Error: undefined reference to - wrap_cyw43_cb_process_ethernet

I'm trying out platformio with raspberry picow. With simple example, everything works fine.

However, when I start importing external libraries (defined above), I run into compilation error.

Below is the platformio.ini file:

[env:stable]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = pico
framework = arduino
board_build.core = earlephilhower
lib_deps = 
    knolleary/PubSubClient@^2.8
    arcao/Syslog@^2.0.0
    fu-hsi/PMS Library@^1.1.0

includes are:

#include <Arduino.h>

// put function declarations here:
#include "PMS.h"
#include <WiFi.h>
#include <PubSubClient.h>
#include <Syslog.h>
//#include <WiFiClientSecure.h> //thought this was the problem so commented it, but didn't make any difference

Error when compiling:

Seems the issue is seen because of this method:

void establishWifi() {
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
     delay(500);
     Serial.print(".");
     delay(500);
  } 
}

If I comment this method out, the code compiles fine. Any clue what is wrong with wifi connection?

Seems I have figured out the issue:

[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = rpipicow
framework = arduino
board_build.core = earlephilhower
lib_deps = 
    fu-hsi/PMS Library@^1.1.0
    knolleary/PubSubClient@^2.8
    arcao/Syslog@^2.0.0

Had to use the board as board = rpipicow instead of board = pico. Will try and update the findings.

Closing this issue. The issue was with me setting the board incorrectly (it had to be set as rpipicow). Working platformio.ini:

[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = rpipicow
framework = arduino
board_build.core = earlephilhower
lib_deps = 
    fu-hsi/PMS Library@^1.1.0
    knolleary/PubSubClient@^2.8
    arcao/Syslog@^2.0.0
