Created attachment 438792 [details] emerge --info output Hello, Both versions of kde-apps/cantor:5 fail to build for me recently, giving up an error around the 21% mark. "error: static assertion failed: Signal and slot arguments are not compatible." My emerge --info output and a build log are both attached for your expert review. Ordinarily, I would file a bug and go on with life and perhaps unmerge the package or mask the offending version(s) if they got in my way or Portage's way too much. In this case, kde-apps/kdeedu-meta depends on kde-apps/cantor and I do not want to unmerge kde-apps/kdeedu-meta. However, since kde-apps/cantor has already been unmerged here and does not build, I am unable to depclean and therefore stuck in a Catch 22 as I would like to proceed with a depclean. While waiting on a resolution, would epatch_user be a viable approach to working around the runtime dependency within the kde-apps/kdeedu-meta-16.04.1 ebuild? #RDEPEND="$(add_kdeapps_dep cantor)" Alternatively, would you suggest a local overlay with a copy of kde-apps/kdeedu-meta-16.04.1, omitting the '$(add_kdeapps_dep cantor)' line? Which stopgap would be the Gentoo way? While waiting on your advice I will proceed with a local overlay. Please advise at your convenience. Kind Regards, -Chicago

This looks like it's fixed upstream in 16.04.2. Until we move that to the tree, you could try the patch from upstream (all KDE ebuilds support user patches via the eclass): https://quickgit.kde.org/?p=cantor.git&a=commit&h=683418b3663ddc588c44063cc11abb20970e8e08
Thanks, 16.04.2 in tree now.
Current stable version of cantor (15.12.3-r1) is not compilable with now stabilized version of qt (5.6.1) because of this bug! So this bug should be considered a Blocker until either the commit is applied to cantor 15.12 or 16.04 is stabilized.

Fixed in https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=b462f7a5e612e49fa906a71c53d90d94f8df303a.
