In Modules/timemodule.c, py_process_time() still uses floatclock() even when HAVE_CLOCK isn’t defined. |

What is your platform? time.process_time() supports many functions: - GetProcessTimes() (Windows only) - clock_gettime(CLOCK_PROF) - clock_gettime(CLOCK_PROCESS_CPUTIME_ID) - getrusage(RUSAGE_SELF) - times() - clock() On POSIX, clock() is always tried as a fallback. Does your platform support at least one of these functions? |

I’m building against the Newlib libc, for the Wii, and it seems the issue leading to all of those functions not working is: (.text.clock+0x18): undefined reference to `_times_r' Threading is disabled, and reentrant functions as well, which could explain that. But still, when pyconfig.h doesn’t define any HAVE_ macro to get the system time, I would expect py_process_time() to return None or something instead of failing to build. |

Please attach your pyconfig.h file. |

Sorry but the Wii console is not supported. You have to maintain your fork/patch. Python 3 don't support platforms without clock(). |
