Morning All, So, I've followed the Getting Started guide pretty faithfully I think; specifically on Fedora 13, Gcc 4.4.5 I've used... $ cd path/to/boost_1_48_0 $ ./bootstrap.sh --prefix=path/to/installation/prefix --show-libraries $ ./b2 install --prefix=path/to/installation/prefix That all seems to have worked Ok, and I have source and libraries in the appropriate prefix. Then I come to section 6, and in particular section 6.1, which talks about library naming. My libraries don't appear to be named according to this structure. Taking, for example, Boost.Regex I have libboost_regex.a libboost_regex.so libboost_regex.so.1.48.0 with no mention of toolsets or ABI tags. Does all the naming stuff only apply if you haven't used the host's default/native toolset? Thx, - Rob.
