It is complaining about the pcap.h file. ./pcap.h:45:23: fatal error: pcap/pcap.h: No such file or directory Line 45 is #include And inside the pcap folder is pcap.h It is stated in the first pcap.h file. /* * For backwards compatibility. * * Note to OS vendors: do NOT get rid of this file! Many applications * expect to be able to include , and at least some of them * go through contortions in their configure scripts to try to detect * OSes that have "helpfully" moved pcap.h to without * leaving behind a file. */ This should work. Unfortunately pcaprub was last updated in 2010. Know of any other good pcap libs for ruby? -- Posted via http://www.ruby-forum.com/.
