Hello,
We are usig the W5500 in a board, it is driven by an STM32F303. This MCU and the W5500 are used with MBED, we selected the W5500 also for this reason. However, i face a strange issue with the library, when i import it to the MBED project (locally, compiled with the MBED CLI) i get a bunch of recursion errors, all i do is to drop the library folders : W5500Interface and WebSocketClient into the project folder, for main.cpp i used directly the websocket example found here:W5500 | Mbed
Here is the ouput when i try to compile :
iMac-de-Hoel-2:mbed-os-example-blinky hoel$ mbed compile -m LORAM3_F303CC -t GCC_ARM

The blinky project compiles fine when the library is removed.
If some user or support can point to the issue that would be much appreciated, deadline is close and i ddint expected this kind of compilation problems with the example.
Thank you.
