Ethereal-dev: [Ethereal-dev] [PATCH] Detect WinPcap from Unix-style build on Cygwin
This patch allows the Unix build process to find libpcap as -lwpcap, the name it
takes when in the form of WinPcap. This lets one build on Cygwin with a simple
--with-pcap=/cygdrive/c/ethereal-win32-libs/wpdpack, assuming one has set up the
libraries directory for a VC++ build.
I tested on Windows 2000 with a very recent Cygwin and the WinPcap developer
pack that win32-setup.sh downloads. I also tested on Fedora Core 1. I lack
access to an AIX(?) machine on which to test the -lcfg -lodm logic, however.
