Over time, the compiler improved, but the libCstd ABI was set in stone. The compiler has become more capable, but the RogueWave derived STL is still configured to be non-compliant in order to maintain the ABI set when the compiler was less capable. I presume backwards compatability was considered more important than standards compliance. Here's an OpenSolaris proposal to change this (not sure of the status of Solaris 11). The RogueWave STL has become the Apache STDCXX project, If that becomes the new STL on Solaris, then Boost may be usable with the default compiler and STL configuration. However Boost + SunStudio/libCstd is likely to be non-starter as Boost requires a high level of standards compliance. Even Boost + SunStudio/STLport didn't work for quite some time. Here's a blog I used to follow as SunStudio/STLport approached usability with Boost. The first version that worked out of the box was 1.34.1. Thanks, Paul
