[Bug 1361940] Re: patches for cgo on arm64
Got access to another machine and tested. My test was pretty basic,
using this file:
ubuntu@ms10-36-mcdivittB0:~$ cat trivialcgo.go
package main
import "C"
func main() {
}
Even with the patch in https://bugs.launchpad.net/ubuntu/+source/gccgo-
go/+bug/1361946/comments/16 this file cannot be run:
ubuntu@ms10-36-mcdivittB0:~$ go run trivialcgo.go
no buildable Go source files in /home/ubuntu
But after installing gccgo-4.9 from proposed, it can:
ubuntu@ms10-36-mcdivittB0:~$ go run trivialcgo.go
ubuntu@ms10-36-mcdivittB0:~$
(I was going to test using docker, but I can't remember which version of
docker I used before: the one in trusty-updates does not build, I think
because it depends on the patching of the standard library archive/tar
package by add-tar-xattr-support.patch that the debian packaging for
golang in trusty carries but that gccgo does not. I can probably find a
version that works if you really want).

Hello Michael, or anyone else affected, Accepted gccgo-4.9 into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gccgo-4.9/4.9.3-0ubuntu4 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .
