build error: resampleWriter does not implement WriteCloser[PCM16Sample] (missing method String)

[oofp]

Hello,

I just clone the project and followed the build instruction

I encountered the following error likely by a breaking change in one of the dependencies:

/mage build

Thank you!

I have the same problem – did you find a solution @oofp?

Found the solution in comment livekit/sip#420 (comment)

After running export CGO_ENABLED=1 and then mage build there was an error because gcc was not installed in the VM I'm running the server. I installed gcc and I was able to run mage build without problems after that
