Re: [lwip-users] lwip 1.4.1 and win32: conflicts with 'in_addr', 'sockaddr_in', ...

Hi Simon

Thank you for your answer. I will try to clean up my includes.

Is there an example project for lwip 1.4.1 and win32? The one from the contrib 
package I didn't get running.

Thanks a lot
Markus

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.
