Joe, The yum install command did the trick. The make command worked flawlessly afterwards, so I now have a bridge executable. The yum install command gave me the impression that it downloaded a new file from the Internet, is that correct? Now I m testing the bridge program . Hans Van: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] Namens Joe Ferraro Verzonden: maandag, juli 2010 0:01 Aan: hecnet at update.uu.se Onderwerp: Re: [HECnet] Attaching to hecnet Hans, Assuming you can priv up to root, you should be able to search the `rpm` database on your system (I believe you said you are on a red-hat system). # rpm -qa |grep -i pcap If libpcap is not installed, you may be able to use a tool such as `yum` to identify the package that you need to add. For example: # yum whatprovides */libpcap.so */libpcap.a <... SNIP...> 14:libpcap-devel-0.9.4-15.el5.x86_64 : A pcap library. Repo : base Matched from: Filename : /usr/lib64/libpcap.so 14:libpcap-devel-0.9.4-15.el5.x86_64 : A pcap library. Repo : base Matched from: Filename : /usr/lib64/libpcap.a You could then, potentially, install one of the listed libs... # yum install libpcap-devel* or what have you.... Pay attention to the path... you may need to instruct the bridge code on the whereabouts of the lib... (which can, of course be determined with the fore-mentioned rpm commands)...
