The reason that I got geos to compile previously was that I was using the line:<br>#if defined(__MINGW32__) && !defined(DLL_EXPORT)<br><br>and the condition wasn't being met therefore there was no multiple definition problem.<br><br>I understand these __......__ things are macros. Having tried Mark's patch:<br><br>#if !defined(__MINGW32__) || defined(__MINGW32__) && !defined(DLL_EXPORT) || !defined(__CYGWIN__) || defined(__CYGWIN__) && !defined(DLL_EXPORT)<br><br>, it doesn't work, neither does:<br><br>#if !defined(__MINGW32__) || defined(__MINGW32__) &&
!defined(DLL_EXPORT) || !defined(__CYGWIN32__) || defined(__CYGWIN32__)
&& !defined(DLL_EXPORT)<br><br>So it doesn't appear that the __CYGWIN__ macro is being defined. Can anyone point me in the direction of what's going on here? I know now it's not essential for me to build at all, but it might be for other systems & I want to learn and help out the community if I can.<br><br>Regards<br><br>Stephen (noob if you hadn't guessed!)<br></div><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"><br><div style="font-family: arial,helvetica,sans-serif; font-size: 10pt;"><font size="2" face="Tahoma"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk><br><b><span style="font-weight: bold;">To:</span></b> GEOS Development List <geos-devel@lists.osgeo.org><br><b><span style="font-weight: bold;">Sent:</span></b> Tuesday, 4 November, 2008 21:56:19<br><b><span style="font-weight: bold;">Subject:</span></b> Re: [geos-devel] Fw:

It looks as if Cygwin doesn't define _WIN32 unless you specifically compile with <br>-mwin32 which is why it's still not working. I've reworked my original patch to use the<br>__CYGWIN__ define instead, which I've attached to this email for you to<br>try. Please apply against a geos-3.0.2 tarball and let us know how you<br>get
