public: TMyRint(char* appClassName, int* argc, char** argv); void PrintLogo(); }; #endif >>> ------------------------- >>> TMyRint.C --------------- #include "TMyRint.H" TMyRint::TMyRint(char* appClassName, int* argc, char** argv) : TRint(appClassName, argc, argv, options, numOptions) {} void TMyRint::PrintLogo() {} >>> ------------------------- >>> and I get: eg++ -g -rdynamic \ mo.o mydict.o TMyRint.o 7of9.o Date.o EasyTableReader.o DBTableIterator.o StyledCanvas.o /afs/desy.de/group/hera-b/MIZZI/pro/Linux_intel/lib/mcshb.a -L/afs/desy.de/products/cern/root_gcc/lib -lNew -lBase -lCint -lRint -lClib -lCont -lFunc -lGraf -lGraf3d -lHist -lHtml -lMatrix -lMeta -lMinuit -lNet -lPostscript -lProof -lTree -lUnix -lZip -lg++ -lm -ldl -rdynamic -L/afs/desy.de/products/cern/root_gcc/lib -lNew -lBase -lCint -lRint -lClib -lCont -lFunc -lGraf -lGraf3d -lHist -lHtml -lMatrix -lMeta -lMinuit -lNet -lPostscript -lProof -lTree -lUnix -lZip -lGpad -lGui -lGX11 -lX3d -L/usr/X11R6/lib -lXpm -lX11 -lg++ -lm -ldl -rdynamic \ -o 7of9 TMyRint.o: In function `TMyRint type_info function': TMyRint.o(.text+0xb7): undefined reference to `TRint type_info function' TMyRint.o(.text+0xbf): undefined reference to `TRint type_info node' collect2: ld returned 1 exit status make: *** [7of9] Error 1 It seems, that I didnt understand something basic!?
