Does not compile for RISC-V architecture

[MatejKovacic]

Crosscompiling (GOOS=linux GOARCH=riscv64 go build -o MyApp-riscv) throws an error:

package MyApp
	imports github.com/gordonklaus/portaudio: build constraints exclude all Go files in /home/matej/go/pkg/mod/github.com/gordonklaus/[email protected]

Possibly you have CGO_ENABLED=0.

[MatejKovacic]

It seems so.

However, if I run CGO_ENABLED=1 GOOS=linux GOARCH=riscv64 go build -o MyApp-riscv, I get this:
