[Insight-developers] Re: [Insight-users] Fixing bugs for ITK with MinGW

[Ali -]

Luis,

I am on a different machine today which, as well as mingw, has an installation of cygwin. Unfortunately cmake find the cygwin installation in the registery (cugwin bin directory is not in the path) and gives errors of type:

 "...gcc is not able to compile a simple test..."

Putting mingw in the path does not help. Is this a known issue? How is it possible to configure cmake for mingw without uninstalling cygwin?
