Additional info:
Comment 1 Menanteau Guy 2016-05-13 16:26:42 UTC 
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 !

Comment 3 Than Ngo 2016-05-13 19:22:53 UTC 
it looks good for me. I will prefer to use ::gecode_boost::long_long_type for casting
