Hello,
My problem is this error.
I tried to fix it, but unfortunately i couldn’t because I don’t know exactly what the problem is
This is the error code:
.pio\build\esp32dev\src\web_control.cpp.o:(.literal._Z14httpClockSetupv+0x34): undefined reference to `webServer'
.pio\build\esp32dev\src\web_server.cpp.o:(.literal._Z7httpLogv+0x8): undefined reference to `webServer'
.pio\build\esp32dev\src\web_server.cpp.o:(.literal._Z16handleWebRequestv+0x8): undefined reference to `webServer'
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32dev\firmware.elf] Error 1
It seems like only web_control.cpp and web_server.cpp are affected so I’ll put the code too.
