Hi Loris!
Thanks for the info, I couldn't send a mail to the WinPcap users-list as I'm not subscribed, so I got the answer this way :-)
To make a long story short: the use of the Packet32.h file is only required for the "Interface Details" dialog implemented in gtk/capture_if_details_dlg.c (and the loader of the packet.dll in capture_wpcap_packet.c).
Although this info (e.g. interface link speed) will be helpful in certain situartions, it seems to make deep trouble to compile this.
As I don't want to force all our Win32 developers to install the Platform SDK only for this reason, I'm thinking about making it optional through a definition in config.nmake.
This way, the default would be to compile without this dialog and thus without the Platform SDK.
Regards, ULFL
