[Mingw-users] Confusion with Cygwin netinet include files

[Paul L. <sa2...@cy...>]

I've had a MinGW app running successfully for some time, but I've now 
added some sockets code to it. The sockets code includes netinet/in.h, 
among other things.

The app has both C sources, and C++ sources (previously, it was only C++):

 > cc --version
  cc (GCC) 3.4.4 (cygming special...)

 > g++ --version
  g++.exe (GCC) 3.4.5 (mingw special)

I've got the MinGW executables in my path before the Cygwin executables.

The problem is that the compiler can't pick up netinet/in.h. After some 
investigation, it turns out that cygwin has installed these headers in 
the usual place (/usr/include/netinet/), but there is no equivalent 
netinet in the MinGW directory (at /mingw/include).

Actually, 'cc' *is* finding <netinet/in.h>, presumably the Cygwin 
version, and compiles the C code Ok. g++ is just complaining that it 
can't find <netinet/in.h>. I don't know if the C code has actually 
compiled Ok, because it has to link with the compiled C++ code, and I 
can't get far.

Any idea what's going on? Can the Cygwin headers be used for MinGW? Why 
is cc picking up the cygwin headers anyway, while g++ isn't? Do I need 
to dosomething else to get sockets code running on MinGW?

Thanks -
