gotype and cgo, "invalid composite literal type"

[Nathan Youngman]

Hi,

This is a case of code that builds and runs fine but gotype doesn't particularly care for:

context := C.FSEventStreamContext{info: unsafe.Pointer(es)}

$ gotype fsevents.go 
fsevents.go:208:13: invalid composite literal type invalid type

I saw one related issue about supporting cgo in cmd/vet.
https://code.google.com/p/go/issues/detail?id=4889

Personally, I'm not looking for that. I just would like to not have the error.

As cmd/stringer uses gotype under the hood, I also get this error there. The obvious workaround is to put the constants in a separate file that doesn't contain any C structs.

Nathan.

Please file a bug with the issue tracker with a minimal reproducible case and assign it to me. Thanks.

PS: The issue is that gotype doesn't know about cgo and types imported via "C". It tries to ignore respective errors as much as possible but it doesn't do a perfect job in some cases.
