"expected identifier before '(' token" error during build

Posted by tayfuntatar on 2020-03-17 11:23

I am building a project which is a slightly modified version of BLE_Sample_App provided by ST. Before my last modifications, the IDE was succesfully building it. However, when I added some new functionality to the main code and added a couple of new source&header files, the IDE started complaining about line104 of stm32l4xx_hal_gpio.h, which is the definition of GPIO_PIN_2. The corresponding code part is below:

/* Exported constants --------------------*/
/** @defgroup GPIO_Exported_Constants GPIO Exported Constants
* @{
*/
/** @defgroup GPIO_pins GPIO pins
* @{
*/

  1. define GPIO_PIN_0 ((uint16_t)0x0001) /* Pin 0 selected */
  2. define GPIO_PIN_1 ((uint16_t)0x0002) /* Pin 1 selected */
  3. define GPIO_PIN_2 ((uint16_t)0x0004) /* Pin 2 selected */
  4. define GPIO_PIN_3 ((uint16_t)0x0008) /* Pin 3 selected */
  5. define GPIO_PIN_4 ((uint16_t)0x0010) /* Pin 4 selected */
  6. define GPIO_PIN_5 ((uint16_t)0x0020) /* Pin 5 selected */
  7. define GPIO_PIN_6 ((uint16_t)0x0040) /* Pin 6 selected */
  8. define GPIO_PIN_7 ((uint16_t)0x0080) /* Pin 7 selected */
  9. define GPIO_PIN_8 ((uint16_t)0x0100) /* Pin 8 selected */
  10. define GPIO_PIN_9 ((uint16_t)0x0200) /* Pin 9 selected */
  11. define GPIO_PIN_10 ((uint16_t)0x0400) /* Pin 10 selected */
  12. define GPIO_PIN_11 ((uint16_t)0x0800) /* Pin 11 selected */
  13. define GPIO_PIN_12 ((uint16_t)0x1000) /* Pin 12 selected */
  14. define GPIO_PIN_13 ((uint16_t)0x2000) /* Pin 13 selected */
  15. define GPIO_PIN_14 ((uint16_t)0x4000) /* Pin 14 selected */
  16. define GPIO_PIN_15 ((uint16_t)0x8000) /* Pin 15 selected */
  17. define GPIO_PIN_All ((uint16_t)0xFFFF) /* All pins selected */

  1. define GPIO_PIN_MASK ((uint32_t)0x0000FFFF) /* PIN mask for assert test */


What I don’t get is, why it is giving an error only for GPIO_PIN_2? I checked the other places this definition is used, but in those two other places, the new definitions are also legit. Finally, below is the console output when I try to build my project:

It would be great if anyone could help me with this.
