I am using the Arduino BSEC Software Library @ 1.8.1492 with a ESP32 in PlatformIO without any problems.
With a seeed_xiao_esp32c3 i get the following linker error:
Linking .pio\build\seeed_xiao_esp32c3\firmware.elf
c:/users/xxxxxxxx/.platformio/packages/toolchain-riscv32-esp/bin/../lib/gcc/riscv32-esp-elf/8.4.0/../../../../riscv32-esp-elf/bin/ld.exe: cannot find -lalgobsec
Is there an update in a few time to support ESP32C3?
Thanks in advvance from Dieter Welter
