    In my Qt project I linked libraries dynamically and project built and run successfully but when I click on pushbutton then program finished and give me error as undefined symbol: project source directory path:_Z16LMB_GPIO_GetInfoPhs. what is wrong is it compiler's error.

        How did you do that? Show us your *.pro file.

        undefined symbol

        You need to tell the OS where to find the library when the application is launched. See:
