I am trying to get sockets to work in Windows using the MinGW environment. The following program is from Microsoft. No matter what I do, I cannot get MyEclipseIDE to include the winsock2.h include file. It does not complain until it gets to the definition of sockaddr_in which is defined in the include file.

1) Is there a way to get a listing created that shows the results after the preprocessor step so I can tell what is happening?

2) How do I link against a library (.a file) as opposed to a dll? MinGW has the libws2_32.a file which hopefully includes the socket routines, but I cannot figure out how to get MyEclipseIDE to use them. I can use the ws2_s2.dll file in the visualStudio directory, but I would rather stick to free things.

Thanks for the help,
Jim

And yes, I did put the mingw\include in my path

in the compiler’s include path
