Compiling and using libpcap on Haiku

Haiku R1/beta4 and earlier versions do not support packet capture on the loopback interface. Using this version of libpcap, loopback capture works since Haiku R1/beta5. Packet timestamping and filtering always occur in userland. Wireless monitor mode is not supported. The "any" pseudo-interface is not supported. pcap_set_buffer_size(3PCAP) has no effect. pcap_setdirection(3PCAP) is not supported. pcap_inject(3PCAP) is not supported.

The statistics reported by pcap_stats(3PCAP) on Haiku are as follows:

  • ps_recv is the number of packets successfully delivered by the kernel, before libpcap applies a filter.
  • ps_drop is the number of packets rejected by the filter.
  • ps_ifdrop is the number of packets dropped by the network interface (as seen via SIOCGIFSTATS) since the capture handle became active.

AMD64 R1/beta5

  • Autoconf 2.72 works.
  • CMake 3.28.3 works.
  • GCC 13.3.0 works.
  • Clang 18.1.7 works.
  • flex 2.6.4 works.
  • bison 3.8.2 works.

The following command will install respective non-default packages:

pkgman install cmake llvm18_clang

For reference, the tests were done using a system installed from haiku-r1beta5-x86_64-anyboot.iso.
