Today I got https://github.com/landley/toybox/pull/97.patch and went "wait, shouldn't that have broken on my Ubuntu 16.04 test?" and dug into it and... ubuntu 16.04 isn't enabling getrandom() either, because http://man7.org/linux/man-pages/man2/getrandom.2.html lies about sys/random.h being a thing (you need to use linux/random.h) because https://lwn.net/Articles/711013/ and... This is not ripe. I'm leaning towards ripping it back _out_ again and waiting a few more years. That said, the syscall is there even in ubuntu 14.04 (4.4 kernel, syscall introduced in 3.17). The other option is wrapping the syscall myself in portability.h and saying that the libc support is too broken for words because glibc's stopped viably leading anything. Rob P.S. I tried to upgrade to a system that could run the android NDK x86-64 binaries (rather than illegal instruction segfaulting in the startup code because x86-64 has i386/i486/i586/i686 versions now but doesn't name them in a way that makes it remotely obvious anymore), but as with the last time I bought something from system76 what I thought was a netbook turns out to need wheels and a handle to be considered "portable". So that's still not part of my regular testing environment quite yet simply because I never have it _with_ me... _______________________________________________ Toybox mailing list Toybox@lists.landley.net http://lists.landley.net/listinfo.cgi/toybox-landley.net
