If cross-compiling nmap against an external libpcap, the configure will always fail with no way around it: checking pcap.h usability... yes checking pcap.h presence... yes checking for pcap.h... yes checking for pcap_datalink in -lpcap... yes checking if libpcap version is recent enough... configure: error: cannot run test program while cross compiling See `config.log' for more details. Same thing happens in the ncat/ subdir which isn't surprising as both seem to use the same libpcap configure code. If people are cross-compiling, then let's just assume their system doesn't suck. If it does, then it'll fail for other reasons anyways, so ...
Thanks, I applied this in r13795 to /nmap-exp/dev/nmap. Is this the only barrier to cross-compiling you encountered? For anyone not sure what this is about, the problem was that the configure script checks the libpcap version by compiling a little program and running it (AC_TRY_RUN macro). You can't do that when cross-compiling, so Mike filled in the third argument of AC_TRY_RUN, which is the default value to use when cross-compiling.
