Hi Rob,
I am getting few other warnings related to "portability.h".
When compiling for ARM target it throws
warning: implicit declaration of function 'getsid'
warning: implicit declaration of function 'getpgid'
I'm not finding either of those in the current toybox code?
I also compiled using the armv5l toolchain at:
http://landley.net/aboriginal/bin/cross-compiler-armv5l.tar.bz2
And it complained that gethostbyname in netcat is obsolescent (which is
a uClibc glitch about ipv6 support I think) but otherwise had no
warnings?
I built with the musl wrapper, and didn't see those warnings either.
(I'm working through several other bugs it found... possibly in musl
for some of them.)
adding the header "unistd.h" and function prototype in potability.h
for #if
defined(__GLIBC__)
section solves it for me.
We already #include unistd.h in toys.h, but portability.h is #included
before that (so it can do feature test macros if absolutely necessary,
although I try to avoid that).
Is this the right way of doing it?
It's a reasonable workaround, but I'm not reproducing this problem so I
can't say what's actually going on.
Is there somewhere I can get a toolchain that reproduces this? (Is it
from Code Sourcery perhaps?)
Rob
