this is the program the same autoconnect program
void setup() {
Serial.begin(115200);

WiFiManager wifiManager;
wifiManager.autoConnect("AutoConnectAP");
Serial.println("connected...yeey :)");

}

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

}

Getting error:

I was having this issue with the examples as well.
To fix it I replaced

#if defined(ESP8266)
#include <ESP8266WiFi.h>          //https://github.com/esp8266/Arduino
#else
#include <WiFi.h>          //https://github.com/esp8266/Arduino
#endif

//needed for library
#include <DNSServer.h>
#if defined(ESP8266)
#include <ESP8266WebServer.h>
#else
#include <WebServer.h>
#endif
#include <WiFiManager.h>         //https://github.com/tzapu/WiFiManager

With

#include <WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>

I have the same issue. @bobermen1 which library/file did you edit?

I got around this problem by changing lines 4-13 of
C:\Users\dc\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.0\libraries\WebServer\src\HTTP_Method.h

from

typedef enum {
  HTTP_GET     = 0b00000001,
  HTTP_POST    = 0b00000010,
  HTTP_DELETE  = 0b00000100,
  HTTP_PUT     = 0b00001000,
  HTTP_PATCH   = 0b00010000,
  HTTP_HEAD  = 0b00100000,
  HTTP_OPTIONS = 0b01000000,
  HTTP_ANY     = 0b01111111,
} HTTPMethod;

to

typedef enum {
  HTTP_GET     = 0b00000001,
  HTTP_POST    = 0b00000010,
  HTTP_DELETE  = 0b00000100,
  HTTP_PUT     = 0b00001000,
  HTTP_PATCH   = 0b00010000,
  HTTP_HEADWS  = 0b00100000,
  HTTP_OPTIONS = 0b01000000,
  HTTP_ANY     = 0b01111111,
} HTTPMethod;

This is a total hack, but it works because the enum value HTTP_HEAD doesn't seem to be used by esp32-WebServer.
