I read about the platform that boost supports on the boost homepage. However, I do not know if it supports HP-UX.
Supported compilers and platforms. The library should build and work with a reasonably compliant compiler. The library was successfully built and tested on the following platforms:
Windows XP, Windows Vista, Windows 7. MSVC 8.0 SP1, MSVC 9.0 and newer. Linux. GCC 4.5 and newer. Older versions may work too, but it was not tested. Linux. Intel C++ 13.1.0.146 Build 20130121. Linux. Clang 3.2.
Does that mean it supports HP-UX?
