英文:
Error using a RaspberryPi with PlatformIO and Wasm3
问题
我在尝试在树莓派上使用wasm3运行C和wasm代码（使用wasm3）时遇到了这个错误，使用platformio：
我使用的是带有Raspian的RaspberryPi 3 Model B。
我在树莓派上使用Visual Studio Code进行编程。
我在VS Code中安装了PlatformIO扩展。
可能与libc有关吗？
我已经尝试添加build_flags = -lm或lib_ldf_mode = chain+到platformio.ini文件中。
英文:
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?

I already tried to add build_flags = -lm or lib_ldf_mode = chain+ to platformio.ini

我刚刚在m3_exec.h文件中注释掉了这些行。
似乎PlattformIO不喜欢将浮点数与wasm3结合使用。
英文:
I just commented out the lines in the m3_exec.h file.
Seems like PlattformIO doesn't like floats in combination with wasm3.
