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 lwip\src\include\ipv4\lwip\inet.h

error C2011: 'sockaddr_in' : 'struct' type redefinition lwip\src\include\lwip\sockets.h

This types are already defined in winsock.h

 

How can I fix this problem?

Since windows already provides the same functionality lwIP does (the socket interface), you have to ensure the socket-related headers of lwIP are not included in the same c files as one of the windsock headers. In other words, clean up your includes and you should be done.

I'm using lwIP on win32 successfully on various simulation projects.
