I have been using boost 1.45 on HP-UX using the acc compiler. Have used the following libs: asio, serialisation, file-system,data-time,program-options, shared_ptr spirit(classic) You need to test each library yourself. since as you have discovered boost is not officially supported on HP-UX. It appears as if HP-UX is no longer develop's/maintains their compilers.?
