It seems to me that still some files are missing, such as "pcap.h". wenji > > ----- Original Message ----- > From: Urs Beyerle <[log in to unmask]> > Date: Wednesday, September 19, 2007 4:09 pm > Subject: Re: tcptrace compiling on Scientific Linux 5.0 X86_64 > To: [log in to unmask] > Cc: 'Connie Sieh' <[log in to unmask]>, [log in to unmask] > > > > Wenji Wu wrote: > > >> What pcap is it looking for?
