Error compiling ethernet example for w5500-evb-pico RP2040 on win10

I'm trying to compile Ethernet example for w5500-evb-pico on win10 with following platformio.ini Any idea why this happening?

Sorry, this is a library issue and not related to the core. You're using a 3rd party Ethernet, HTTPClient, and WebServer. Not the core's versions of them AFAICT from your logs. I suggest paring things down to a single 3rd party lib at a time, and if those fail opening bugs in the appropriate repo. Good luck!

PIO + regular Ethernet library is definitely possible, we discussed that in https://github.com/earlephilhower/arduino-pico/discussions/1169 with e.g. the sketch https://gist.github.com/maxgerhardt/a33206a8e76ee6c0b66d574c4a1ad1e8.

So https://github.com/arduino-libraries/Ethernet/blob/master/examples/WebServer/WebServer.ino should work too with a Ethernet.init(17); // WIZnet W5100S-EVB-Pico W5500-EVB-Pico adjustment.

Just a heads up on why that error is happening: The EthernetWebServer also has src/libb64/base64.h which interferes with the base64.h found in this core, so that's a game-over.

I've corrected the library and uploaded a minimally compiling project.

I also corrected the platformio.ini to board = wiznet_5500_evb_pico, because why use pico when we have dedicated board definitions for it?

Does it work during runtime? I don't know, I don't have that board.

i should have used this correctly. Thanks @maxgerhardt !
