The problem is linked to boost package and gcc6 Referencing to https://gcc.gnu.org/gcc-6/porting_to.html, I see in chapter "Narrowing conversions": The C++11 standard does not allow "narrowing conversions" inside braced initialization lists. Just for test, I tried attached patch on gecode and it built successfully. http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=3380819 But I am not sure this patch is correct as the "rounding_mode_struct" is an union. This must be challenged ! Created attachment 1157217 [details]
patch for try
it looks good for me. I will prefer to use ::gecode_boost::long_long_type for casting it's fixed in gecode-4.4.0-8 gecode-4.4.0-9.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-4bddd248ef gecode-4.4.0-9.fc24 has been pushed to the Fedora 24 testing repository.
