Hi Boosters,
 
I have been trying to build Boost 1.64.0 with Oracle Developer Studio 12.6 on Oracle Solaris 11.3 x86_64.
 
There are two errors encountered during the build.  They are:
 
1. Problem with Boost.Optional with this error messages:
"libs/log/src/named_scope.cpp", line 118: Error: Use of overloaded binary operator '=' is ambiguous.
"./boost/optional/optional.hpp", line 900: Note: Viable candidate 'boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>& boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>::operator=<boost::log::v2_mt_posix::attributes::named_scope_list&>(boost::log::v2_mt_posix::attributes::named_scope_list&)'.
"./boost/optional/optional.hpp", line 962: Note: Viable candidate 'boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>& boost::optional<boost::log::v2_mt_posix::attributes::named_scope_list>::operator=<boost::log::v2_mt_posix::attributes::named_scope_list&>(boost::log::v2_mt_posix::attributes::named_scope_list&)'.
 
2. Problem with Boost.Python with this error message:
"libs/python/src/numpy/dtype.cpp", line 61: Error: NPY_FLOAT16 is not defined.
 
Note that these two errors are the cause of 9 Boost shared libraries to not be generated.
 
I would appreciate it very much if someone could give me some pointers on how to resolve the above issues.
 
Kind regards,
Leo
