ld.lld: error: undefined hidden symbol: __math_invalidf

[funkycode]

I built tinygo from source as per official documentation (on gentoo here) tried to run ping pong example on nicenano

$ sudo ~/go/bin/mecha flash -i wazero -m nicenano
Building TinyGo module ping

btw i tried to do use only tinygo and wazero and get the same results

$ tinygo version                                                                                                                                                                                                          
tinygo version 0.31.2 linux/amd64 (using go version go1.22.2 and LLVM version 17.0.1)

Hello @funkycode thanks for the report. I think this is actually related more to your TinyGo custom build than Mechanoid itself.

Can you flash the normal blinky1 program on your board?

tinygo flash -target nicenano examples/blinky1

Perhaps you can open an issue in the TinyGo repo to resolve. It might require some docs update for gentoo? Not sure on that one.

Tinygo does work in general, but not with wazero/wasm host. Will open ticket there 🙏🏽

please notice the wazero team currently is not actively maintaining support for this type of cross-build, we merely assisted the mechanoid team to upstream their patches ;)

Sorry if I was unclear. I doubt it is anything specific to Wazero, rather is something to do with the custom TinyGo install. I meant to suggest opening issue in TinyGo repo, not Wazero repo.
