yes we need to disable CGO which is not yet in and therefore not part of 1.14.x release

Comment 2 Khem Raj 2020-07-09 12:49:55 UTC

patch is on ml

Comment 3 akuster 2020-08-13 08:26:48 UTC

is this the fix?

http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-devtools/go?id=192d6e9b4739bb53e513e78da5d552a3f1d931d3


and go was updated.

please close issue is resolved.

Yeah, CGO is disbaled now so that's the work around.  Hopefully in the future we can re-bale CGO for all these platforms.
