2016-06-21pcap: Add support to "new" Npcap native mode without setting PATHYang Luo1-0/+1
Npcap decided not to add "C:\Windows\System32\Npcap" to system PATH in the installation any more (starting from Npcap 0.07 r14). So this patch needs to be applied, otherwise Wireshark will not find Packet.dll (the error message will only say wpcap.dll is missing, but actually is Packet.dll missing).

The "-Wwrite-strings" flag produces nuisance warnings. These warnings are not useful, they're impossible to fix in a sane way and therefore are being handled with casts of static strings to (char *).

2014-07-03Include "capture-pcap-util.h" even if we don't have libpcap.Guy Harris1-1/+2
The routines to get libpcap version information just say "no pcap here" if we don't have it, so they're called regardless of whether we were compiled with it.

2014-07-03Regularize the help output of programs.Guy Harris1-18/+8
Only print to the standard output, and only give the version information, if a "print help" command-line option is specified. Otherwise, leave out the version information, and print to the standard error. Leave out the copyright information; it's extra cruft, and http://www.gnu.org/prep/standards/html_node/_002d_002dhelp.html doesn't say anything about it (and bash, at least, doesn't print it).
