Linker complains that it can't get closure due to missing/undefined symbols.

Will need to add source files, or libraries, containing missing functions for build to complete successfully.​

The undefined symbols are referred from bitmapdatabase.o, which is the object of bitmapdatabase.cpp. I don't think that's a Cube file. Maybe it's a Touchgfx Designer file? If so, you're posting to the STM32 MCUs topic and maybe not many developers there know about it. You can add topics using the little down-arrow in the top right corner of your post.

Google found https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Projects/STM32469I_EVAL/Demonstrations/TouchGFX/Gui/generated/images/src/BitmapDatabase.cpp. Maybe something there will help?

What is the IDE? I always diff and fix the project files following a a Cube generate. Check for folders/files removed or excluded.

The IDE is MRK-IAR (keil)

As we are generating from cubemx it won't includes BSP files, so i have added BSP files also Still it is not working...If i use IAR am not getting any errors ,but again loading is done successfully,, But i can't sea anything on the screen the display itself swiched off...why?

Thank you.

Diff against working code or read or debug all the code to find why. Include IDE project files in the investigation. These are the files that tell the IDE what source files to build, where they are, the directories to search for includes, the libraries to link, etc etc. Cube modifies them if it thinks it's added or changed source files. I always inspect project files and often repair them after a generate. Don't assume anything works properly.
