Created attachment 1128149 [details] Patch to upgrade to 0.9.3 and fix the FTBFS The trigger of this FTBFS is a clash between a package-local class "mutex" and class "std::mutex", caused by "using namespace std;" within the package. One approach to address this issue would be to remove "using namespace std;" and to make "std::" explict. Another one is to rename the local "class mutex". The patch (against Fedora's git master) in the attachment implements the latter, because it's less intrusive and better suited as a temporary work-around. It renames "class mutex" to "class seq24_mutex." for seg24-0.9.3 (final). I have not managed to apply this approach to seg24-0.9.3-r131.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
Taking. I am going to apply my proposal above.
