Hi Markus

I'm not sure what you are trying to achieve. From a distance I would say you don't Need a lwIP on a Win32 platform as Win32 delivers an IP-Stack with more or less Berkeley Sockets (WinSock2).

If your simulation project has to share some of the PowerPC code I would recommend to you to build an abstraction layer to program with. Although Winsock supply a more or less Berkeley-like socket interface, there are still some calls you have to invoke that do not fit.


Quoting address@hidden:

I'm using lwip 1.4.1 in an embedded project (PowerPC) very successful.

Now I'm trying to add lwip to the target simulation project (Win32
Visual Studio 2013). The build fails with conflicts like:

error C2011: 'in_addr' : 'struct' type redefinition
error C2011: 'sockaddr_in' : 'struct' type redefinition

This types are already defined in winsock.h

How can I fix this problem? Thanks for any hints!
