The root cause is that the configure test for using gid_t or int to getgrouplist() fails. The logic is that if compiling a small test program fails, lirc uses int, otherwise it uses gid_t. This problem is most likely about the test program compilation failing for some other reason. Please scan config.log fior gid_t and see if/how that compilation fails.

[Alec Leamas]

Also, please check the discussion in [#318] which more or less looks like a duplicate.

I think you're right about the similarity ... I am not knowledgable enough to craft a patch to modify the behavior. Is this something you feel is unrelated to your source? I think the gcc package with which Arch ships will trigger this every time.

Here is the complete config.log: https://gist.github.com/graysky2/a203bbccd74d002d9a7d542091487192

[Alec Leamas]

think you're right about the similarity ..

Yes, looking at the logs it's exactly the same problem

Is this something you feel is unrelated to your source?

Yes. This is Arch using an inconsistent set of CFLAGS when compiling lirc. If you cannot resolve this by yourself it is a bug in the downstream packaging which should be filed in the Arch bugtracker (with a reference to [#318]).

I'm inclined to close this bug as a duplicate of #318.

[John A.]

Can you please review this forum post: https://bbs.archlinux.org/viewtopic.php?pid=1770498#p1770498

[Alec Leamas]

Well, at a glance it looks like lirc builds on Arch using a patch, and I guess that should solve the immediate problem. The patch is described as "upstreamable" so let's see if Lukas submits it; if so, I will certainly review it. For now, everybody should be happy and this upstream bug could be closed, right?

[John A.]

I think you're good to close unelss you want that patched attached to this ticket. I am happy to submit it if loqs doesn't want to/is too busy.

[John A.]

@Alec - Since it's 100% related to this ticket, please view the attached patch by loqs.

[Alec Leamas]

Sorry for long delay. That patch basically disables the test. While it might work on Arch it is not a general solution so it's not acceptable. Sorry also for that.

Since this is a downstream issue I'm closing the bug. Please push the issue in the mailing list if you still have problems with this.
