I got

[ 235s] CMakeFiles/engine-headless.dir///System/SpringApp.cpp.o:SpringApp.cpp:function SpringApp::SpringApp(int, char*): error: undefined reference to 'google::SetUsageMessage(std::string const&)' [ 235s] CMakeFiles/engine-headless.dir///System/SpringApp.cpp.o:SpringApp.cpp:function SpringApp::SpringApp(int, char): error: undefined reference to 'google::SetVersionString(std::string const&)' [ 235s] CMakeFiles/engine-headless.dir///System/SpringApp.cpp.o:SpringApp.cpp:function SpringApp::SpringApp(int, char): error: undefined reference to 'google::ParseCommandLineFlags(int, char***, bool)' [ 235s] CMakeFiles/engine-headless.dir///System/SpringApp.cpp.o:SpringApp.cpp:function __static_initialization_and_destruction_0(int, int) [clone .constprop.160]: error: undefined reference to 'google::FlagRegisterer::FlagRegisterer

as a consequence I submitted https://build.opensuse.org/request/show/570204 to remove springlobby from Factory. This still needs a lot of love to actually become playable.

Upstreamed your boost patch: https://github.com/spring/spring/pull/362

I have tried to fix the current build errors. So far, I got:

• boost::signals was removed (replaced by boost::signals2, part of libboost_headers-devel). Upstream handled this well in advance, we just need to change the "BuildRequires: ..." line
• There is a problem in rts/Rendering/GL/myGL.cpp, where I had to "pickpocket" some upstream commits.

Now, there is

"lto1: internal compiler error: in get_odr_type, at ipa-devirt.c:2098"

and I don't know how to proceed.
