go-webkit2 wont compile with go 1.3

[mdimec4]

Hi
I have problem compiling go-webkit2 with new Go 1.3 compiler.
Go 1.3 has corrected a cgo bug that some C code binding libs seam to depend on.
http://golang.org/doc/go1.3#cgo

I belive that two libs that go-webkit2 depends on have this problem. One of them also "github.com/sqs/gojs".

If this turns out to be a big problem I am prepared to help you correcting this bug.

Thanks for the report. If you could help with a fix, that'd be great!

I found out that for me using go 1.3.1 solves most of the problems.

I've tried to use this lib on OS X and Arch Linux. On OS X I don't think I was able to fully satisfy the dependencies, but on Arch Linux I was able to. I tried on 1.2.2 1.3 1.3.1 and 1.3.3 and I keep getting more or less the same errors (there have been a few variations but I'm pretty sure they share the same root cause that's causing others similar problems).

Hmm, to make it easier to debug we should first make it not use my gotk3 fork anymore and just use te upstream. They have incorporated my patches and might have fixed this issue. Do you have time to try that?

Hi, tried to get this lib, got:

I am working on fixing this. In my unpushed branch I am now using conformal/gotk3 instead of my sqs/gotk3 fork. Still getting these errors but am working on them.

$ go build -i -tags gtk_3_10 ./webkit2
# github.com/sourcegraph/go-webkit2/webkit2
webkit2/webview.go:134: cannot convert _Cfunc_webkit_javascript_result_get_global_context(jsResult) (type C.JSGlobalContextRef) to type gojs.RawContext
webkit2/webview.go:135: cannot convert _Cfunc_webkit_javascript_result_get_value(jsResult) (type C.JSValueRef) to type gojs.RawValue

[sqs]

OK, can folks please try this now?

# be sure to update to the latest
$ go get -u -tags gtk_3_10 github.com/sourcegraph/go-webkit2/...
$ go test -tags gtk_3_10 github.com/sourcegraph/go-webkit2/webkit2
$ echo document.title | webkit-eval-js https://google.com /dev/stdin

It's working for me on Ubuntu 14.04 as of 5aa1136.

[paultag]

I've been able to build on Go 1.6; since this issue calls it 'new', this might be worth closing!
