importing "C" is not supported by GopherJS

[Patrick Lismore]

Hi 

I am compiling a project from go to javascript and one of my files is throwing this exception.

func (e *ImportCError) Error() string {
 return e.pkgPath + `: importing "C" is not supported by GopherJS`
 }

Can someone explain a little bit more on what is happening when the above gets triggered.

thanks P

In my go file there is an import

import "C"

[Ian Lance Taylor]

import "C" is used by cgo, which is used to call between Go and C; see  https://blog.golang.org/c-go-cgo .

Apaprently GopherJS does not support C code, which is not surprising.

Hey Patrick,

Ian is right. GopherJS does not support cgo.

I've noticed that it's not actually documented anywhere, so I've filed an issue (https://github.com/gopherjs/gopherjs/issues/515) and made a PR (https://github.com/gopherjs/gopherjs/pull/516) to fix that.
