Hi,
 
This is a resend with the suggested change on the subject line.
 
I have been trying to build Boost 1.64.0 with Oracle Developer Studio 12.6 on Oracle Solaris 11.3 x86_64 in C++14 mode.
 
There are three errors encountered during the build.  They are:
 
1. Problem with Boost.Log with this error message:
>> Assertion:  (../lnk/initializer.cc, line 1865)
while processing ./boost/log/expressions/message.hpp at line 98.
My comment:  Acknowledged by Oracle as a compiler issue.
 
2. 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&)'.
My comment:  Ambiguous boost::optional<>::operator=(), possibly a Boost configuration issue or compiler SFINAE issue.  I’m not that fluent with SFINAE to be able to figure this out.
 
3. Problem with Boost.Python with this error message:
"libs/python/src/numpy/dtype.cpp", line 61: Error: NPY_FLOAT16 is not defined.
My comment:  Possibly a Solaris package installation issue due to no support contract.  (numpy package fails to install)
 
I would appreciate it very much if someone could give me some pointers on how to resolve the above issues.
 
Kind regards,
Leo
