Re: [Java-readline-users] java readline on windows

Hi Craig,

the JavaGetline.dll in the contrib-directory is only created with cygwin, it 
should run without it. Can you reproduce your problem from a "normal" 
DOS-prompt (to be honest: I have not yet worked with XP, so I don't know if 
it still has a DOS-prompt).

It might be possible that the DLL does not run under XP (the Visual C++ 
compiler is rather old). I have not yet managed to create a working DLL with 
cygwin, it should be possible but I can't figure out how.
