Ping seems to work as-is in the new NDK version, so yay. >> Except support for 32 bit's being dropped at some point and I dunno the >> schedule >> of that in the ndk... hmmm.

I should link those from the toybox web page somewhere... Ah, under android roadmap makes sense. I see the plan to move to compiler-rt: Are you familiar with Rich Pennington's http://ellcc.org ? He got a toolchain with no gnu components working a few years ago, including compiler-rt. (He works down the hall from me at my current contract, we keep meaning to sit down some evening and work out an update of ellcc that would let me use his toolchain in my https://github.com/landley/mkroot project but we've both been too busy so far...) > but, no, 32-bit isn't going anywhere any time soon. we *are* insisting > that folks have a 64-bit version of any 32-bit app so that at some > point it'll be possible to have a 64-bit-only device, but i assume > even that will only be another step in the slow decline of 32-bit. 32 bit's alive and well in the embedded space, and x32 remains interesting on 64 bit systems, but there's only 20 years until y2038... (Embedded's weird: I'm told there are more nommu processors than with-mmu processors in the world, which is about like saying there are more bacterial cells than non-bacterial cells in the world. Embedded Linux is about like the "insects" layer of the ecosystem, which is still flipping enormous.) > (and remember that the NDK effectively has to worry about ~5-year old > devices, so even if you weren't allowed to ship a 32-bit P device I'm all for it.

Good to know. My personal experience has been... different. Wikipedia[citation needed] says the Nexus 5 was introduced October 31, 2013, my blog says I got mine for christmas 2014, and it got its last update October 2016. I.E. my phone was "supported" for just under 2 years after I bought it, it's been a zombie for a couple years already, and 5 years from the hardware's launch date isn't 'till halloween. *shrug* I'm still using it (three screen replacements and a new battery later). It's remotely exploitable at least 3 different ways I know of (https://www.krackattacks.com/ https://www.theverge.com/2017/9/12/16294904/bluetooth-hack-exploit-android-linux-blueborne https://youtu.be/TDk2RId8LFo ), still running Marshmallow, and half the time I want to use the camera I have to reboot the phone first. But there's no guarantee T-mobile would support anything I move _to_ any longer than it did this one, is there? Still, it's nice Google's better about this than the phone companies. (I keep meaning to put Oreo on it. I unlocked the bootloader last year when I disabled the "Google App" in the because online insructions said that stopped flaky earbud connections from popping up Google Voice every 30 seconds, and the resulting boot loop required a factory reset to undo, and as long as the thing was wiped _anyway_... only took 3 days. But I haven't tried to put an experimental build on it because I use it as a phone; my netbook runs a stock ubuntu LTS for the same reason. And every other device I've gotten to experiment with, I _haven't_ managed to get the bootloader unlocked yet. Mostly due to lack of deadline pressure I expect...)
