I get this Error, while trying to run C and wasm code (using wasm3) on an raspberrypi using platformio:
I am using a RaspberryPi 3 Model B with Raspian I program in Visual Studio Code on the Raspberry I installed PlatformIO as Extension in VS Code
Probably there is an issue with libc?

====================== [FAILED] Took 4.48 seconds ======================
I already tried to add build_flags = -lm or lib_ldf_mode = chain+ to platformio.ini
I just commented out the lines in the m3_exec.h file. Seems like PlattformIO doesn't like floats in combination with wasm3.
