Someone left a line that adds -Werror to CXXFLAGS in the CMakefile. Obviously, it errors out when you have different warnings or a different version of GCC. On today's GCC 4.6.0 (no longer pre-release!) with default options and just -O2, it doesn't build. Attached patch fixes this.

Created attachment 267349 [details, diff] patch to not add Werror to CXXFLAGS - fixed
+*clementine-0.7 (28 Mar 2011) + + 28 Mar 2011; Samuli Suominen <ssuominen@gentoo.org> +clementine-0.7.ebuild: + Version bump wrt #360845 by Agostino Sarubbo. Remove -Werror from + src/CMakeLists.txt wrt #360703 by Zeev Tarantov. The patch loosk good, you should submit it to the upstream ticketing system at googlecode. It can't be what they want... Meanwhile I've done this with oneliner sed in the ebuild
According to upsteam: "Source builds are for developers. Developers want the build to break when there are compiler warnings." (http://code.google.com/p/clementine-player/issues/detail?id=1637) So all Gentoo users are developers of Clementine and want the build to break when there are warnings. If not, Gentoo has to patch out -Werror by itself - it will not be removed. Also, GIO is apparently unstable and disabled by default and it being compiled is proof that I am not a regular user (that, of course, and me using the just released GCC 4.6.0).
