9189	"Solaris Studio 12.3, boost::log: explicit template instantiations need ""template<>"""	Brian Vandenberg <phantall+boost@…>	Andrey Semashev	"When building libs/log/src/settings_parser.cpp with Solaris Studio 12.3, I'm getting the following errors.  FYI: I changed convert.hpp by applying the fix suggested in ticket #7513.

{{{
""./boost/fusion/sequence/convert.hpp"", line 23: Error: apply is not a member of boost::fusion::extension::convert_impl<boost::fusion::struct_tag>.

/* More errors afterward, but they appear to be repeats of existing errors */
}}}

The following change(s) will get rid of the errors:

{{{
 208: #ifdef BOOST_LOG_USE_CHAR
-209: template BOOST_LOG_SETUP_API basic_settings< char > parse_settings< char >/*...*/
+209: template<> BOOST_LOG_SETUP_API basic_settings< char > parse_settings< char >/*...*/

 211: #ifdef BOOST_LOG_USE_WCHAR_T

+212: template<> BOOST_LOG_SETUP_API basic_settings< wchar_t > parse_settings< wchar_t >/*...*/
 213: #endif
}}}
