Hi, I've got a lexer created with flex (cygwin). Normally I compile it to an .exe file. For the newest project I need a lexer to use in a bigger C# program running on Windows XP. Of course I can execute a file using System.Diagnostics.Process. But it is not the best solution for me as I want that program to run on several machines. How can I create a dll under cygwin having the source code of the lexer? Thanks in advance... Szpilona
