    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 ♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯♯ */

    /**

      * @brief This is the list of modules to be used in the HAL driver

      */

    &sharpdefine HAL_MODULE_ENABLED

    &sharpdefine HAL_ADC_MODULE_ENABLED

    /* &sharpdefine HAL_CAN_MODULE_ENABLED */

    /* &sharpdefine HAL_CAN_LEGACY_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.

    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.
