[Winpcap-users] error while building winpcap

The sources of WinPcap 4.0.2 do not compile that smoothly with VS2005/2008. 
In case you want to compile WinPcap with VS2005/2008, I suggest you to try 
the newest build available here:


Modifying the sources of WinPcap 4.0.2 to make it compile under VS2005/2008 
should not be too difficult, mainly a matter of tweaking some #define and 
#include directives here and there, but using that source package should be 
much more straightforward.

Out of curiosity, which kind of modification were you trying to apply on the 
winpcap sources?

Have a nice day
