Cannot get sample working under Go 1.6.x?

[myitcv]

Apologies if I'm missing something blindingly obvious here, but I cannot get the command line example working under Go 1.6.x

Everything works fine under Go 1.5.3, but under Go 1.6.2 I see:

$ go env

Happy to continue playing under Go 1.5.3 for now but any help much appreciated.

yes, unfortunately, gopy isn't Go-1.6 (>=1.6, actually) compliant.
you could run it with Go >=1.6 if you were to export GODEBUG="cgocheck=0" (that's not something to be done in production, though) as documented here:
https://golang.org/cmd/cgo/#hdr-Passing_pointers

I have been working off and on on rewriting some of the generated code to be compliant with the "new" cgo rules. the WIP code is there: https://github.com/go-python/gopy/tree/bind-seq
(but it's lacking a great deal of features wrt the master branch.)

I'll carve up time to get back to this during July-August.

Sorry about this.

Thanks @sbinet, appreciate the quick response

Might just be worth tweaking the README in the meantime?

[sbinet]

Right. Will do when in front of a real keyboard :)

Any plan to add support for more recent Go versions? Thanks!
