libpcap0.8 required?

Asked by Phydeaux

Hi

I have noticed that version 1.7.25~ubuntu14.04.1 of the wine-compholio package has a dependancy on libpcap0.8.

I wondered why this is? It seems odd.

Thanks

Hi,

the reason for this is that Wine now supports a Pcap -> WinPcap wrapper. It is one of the feature mentioned in the Wine release notes: https://www.winehq.org/announce/1.7.25

I have to agree that it is questionable whether you want a version build with it. Most of the libraries in Wine are loaded dynamically, so that we can make an optional dependency on it. Wine would simply print a warning when the library is not available, but this is not the case for pcap which is statically linked. We only had the choice to make it a hard dependency or disable the feature completely. Since most people have trouble compiling Wine on their own, we decided to include the feature as test in our Ubuntu builds only. However we also talked to person who is responsible for this wrapper and asked him to convert it into a dynamic loadable library. We hope to convert this to an optional dependency in the future.

PS: By default your user account does not have the necessary permissions to sniff any traffic using Pcap.
