Description Petros 2015-05-09 15:34:18 UTC

cmake doesn't cooperate with GCC-5.1 and LTO. I am using git binutils (9999) and I want to recompile my KF5 with it, but cmake is getting in the way. So I am pretty much stuck here with a non-working cmake.

Reproducible: Always

Steps to Reproduce:
1. emerge cmake
2.
3.
Actual Results:  
/var/tmp/portage/dev-util/cmake-3.2.2/temp/ccary0lH.ltrans14.ltrans.o:<artificial>:function cmGlobalGenerator::WriteSummary(cmTarget*): error: undefined reference to 'Json::Value::Value(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'


I am trying to recompile everything with json in it's name with no success. For example dev-libs/jsoncpp-0.10.2 rants about cmake and stuff when linking. In another report more about this.

It's probably an ABI issue - try rebuilding with USE="internal-jsoncpp".

Yep cmake emerged fine. =dev-libs/jsoncpp-0.10.2 too.

Let's find out what about KF5.
