Problem with gnumex or cygwin/mingw setup install ?

[jérôme Lefèvre <jlefevre at mls dot nc>]

Hi,

I'm newbies in the world of cygwin et Cie.
I want build mex file within matlab (Version 5.2, OS : win2k).
Code are C or Fortran. I test borland 5.5 compiler to build dll and it 
work fine with yprime.c and my C source code.

After reading article from 
http://www.mrc-cbu.cam.ac.uk/Imaging/Common/gnumex20.shtml about 
''Compiling Matlab mex files with gcc for Windows'', i try to compile 
yprime.c with gcc. Unix emulation come from Mingw and Cygwin.
I set up path (dos and matlab), environnement and build mexopts.bat from 
gnumex with mingw gcc or cygwin gcc
But, I get an precompile file yprime.o and compile fails without more 
information.
I test cygwin gcc, issue is fatal too.

I make some change in mexopts.bat, look forum, compile in Dos and after 
in bash shell, test gnumex 1.08 and 1.09 but i don't understand what is 
wrong : setting, flag, path ...?

Could you help me ?
Many thanks. Ciao.

Jerôme
