Hi,
from some weeks already, I cannot compile anymore my own software which was working well 1 month ago.
Even the simple demo version here cannot be compile anymore. Seems some issues with some dependent libraries.
Always got undefined reference:
c:/users/gfama/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/gcc8_4_0-esp-2021r2-patch3/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:\Users\gfama\OneDrive\Documents\Arduino\libraries\ESPAsyncWebServer-master\src/AsyncWebSocket.cpp:1273: undefined reference to SHA1Update'** c:/users/gfama/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/gcc8_4_0-esp-2021r2-patch3/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:\Users\gfama\OneDrive\Documents\Arduino\libraries\ESPAsyncWebServer-master\src/AsyncWebSocket.cpp:1274: undefined reference to SHA1Final'

C:\Users\gfama\OneDrive\Documents\Arduino\libraries\ESPAsyncWebServer-master\src/WebAuthentication.cpp:73: undefined reference to `mbedtls_md5_starts'

Any idea ? I tried to downgrade board ESP32, all dependent libraries, cannot find the reason.

Thanks,

Laurent
