Subject: Re: [PATCH 3/5] libxl: Generate golang bindings in libxl Makefile
Date: Sat, 23 May 2020 13:00:37 -0400	[thread overview]
Message-ID: <CAEBZRScr-6Lt29tHFNgOBmZhXBW0oBB-NcoqTBi9xr5GgQaZVQ@mail.gmail.com> (raw)

> The generated golang bindings (types.gen.go and helpers.gen.go) are
> left checked in so that they can be fetched from xenbits using the
> golang tooling.  This means that they must be updated whenever

>    xenlight/Makefile which will only re-generate the files.
>
>  - Add a target in libxl/Makefile to call external idl generation
>    targets (currently only golang).
