How to install mingw manually?

Once I saw gcc version 4 at sf.net host page of mingw,I managed to download the whole package and install the new package,开发者_开发问答but it turns out a lot of mistakes(create process errorwhile run gcc and give out non-meaningful code) and Now I have to rollback to the orginal automatical installed version.

My question is: is there anyone have successfully installed the mingw(with gcc v4) manually?

I really don't know what you mean by "manually", and I don't know what "sf.net" is. If you want to install MinGW, download from http://tdragon.net/recentgcc - current latest version 4.4.1 - and run the installer. You can install multiple versions - I usually have two or more on the go at once.

If this isn't what you are asking, please clarify your question.
