PlatformIO compiling error

[aleiei]

When I try to compile your example, PlatformIO get always this error:

Executing task in folder ESP32_CAM_RTSP: pio run <

I also tried to change path from: ../../../lwip/src/include/lwip/inet.h on arpa/inet.h file to lwip/inet.h but i just get more compilation errors !

Any suggestions ? Thanks in advance to everyone.

Problem found and solved! When downloading the Micro-RSTP library with PlatformIO, LinkedListElement.h is missing ! I simply added the library manually.
