First off, I did try the method listed in the other Cygwin Pennmush forum, but no luck :( - I receive this (huge) list of errors (for bsd.c):

Basically, I'm asking: Do I get rid of socket.h, or winsock.h? And what do I do about the strange parse errors?

By the way, here's an output with no winsock:

You haven't said what version you are compiling, but I got it to compile and run after some minor tweaking. :)

This example uses 1.7.4 p15 which seems to be the latest stable version right now.

First step, unzip the file, configure, update the config.h file ...


tar xvzf pennmush-1.7.4p15.tar.gz
cd pennmush
./Configure -d
make update


Now, edit config.h and comment out two lines:


/* #define HAS_SETLOCALE / **/
/* #define HAS_IPV6 / **/


Now, in the "src" directory, edit mysocket.c and comment out two lines:


// #include <resolv.h>
// extern int h_errno;


Should work now - try a "make".


make
make install

Ahh! I see what I did wrong - I did apply the changes to the files, like you said, the first go-around. However, I chose to use the options "win32-gcc" < I guess that with Cygwin, it's sort of disputable whether I'm running Win32-GCC . . . anyway, it worked with ./Config -d (default configuration), so, it must have been that - I guess. Maybe looking for the Win32 version of gcc???

Yes, when using Cygwin, I tend to *not* tell it that it is a WIN32 compile. I know it is on Windows, but the Cygwin environment is really a "Unix" environment.

That is why I suggest that people using Cygwin just use the Unix source, not source modified for Windows.
