STM32 NUCLEO-144: compiling failed

[EasyNetDev]

Hi,

I'm trying to compile OpenMRNLite on STM32 Nucleo-144 and the compiler is complaining that is not finding netdb.h file. I've tried to find this file, but I don't know if is another library which is providing it.
Here is the output:

In file included from C:\Users\Adrian\Documents\Arduino\libraries\OpenMRNLite-0.1.1\src\freertos_drivers\esp32\Esp32WiFiManager.hxx:45,
                 from C:\Users\Adrian\Documents\Arduino\libraries\OpenMRNLite-0.1.1\src\freertos_drivers\esp32\Esp32WiFiManager.cpp:35:

      |          ^~~~~~~~~

exit status 1
Error compiling for board Nucleo-144.

Any ideas?

If you are compiling for the STM32 nucleo, you should probably not be including the ESP32 wifi driver (that's for a different chip). What is the target / example application you were trying to compile?

Hi,

I was thought about that, but I didn't add any drivers for ESP32 WiFi.
Here is the code I'm trying to compile:

#include <cmsis_os.h>
#include <croutine.h>
#include <event_groups.h>
#include <FreeRTOS.h>
#include <FreeRTOSConfig.h>
#include <FreeRTOSConfig_Default.h>
#include <list.h>
#include <mpu_prototypes.h>
#include <portmacro.h>
#include <queue.h>
#include <semphr.h>
#include <stack_macros.h>
#include <STM32FreeRTOS.h>
#include <stream_buffer.h>
#include <task.h>
#include <timers.h>

#include <LwIP.h>
#include <OpenMRNLite.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Very basic compilation to check if the libs are ok. Even if I'm removing everything for RTOS is still failing with same error. Just load lwip.h and openMRNlite.

Kind regards,
Adrian

Aha, it seems that we have a .cpp file which is specific to the esp32 but it is being compiled under all targets. add an #ifdef ESP32 ... #endif around the entire contents of OpenMRNLite-0.1.1\src\freertos_drivers\ esp32\Esp32WiFiManager.cpp We'll have to upstream that ifdef but this will get you going faster.

I'll add that to my open PR for the same file...

Hi,

Thanks for the fix. Is not giving anymore this error, but I'm receiving this error:
