The thing is, the breakage I describe is *really* weird. Unpack my 2019 uclibc-ng stage3 on a MIPS system, chroot in, everything works fine. But the instant you recompile ncurses inside of it, using the *same* Portage snapshot that it was built from, the Python interpreter falls over with a NULL deref in its curses module. I've debugged it down to the exact line of C code in Python, but cannot find an explanation why it fails. I've had my share of weird crap running these SGI systems, but this one takes the cake. That's why I gave up on uclibc-ng for a time until I could try kickstarting a new build from scratch using OpenADK (which still supports older pre-mips32/64r* platforms). No other choice, really, because once Python goes down, so too does emerge. Even bugged it on Python's bug tracker, but no surprise it's gone ignored: https://bugs.python.org/issue39819 In any event, yeah, I don't have a real issue with dropping it. I've noticed that some of the more recent commits to it are really just ingesting chunks of glibc and stripping out some of the macro fluff. There's actually a change in upstream glibc I've yet to test on one of my non-coherent cache platforms that uclibc-ng pulled in that probably breaks them in fun fun ways (not that that platform ever worked well from the beginning, though...). -- Joshua Kinard Gentoo/MIPS [email protected] rsa6144/5C63F4E3F5C6C943 2015-04-27 177C 1972 1FB8 F254 BAD0 3E72 5C63 F4E3 F5C6 C943 "The past tempts us, the present confuses us, the future frightens us.
