Using Apple’s SimplePing on iPhone OS

If you try out of the box to compile Apple’s “SimplePing” code sample on the iPhone OS, you’ll wind up with a lot of errors as some files don’t exist in those SDKs. Specifically, you need these files (you need more than just these files to compile, obviously, but these are the ones that aren’t included):

/usr/include/netinet/ip.h
/usr/include/netinet/in_systm.h
/usr/include/netinet/ip_icmp.h
/usr/include/netinet/ip_var.h

So here’s a quick Bash script that links the relevant files to your iPhone OS and iPhone Simulator SDKs:

for path in /Developer/Platforms/iPhone*/Developer/SDKs/*; do
    for file in /usr/include/netinet/ip.h \
                /usr/include/netinet/in_systm.h \
                /usr/include/netinet/ip_icmp.h \
                /usr/include/netinet/ip_var.h; do
        if [ ! -f "${path}${file}" ]; then
            sudo ln "${file}" "${path}${file}"
        fi;
    done;
done

I’ve spoken to an Apple engineer and confirmed that this is the best way to do it, as well as filed a bug, which I encourage you to do as well if this annoys you.
