Go+Windows+Audio

[Dmitry Shumkov]

Hi all.

I've tried to get access to Windows audio from Go program but failed. That I did below:

1. Downloaded and built Portaudio (it's open audio I/O library http://portaudio.com/). So I've built that with Visual Studio and got .dll file.

2. Downloaded Go wrapper for Portaudio - ( github.com/gordonklaus/portaudio ) 

3. Made simple Go file with an example from wrapper above to test.

4. Go build.

So Go couldn't build that. As far as I understand that's tried to build the portaudio from source with cgo. I've installed MinGW (gcc for Windows) and pkg-config but last one can't find portaudio-2.0.pc file. Once I've renamed portaudio-2.0.pc.in to portaudio-2.0.pc however it shows gcc error: "gcc: error: @THREAD_CFLAGS@: No such file or directory". So I think it was stupid idea.

Hello, im now facing this same problem, did you managed to solve it?

[Tobias Wellnitz]

Alberto,

I'm using Docker for cross-compiling my cgo apps. One project of mine (remoteAudio) requires portaudio (and a couple of other C libraries like pkgconfig and libopus).

 

You can find the cross-compilation chain at github.com/dh1tw/remoteAudio-xcompile. For Windows, have a look at the windows-amd64 folder.

I have also written a companion blog post about cross compiling CGO projects.

Best regards, 

Tobias
