i m working on a project in which i am using stm32f411 nucleo board. in which i face error Description Resource Path Location Type fatal error: ff.h: No such file or directory fatfs.h /New Folder/Inc line 56 C/C++ Problem

In file included from C:/Users/firmware/Desktop/uc4/New Folder/Inc/file_functions.h:10:0, from C:/Users/firmware/Desktop/uc4/New Folder/Inc/target_init.h:30, from C:/Users/firmware/Desktop/uc4/New Folder/Inc/Test_functions.h:20, from C:/Users/firmware/Desktop/uc4/New Folder/Inc/UC_Packet_Process.h:20, from C:/Users/firmware/Desktop/uc4/New Folder/Inc/system.h:15, from C:/Users/firmware/Desktop/uc4/New Folder/Inc/Analog_Light.h:15, from ../Src/Analog_Light.c:9: C:/Users/firmware/Desktop/uc4/New Folder/Inc/fatfs.h:56:10: fatal error: ff.h: No such file or directory #include "ff.h"

but the file ff.h is present at location middleware/third_party/FatFs/src

makes sure that path is included in the "include paths" used by the compiler. Or provide a relative path to that file specifically.

In Keil, you can click "Project->Options" then "c/c++" tab. Then you can look for the "Incl Paths" My project for example has the following:

"../Inc;v../Drivers/STM32L4xx_HAL_Driver/Inc; ../Drivers/STM32L4xx_HAL_Driver/Inc/Legacy; ../Drivers/CMSIS/Device/ST/STM32L4xx/Include;../Drivers/CMSIS/Include"

verify your middleware/third_party/FatFs/src (or my guess is you might have a match inc folder where the .h file is present). But anyways, find that file, make sure you include the file path so the compiler knows where to find it.

I don't know what tool you are actually using, but most tools have an option to add include paths.

  • Thanks for your answer .I am using eclipse tool. and in my peroject these was include before ../Inc ../Drivers/STM32F4xx_HAL_Driver/Inc ../Drivers/STM32F4xx_HAL_Driver/Inc/Legacy ../Middlewares/Third_Party/FatFs/src ../Middlewares/Third_Party/FreeRTOS/Source/include ../Middlewares/Third_Party/FreeRTOS/Source/CMSIS_RTOS ../Middlewares/Third_Party/FreeRTOS/Source/portable/GCC/ARM_CM4F ../Drivers/CMSIS/Device/ST/STM32F4xx/Include ../Drivers/CMSIS/Include – Prikshit Rana May 15 '20 at 11:53
