cmd/cue: cue get go doesn't support uintptr type

[vikstrous2]

What version of CUE are you using (cue version)?

cue version v0.4.0 linux/amd64

Does this issue reproduce with the latest release?

yes, on master

What did you do?

go mod init tmp.com
go get istio.io/api/networking/v1alpha3
cue get go istio.io/api/networking/v1alpha3
cue eval ./...

What did you expect to see?

success

What did you see instead?

_#field: reference "uintptr" not found:
    ./cue.mod/gen/github.com/gogo/protobuf/proto/pointer_unsafe_go_gen.cue:11:10
package "reflect" not found:
    ./cue.mod/gen/github.com/gogo/protobuf/proto/properties_go_gen.cue:7:8

I'm seeing this too, with the v1beta version (cue get go istio.io/api/networking/v1beta1).
I get the same error message from cue eval.

I just had this with 0.4.2 also.

Hi 👋– I have this "issue" with github.com/cilium/cilium/pkg/k8s/apis/cilium.io/v2 too and I found this issue here. I use cue 0.4.2 and used:

go get github.com/cilium/cilium/pkg/k8s/apis/cilium.io/v2
cue get go github.com/cilium/cilium/pkg/k8s/apis/cilium.io/v2

to validate instances of #CiliumNetworkPolicy

It seems like this is a simple omission of the uintptr type from the Go import logic.
Here's a simple reproducer:

exec cue get go example.com/m
exec cue vet example.com/m

-- cue.mod/module.cue --
module: "example.com/c"
-- go.mod --
module example.com/m

go 1.18
-- m.go --
package m

type Foo struct {
	X uintptr
}

This fails currently:

> exec cue get go example.com/m
> exec cue vet example.com/m
[stderr]
#Foo.X: reference "uintptr" not found:
    ./cue.mod/gen/example.com/m/m_go_gen.cue:7:10
[exit status 1]
