Bug? ESP8266WiFi + MFRC522 error

[ilpesce]

Hello and thanks in advance to all
I'm trying to use the libraries "rESP8266WiFi and "rMFRC522" along with an ESP-12E module device.
if you use rESP8266WiFi is ok
if you use rMFRC522 is ok
if you use rESP8266WiFi + rMFRC522 is compilation error ...
it is sufficient to enter the libraries, even without code

error

I've tried it with this code and it compiles successfully:

Sub Process_Globals
   Public Serial1 As Serial
   Private wifi As ESP8266WiFi
   Private mfr As MFRC522
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
End Sub

I found the problem. I fixed this issue when support for ESP8266 was added and forgot to upload the updated library.

Please download it again (v1.01): https://www.b4x.com/android/forum/threads/mfrc522-rfid-reader-writer.67160/
