gdb does not connect to IPv6 only remote target

[Seki, Tsutomu]

I'm trying to connect to remote target that has only IPv6(Link-Local) address;
> $ getent hosts hogehoge.local
> fe80::XXXX:XXff:feXX:XXXX hogehoge.local

but it fails after few seconds delay;
> (gdb) target remote hogehoge.local:2159
> hogehoge.local:2159: Connection timed out.

- release version: 5-2015-q4-major
- host machine: Ubuntu 14.04.3

Thanks in advance!

Hi Andre,

Thank you for your advice.

I'm feeling afraid to submit the patch to upstream, because I only have tested;
 - to build on ubuntu targeting arm-none-eabi,
 - and to run it on ubuntu,
while gdb supports a lot of hosts and targets, and cross-compilation hosts.
I'm not so sure if it works properly on different hosts, or for different targets.

I think I should prove the patch works at least for this package before submitting to upstream.
Could anyone help me to try or review the patch?

Regards,
sekiriki

Hi Seki,

You dont need to be afraid of submitting the patch upstream. As long as you clearly state what your initial issue was, which seems quite clear to me and say that you have only tested it on "x" and "y" thats fine. The maintainers upstream will review the patch and help with the testing too if needed.

Maybe this link will be of some help: http://www.gnu.org/software/gdb/contribute/

Cheers,
