Build error : "syscall/js: build constraints exclude all Go files"

[ofauchon]

Hi, I could not build the project from latest sources:

go version go1.15.6 linux/amd64

$ go install -v ./...
package github.com/g3n/engine/util/wasm
	imports syscall/js: build constraints exclude all Go files in /usr/lib/go/src/syscall/js

Any idea how to solve that ?

Thx
Olivier

it appears that setting the GOOS and GOARCH variables resolves this problem albeit with some other arising.

GOOS=js GOARCH=wasm go install ./...

@ofauchon I added a build tag to exclude that file for non js/wasm builds - please try again with latest and let me know.

current master branch errors for me on wasm build.

g3nd git:(master) GOOS=js GOARCH=wasm go install ./...
package github.com/g3n/g3nd
        imports github.com/g3n/g3nd/app
        imports github.com/g3n/engine/audio/al: build constraints exclude all Go files in /Users/apple/workspace/go/pkg/mod/github.com/g3n/engine@v0.1.1-0.20210609173700-de78e3c4204a/audio/al

tinygo, just for the curiosity...

g3nd git:(master) tinygo build -o wasm.wasm -target wasm ./main.go
app/app.go:9:2: package runtime/trace is not in GOROOT (/Users/apple/Library/Caches/tinygo/goroot-go1.16.5-e918ea40337b026a7236a204272e89fff505c38957c9c688ab20baccf3be8219/src/runtime/trace)

Getting the audio working for browsers is likely a large amount of work.
So, for now, could we add the compile time flag of !wasm to github.com/g3n/engine/audio/al ?

Hi @danaugrs

I could compile g3n from today's master branch.

Thanks.

Great!
