Does the ''offending'' source file include a device-specific header like stm32fxxx.h ?

(''#include ''stm32f4xx.h'' in the case of STM32F4). Do you have the define ''USE_STDPERIPH_DRIVER'' added to your project settings ? Take closer look at a working example project, and try to understand how this StdPeriph_Lib headers are working.

everything is okay , even i got two projects from ST site and they work great , but when i copy one source code to the other project this error comes up , all the libraries are in the right path just it says ''no definition...'' so it seems like the compiler read the fonction but it didnt find its source  code

Did you check what I recommended - probably not ? Do you have the define ''USE_STDPERIPH_DRIVER'' added to your project settings ? Find the stm32f4xx.h file, open it in the editor, and search for the string '' USE_STDPERIPH_DRIVER''. If you look more closely, you will notice that stm32f4xx.h includes the stm32f4xx_conf.h file ONLY if this macro is defined. In my version at lines 7812 ff:

#ifdef USE_STDPERIPH_DRIVER
#include ''stm32f4xx_conf.h''
#endif /* USE_STDPERIPH_DRIVER */

The file stm32f4xx_conf.h in turn includes the StdPeriph_Lib headers, where all those missing structs etc. are defined. Hence you need to define this macro globally (for the whole project). The best place are the project/build settings. Of course you need to have such a file stm32f4xx_conf.h in your project. If necessary, copy one over from another project, and adapt it. Again: Take closer look at a working example project, and try to understand how this StdPeriph_Lib headers are working.

And BTW, you need to add the required/used StdPeriph_Lib source files to your project, too.

trust me it works and i tried it on my board , but when i copy an another working project on the same workspace i got this errors

ps: every library is inculded and nothing is missing

the two projects have the prerocessus and includes paths

Copying the files is not enough, you have to clone the project and retain the meta-data (include paths, defines, optimization, settings, etc) associated with the project.
