Created attachment 381732 [details] Build Log When attempting to build certain -5.9999 live Qt ebuilds (for instance, qtwidgets-5.9999), one gets a build failure during src_configure stating: -process: invalid command-line switch This flag is included in qt5-build.eclass, with the comment "generate only a top-level Makefile". However, upstream has removed this flag from some (but not all!) of their configure scripts (for instance, the configure script in git://gitorious.org/qt/qt5.git still has the flag, but the configure script in git://gitorious.org/qt/qtbase.git does not). I believe that we can simply remove the flag from qt5-build.eclass and these packages will build fine, although src_configure will take (possibly significantly) longer to complete. We could also remove the flag from qt5-build.eclass, and then explicitly add it in each ebuild which supports the flag. I am willing to write a patch for this if I can get an idea of how we'd like to solve the issue.
Thanks, fixed in git. https://git.overlays.gentoo.org/gitweb/?p=proj/qt.git;a=commitdiff;h=c0aabf0dbb701c5bc469c9425c7ce2b242c50cef
