undefined symbol: os/signal.signal_enable when compiling with TinyGo WASI target

[Mossaka]

Hi,

I tried compiling mcp-go using the latest version of TinyGo with the wasi / wsaip2 target, but ran into the following linker errors:

wasm-ld: error: lto.tmp: undefined symbol: os/signal.signal_enable  
wasm-ld: error: lto.tmp: undefined symbol: os/signal.signal_recv

I came across a similar issue that was previously closed as resolved, but I’m still hitting this with the current setup. Any guidance or workaround would be much appreciated!

Thanks!

@Mossaka that link to mcp-go did not work.

Can you please link to the specific code you were trying to compile and what command you used to compile it with so I can reproduce?

[Mossaka]

Yes, I was trying to compile this repo: https://github.com/mark3labs/mcp-go

[deadprogram]

Which code in that repo did you try, and what command did you use to try to compile it?

[Mossaka]

Synced up with @deadprogram online. The code I was trying is examples/everything.

The os/signal package expects those functions to be defined by the runtime. Currently those functions for tinygo on Linux and Darwin.
