Hi, I just got my new intel core duo laptop. So I downloaded the new cygwin (including everything) but couldn't get the numarray or numpy modules installed correctly. I always got the following error. Can some one help? Many thanks!

You don't need cygwin to install NumPy. I use the mingw compiler to compile windows binaries. This error looks like a problem with the platform-dependent code, but it's showing up in an odd place. I'm not sure what the issue is. -Travis

Looks almost like a mix of mingw and cygwin. The two aren't compatible, so I wonder if the python you have was compiled with cygwin or with vc. If the latter, mingw is the proper compiler to use. Chuck
