Base64 compile error with Arduino RP2040 Connect

[leopold-gravier]

Hello, Whenever I try to include ArduinoHttpServer on a project for an Arduino RP2040 Connect, it fails to compile.

Ex :

#include <ArduinoHttpServer.h>

void setup(){}
void loop() {}

Output :

In file included from C:\Users\L�opold\Documents\Arduino\libraries\ArduinoHttpServer\src/ArduinoHttpServer.h:10:0,
                 from C:\Users\Léopold\Documents\Associatif\Minotaure\Projet Initiation\Code\Test\Test.ino:1:

The error message with verbose enabled

I invastigated a bit and it seems very specific to the Arduino RP2040 Connect board, I tried compiling the same script for a regular Nano board and it worked fine.

It appears that another "base64.h" file is loaded. There is one such file inside the libraries specific to the RP2040 Connect board.

The exact path is C:\Users/[Your username]\AppData\Local\Arduino15\packages\arduino\hardware\mbed_nano\4.0.4\cores\arduino\mbed\connectivity\mbedtls\include\mbedtls\base64.h

System info : Windows 10 Arduino IDE 2.2.1 ArduinoHttpServer 0.10.1 Base64 1.0.0

I have the same issue with a ESP8266 board, which also has its own base64.h implementation in the core.

Try to #define ARDUINO_HTTP_SERVER_NO_BASIC_AUTH.

It will remove the need for the less-standard Base64 library.

Thank you for your answer @QuickSander :)

Although, is this flag implemented in the latest release ? I tried it with the latest release available on the arduino IDE (ArduinoHttpServer 0.10.0), but I had the same error when compiling.

#define ARDUINO_HTTP_SERVER_NO_BASIC_AUTH
#include <ArduinoHttpServer.h>

void setup(){}
void loop() {}

It is only when I installed the library manually using this repo that it worked.

Hi, yes it is indeed available in the version online: https://github.com/QuickSander/ArduinoHttpServer/blob/8bdc3d5a18c6a310ce3c9af62cce38e260f7c056/src/internals/StreamHttpRequest.hpp#L20

Do you have an option to specify the #define in Arduino IDE? In PlatformIO it compiles fine, but PlatformIO also defines it with value '1'.
