Hi, "sed" stands for "stream editor". It is mainly used for filtering the text. GCC uses AWK and sed when installing. It is by default installed with Linux. I don't know whether they are part of Cygwin environment. Don't hesitate to install these packages in your environment. You would get them for free. Before installing sed, please check if it is already available to you. It may just not be included in your path. In my system, it is in /bin directory.

I have downloaded all of the necessary files to install gcc, and put them in a folder C:/gcc-3.2.2 I have made another folder called C:/gcc-objdir And then I went to that directory and typed C:/gcc-3.2.2/configure And the following error message appeared: sed: not found I have no idea what that means and therefore do not know how to successfully configure and ultimately install gcc. Any help you can offer would be very much appreciated. Thank you for your time. Kind regards, Josie Ellis
