Build failure handle different libpcapso filename #253

Closed Wojtek242 closed 1 year ago

Wojtek242 commented 1 year ago

The build.rs script is updated to no longer crash if it cannot find libpcap to query for its version. It will instead assume that the user is by default using the newest API version. For older API versions the user should consult the README.

So for example, if the user has a different libpcap.so file name the following might happen:

  1. libpcap is at its newest version which means that the default assumed by build.rs is good enough.
  2. libpcap is not at its newest which means the build will fail. The user should then consult the pcap README.
  3. In the README the user finds that they can set LIBPCAP_LIBDIR and LIBPCAP_VER. The LIBPCAP_LIBDIR will fail since build.rs still assumes the libpcap.so name, but as a final fallback the user can set LIBPCAP_VER.

So in short, the original problem is solved. Either libpcap is at its newest version or the user has to set LIBPCAP_VER.
