Subject: cygwin c++ linking help

Hi,

This isn't directly pertaining to ruby under cygwin, because I can 
successfully compile ruby under cygwin. I am attempting to compile 
wxruby under cygwin and I haven't had that much luck. All of my files 
compile but when the object files are linked together they always error 
out with a bunch of "undefined resource" errors. I was wondering if 
anyone with more experience in this area could point me in a direction , 
like my library file isn't being found, i am missing a library file, I 
should check my library file for certain method signatures, etc...

here is some of the output i get...any pointers would be of great help. 
Thanks,

Zach
