Error Compiling

[l1519066]

Hi,

So I managed to get the simple-wifi example working fine. However, my own main C code isn't compiling and I can't figure out why.

Code: Select all

#include <stdio.h>
#include <string.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/event_groups.h"
#include "esp_system.h"
#include "esp_wifi.h"
#include "esp_event_loop.h"
#include "esp_log.h"
#include "nvs_flash.h"

#include "lwip/err.h"
#include "lwip/sys.h"

#define DEFAULT_ESP_AP_SSID      "wifi"
#define DEFAULT_ESP_AP_PASS      "test123"
#define MAX_STA_CONN             1

wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
wifi_config_t wifi_config = {
  .ap = {
      .ssid = DEFAULT_ESP_AP_SSID,
      .ssid.len = strlen(DEFAULT_ESP_AP_SSID),
      .password = DEFAULT_ESP_AP_PASS,
      .max_connection = MAX_STA_CONN,
      .authmode = WIFI_AUTH_WPA_WPA2_PSK
  },
};
void app_main(){
  // Initializing WiFi
  esp_wifi_init(&cfg);
  esp_wifi_set_mode(WIFI_MODE_AP);
  esp_wifi_set_config(ESP_IF_WIFI_AP, &wifi_config);
  esp_wifi_start();
}

I understand that I don't have error checking in this. It's just a very simple version to get me going on how this stuff works. The errors are as follows

I'm using Ubuntu and no IDE - just Atom text editor and terminal. I used make clean and make flash to build it.
