Hello:
I am trying to build libpcap for QNX 4.25, and am experiencing
the following error:
Unable to open 'ifaddrs.h'

Is the getifaddrs() you're using part of QNX4, or is it
from some add-on library, e.g. taking the eCos implementation
and porting it to QNX4?
getifaddrs() is not part of QNX4. There is no connection whatsoever.
It is utilized in the libpcap file, 'fad-getad.c'.

Here is the relevant output, from config.log:

That's only a warning? Is there a way to force cc on QNX4 to *fail* if
some symbol isn't found? If

What autoconf wants is to have an attempt to compile and link

system that doesn't have that symbol in the libraries being

the sense in which the linker needs to fail in
Unfortunately, it'll turn *all* warnings into errors; the
only warnings I want turned into errors are the warnings for
undefined references, as there might be other warnings that
are harmless *and* difficult if not impossible to eliminate
in a configure script.
