Hum, that's definitely a signal that ntl has been compiled with -std=c++11 and eclib doesn't. Which is strange because I put code in configure to make sure it would pick up the c++11 bit myself. I probably didn't take into account a corner case. On the other hand I think eclib should just switch to c++11 by default.
Nevertheless there is some strangeness happening there. Can you post the log for ntl please? Francois On 10/03/17 09:01, Darij Grinberg wrote: > Hi Isuru, > > thank you.
