Compilation errors after upgrade from 2.3.4 to 2.3.5

[KenkiCK]

Describe the problem

After Upgrade the Arduino IDE I get compilation errors for the Heltec_ESP32_Dev-Boards library. Before the upgrade it works without problems.

To reproduce

Compile a heltec lora 32 (V3) board code.

#include <WiFi.h>
#include <PubSubClient.h>
#include <HT_SSD1306Wire.h>
void setup() {}
void loop() {}

Compilation fails:

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

I had a similar problem, I solved by downgrade the expressif board file from 3.2.0 to 3.1.3

Many thanks, I tried and it works for me too. Great and again, many thanks for you help.

Hey KenkiCK - I had the same problem. I decoded the error messages and fixed the problem by editing two of the include files:

1. sx1262-boards.c - at the top of this file, change the statement "lora_printf" to "log_printf"
2. radio.c - you have to add the standard Arduino include file: #include "Arduino.h"

When I made those two changes in the src/driver files, it fixed the compile problems.
