It does not compile

[digitalwm]

Hi, I just pulled the complete repo and tried to build it.

It gets some weird errors in regards with the Ethernet Library.

In file included from .piolibdeps\Ethernet_ID872\src\EthernetClient.cpp:22:0: .piolibdeps\Ethernet_ID872\src\Ethernet.h:258:2: error: invalid abstract return type 'EthernetClient' EthernetClient available(); ^ .piolibdeps\Ethernet_ID872\src\Ethernet.h:214:7: note: because the following virtual functions are pure within 'EthernetClient': class EthernetClient : public Client { ^ In file included from C:\users\dan\.platformio\packages\framework-arduinoespressif32\cores\esp32/Arduino.h:157:0, from .piolibdeps\Ethernet_ID872\src\EthernetClient.cpp:21: C:\users\dan\.platformio\packages\framework-arduinoespressif32\cores\esp32/Client.h:31:17: note: virtual int Client::connect(IPAddress, uint16_t, int) virtual int connect(IPAddress ip, uint16_t port, int timeout) =0; ^ C:\users\dan\.platformio\packages\framework-arduinoespressif32\cores\esp32/Client.h:32:17: note: virtual int Client::connect(const char*, uint16_t, int) virtual int connect(const char *host, uint16_t port, int timeout) =0; ^ In file included from .piolibdeps\Ethernet_ID872\src\EthernetClient.cpp:22:0: .piolibdeps\Ethernet_ID872\src\Ethernet.h:259:2: error: invalid abstract return type 'EthernetClient' EthernetClient accept(); ^ In file included from .piolibdeps\Ethernet_ID872\src\EthernetServer.cpp:22:0: .piolibdeps\Ethernet_ID872\src\Ethernet.h:258:2: error: invalid abstract return type 'EthernetClient' EthernetClient available();

Any hints will be welcomed :)

Hi @digitalwm,

I just dropped the repository into a clean directory and tried to build it, with exactly the same failure.

It seems like this is a problem with the latest Espressif library, referenced in issue #2755 ...and it seems to be affecting quite a lot more than just the Ethernet library, so we should hopefully see a quick fix.

Thanks for the heads-up on this issue, Dan.
