Created attachment 443038 [details, diff] guvcview-2.0.3-r1.patch Suggested patch.
*** Bug 592418 has been marked as a duplicate of this bug. ***
*** Bug 592458 has been marked as a duplicate of this bug. ***
Given bug 592458, will most likely affect all guvcview versions supporting qt5.
I can confirm that the patch works with guvcview-2.0.4 and qt-5.7.0. Without the patch, guvcview-2.0.4 fails to build.
Fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=91e8cc6c3de0be2ccbf9ce282e858e5ac719bbc7
