Ok, so still points to HAL_ADC_MODULE_ENABLED not being defined. Select that text and 'Find-in-Files' within the project.

\STM32Cube_FW_F7_V1.11.0\Drivers\STM32F7xx_HAL_Driver\Src\stm32f7xx_hal_adc.c

&sharpifdef HAL_ADC_MODULE_ENABLED

..

&sharpendif

Should be in stm32f7xx_hal_conf.h

...

/* Define to prevent recursive inclusion -------------------------------------*/

&sharpifndef __STM32F7xx_HAL_CONF_H

&sharpdefine __STM32F7xx_HAL_CONF_H

&sharpifdef __cplusplus

 extern 'C' {

&sharpendif

/* Exported types ------------------------------------------------------------*/

/* Exported constants --------------------------------------------------------*/

/* ♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯ Module Selection ♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯ */

/**

  */

&sharpdefine HAL_MODULE_ENABLED

&sharpdefine HAL_ADC_MODULE_ENABLED

/* &sharpdefine HAL_CAN_MODULE_ENABLED */

Check defines in stm32f7xx_hal_conf.h pulling in #includes, and that the stm32f7xx_hal_adc.c file is in the project tree.

This is a linker error not a compilation error, so indicates the code behind the functions is missing.

Thanks for the answer, 

But i did add all the needed files in the project tree this problem keeps happening

I have zero visibility into your problem, the linker says they are not there.

If the file is not missing, then you'll need to look to see if there is some ♯ ifdef around them preventing the body code from being compiled.

Enable 'Browse Information', and right click 'Go To Definition Of ...' at the places where you call the functions.

i hope this makes it clear for you, i've been trying for hours , it's the LwIP project from the STM32cubemx applications
