Is something wrong with libpcap-0.4-29.i386.rpm? I wanted to use the "sting" packet-loss measurement tool from http://www.cs.washington.edu/homes/savage/sting/ This tool uses libpcap, and should work on Linux (the author said it does). Anyway, using /usr/lib/libpcap.a it didn't work (from the little debugging I did, it appears as if pcap_next does not timeout correctly, and just gets stuck). When I compiled libpcap-0.4 (which is also available in sting's tar) myself (easy - just did configure and make) and used the resulting library, sting worked perfectly. Could it be that something is wrong in the way libpcap-0.4 is compiled, or something? I know from (bad) experience that static libraries compiled in previous versions of gcc (e.g., on Redhat 6.2) no longer work correctly on Redhat 7, giving seemingly random and hard-to-detect lockups and errors. Using objdump -x on this library says that it was compiled on Aug 12 - that is way before Redhat 7 was released, so maybe you just forgot to recompile it for the new gcc?
Linux uses a different libpcap than you are expecting. See details at bugzilla #6773 et al.
