Cant Compile on ESP32 dev module

[affix-development]

bug Cant compile a client example with Esp32 and W5500 module SPI interface.

Environment info

• IDE w/version [e.g Arduino IDE 1.8.12]
• Platform/Board: ESP32 dev module
• Network controller (shield or module): W5500 Module SPI

Expected behavior A clear and concise description of what you expected to happen.

Have you tried this: https://github.com/arduino-libraries/Ethernet/issues/88#issuecomment-455498941 ?

[affix-development]

I delete the Ethernet Library and its compile well.

But now I Cant connect with socketServer(Using as client scketch). And DHCP not works too.

I dont know what do now.

[skaarj1989]

You need an Ethernet library (try to reinstall it).
