Hi Christian, I tried to compile your code - it links and runs without a problem. I have a recent CVS tree of Root and g++-3.0.1 on Debian/Linux/ppc. I put the sources back to http://darbujan.fzu.cz/~masik/root/gui.tgz but I don't think I've changed anything apart from the local customization. cheers Jiri masik@pceple53:~/prog/root_jm/christian$ make -f Makefile4A g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include --no-rtti -fno-exceptions -c MyClassA.cxx Generating dictionary MyClassADict... g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include --no-rtti -fno-exceptions -c MyClassADict.cxx g++ -shared MyClassA.o MyClassADict.o -o libMyClassA.so masik@pceple53:~/prog/root_jm/christian$ make -f Makefile4A B g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include -c MyClassB.cxx Generating dictionary MyClassBDict... g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include -c MyClassBDict.cxx g++ -shared MyClassB.o MyClassBDict.o -o libMyClassB.so masik@pceple53:~/prog/root_jm/christian$ make -f Makefile4B[K[K g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include -c Mygui.cxx Generating dictionary MyguiDict.cxx... class TMyFrame in Mygui.h line 37 original base of virtual func g++-3.0 -Wall -fPIC -fsigned-char -I/data/masik/root-v3.02.opt.gcc3/include -c MyguiDict.cxx g++-3.0 -o Mygui Mygui.o MyguiDict.o \ -L. -lMyClassB -lMyClassA -L/data/masik/root-v3.02.opt.gcc3/lib -lCore -lCint -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lGui -lnsl -lm -ldl -rdynamic Mygui done masik@pceple53:~/prog/root_jm/christian$ ./Mygui
