Hi, Has anyone built Boost using Sun Studio 11 on Solaris 8? I tried to build with the boost source 1.33.1 and it was complaining about assertions ../link.cc or something like that. Then I saw a post which talked about BOOST_NO_INCLASS_MEMBER_INITIALIZATION. So I changed the file boost/config/compiler/sunpro_cc.hpp as follows //# if (__SUNPRO_CC < 0x570) # define BOOST_NO_TEMPLATE_TEMPLATES // see http://lists.boost.org/MailArchives/boost/msg47184.php // and http://lists.boost.org/MailArchives/boost/msg47220.php # define BOOST_NO_INCLASS_MEMBER_INITIALIZATION # define BOOST_NO_SFINAE # define BOOST_NO_ARRAY_TYPE_SPECIALIZATIONS # define BOOST_NO_IS_ABSTRACT //# endif I commented out the code where it was checking for compiler version less than 5.7. I was able to compile the code (atleast the ones I needed - date_time and serialization). Now when I try to use the built libraries with my test code, I get the following errors related to has_facet and use_facet. "/opt/idev3/dbapatla/NativeSTL/boostlibs/include/boost-1_33_1/boost/date_time/gregorian/gregorian_io.hpp", line 45: Error: Could not find a match for std::has_facet<std::Facet>(std::locale) needed in boost::gregorian::operator<<<char, std::char_traits<char>>(std::ostream &, const boost::gregorian::date&).

Has anyone come across these errors? thanks, Deepak
