Searching I've found this info : boostorg/endian#45 (comment) :

The use of BOOST_ENDIAN and BOOST_BYTE_ORDER is deprecated. Please include <boost/predef/other/endian.h> and use BOOST_ENDIAN_BYTE instead

I've then substituted in ./include/breep/network/detail/impl/utils.tcc this line

#include <boost/detail/endian.hpp>

with :

//#include <boost/detail/endian.hpp>
#include <boost/predef/other/endian.h>


raphy@raohy:~/Breep/include$ grep --recursive "BOOST_*_ENDIAN" *
raphy@raohy:~/Breep/include$ grep --recursive "BOOST_BYTE_ORDER" *

But I get this error:
