there is still a similar issue at unstable amd64 tinderbox image 17.1_no-multilib-20200425-101740 (see bug 710508)

Upstream issue https://github.com/ossec/ossec-hids/issues/1871 filed.

[Comment 9 Ralph Seichter 2020-05-20 19:00:25 UTC]

Upstream has confirmed this issue as a bug on their end. According to the comments, they are currently testing fixes.

[Comment 10 Ralph Seichter 2020-05-24 17:39:49 UTC]

Upstream has made changes to address the issue. I have opened the linked pull request which modifies ebuild version 3.6.0 to include a patch which combines these changes.

[Comment 11 pagorman 2020-05-30 03:49:00 UTC]

Regarding the specific patch referenced above (direct link): 

https://github.com/gentoo/gentoo/blob/fb18da88a281137148ff8eb5260ef8160016d870/net-analyzer/ossec-hids/files/gcc-fno-common-3.6.0.patch

without patching? I receive the same build errors using GCC10.

removing '/src' from each patched file's path was required.

When patched via '/etc/portage/patches' method, the existing ebuild compiles with no new warnings since upgrading to GCC10.

Still roadtesting, but no new issues found.

> removing '/src' from each patched file's path was required.
The patch works fine as it is, if applied correctly, as is done in the ebuild contained in my linked pull request. Somebody with the proper Git permissions just needs to merge the PR.

[Comment 13 Ralph Seichter 2020-06-04 17:36:54 UTC]

The pull request has been merged with https://github.com/gentoo/gentoo/commit/cc3444458dded272e5f8313f7ec2762af2f11f6c , please test.

[Comment 14 Ralph Seichter 2020-08-02 21:46:14 UTC]

As there have been no comments made after I asked for tests being conducted two months ago, I close this issue now.
