Hi, in the process of building lyx for what will become Fedora 23 (rawhide at the moment) there a planned rebuild of all C++ packages in order to get the new ABI (no more cow strings)
Fedora 22 that is scheduled to be release this month has the old ABI while the next version (rawhide) supports the new ABI that does not suffers of the problems that Georg had to chase recently. Further details here: https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html While testing what packages failed with the new ABI one of the cases is LyX (2.1.3), the first builder to fail was the x86_64 one and this is why this message refers to it: https://kojipkgs.fedoraproject.org//work/tasks/1267/9651267/build.log The failures start at the begin, so there is no need to go down to find the culprit. Any idea about what is wrong here? Regards, -- José Abílio
