| > HP-UX does not support the CLOCK_MONOTONIC state. I'm sorry but CPython requires a monotonic clock since CPython 3.5. According to https://bugreports.qt.io/browse/QTBUG-22301 HP-UX < 11.3 and Solaris 9 don't support monotonic clock. It seems like gethrtime() is the right function to be used on HP-UX. https://docstore.mik.ua/manuals/hp-ux/en/B2355-60130/gethrtime.3C.html "gethrtime() is measured from an unspecified starting point and is not subject to time server and administrator changes" src: http://nadeausoftware.com/articles/2012/04/c_c_tip_how_measure_elapsed_real_time_benchmarking#gethrtimenbsp |

| I'm quite sure that once I wrote a patch using gethrtime() for Solaris, but then I saw that it's the same clock than clock_gettime(CLOCK_MONOTONIC), so I removed gethrtime() to simplify the code. See also my PEP 418, which mentions gethrtime() by the way: https://www.python.org/dev/peps/pep-0418/#solaris-gethrtime |

| I submitted a pull request for a possible fix for this issue but haven't received any feedback yet. Is there any additional information needed from me? |

| I'd love to have this fix backported to 3.5 and 3.6. It seems trivial to do, and I'd be happy to do it myself. |

| Can someone please give the list of failing tests of the Python master branch on HP-UX? |

| I am having trouble getting things build still. The problem is that the build is using a naked "ld" to link, and it is picking 32-bit mode by default in my 64-bit acc build. (Itanium) IMO the problem is configure.ac:2467 which should look more like the gcc section. I can produce a patch, and perhaps you can walk me though the submission process. |

| @David Haney: Can you please give the list of tests which fail on HP-UX? I would like to have an idea of the status of the HP-UX support. |

| I have applied the patch to 3.6.6 from the source tarball and I was able to proceed with the compilation. I would take the failed tests as blocker. Try to solve them later. Can this be closed? |
