thank you, steinlee
perhaps i don't describe the program directly;
first,i compile the QT source package on ubantu;
second,i download a bin qt-creator install package;
then,when i compile my program ,recieved that " don't find libQtOpenGL.so",i tried to find it in QT source folder ,in fact ,it really no it ;but i find it in qt-creator's folder;so i copy it to qt's lib folder ,than it can go to next step ;
bu at last ,a new problem come as top i asked.
so i think the problem breaked when i complite the Qt source package,why it can't born the libQtOpenGL.so;
because i don't install OpenGL on Ubantu ???
