Unable to call to function vTaskList (GIT8266O-190)

[zinahe]

In trying to generate a run-time stat about running tasks, I tried to call vTaskList but it fails with the following error message:

undefined reference to `vTaskList'
collect2: error: ld returned 1 exit status

Based on a recommendation found in ESP32 forums I did try to enable it's use in components/freertos/include/freertos/FreeRTOS.h by setting
configUSE_TRACE_FACILITY and configUSE_STATS_FORMATTING_FUNCTIONS as follows

#ifndef configUSE_STATS_FORMATTING_FUNCTIONS
#define configUSE_STATS_FORMATTING_FUNCTIONS 1
#endif

#ifndef configUSE_TRACE_FACILITY
#define configUSE_TRACE_FACILITY 1
#endif

A similar issue can be found here

"configUSE_TRACE_FACILITY", "configUSE_STATS_FORMATTING_FUNCTIONS" and "configSUPPORT_DYNAMIC_ALLOCATION" should be set to be "1" at "FreeRTOSConfig.h".

I'm still unable to call vTaskList even with @donghengqaz solution. Those values are already set to 1 on my system

Using SDK of release/v3.1 or newer version, you can only enable at "make menuconfig":

Component config
    ---> FreeRTOS
          ---> Enable FreeRTOS trace facility
              ---> Enable FreeRTOS stats formatting function
