That's right, that's what i've done.
And It's not the first time that i've post this question.
Each time I've found link option to lib\gcc_dll\msw but after compiling, the folder name is gcc_msw.
If I link to, i got errors.
I don't understand anything about thoses parameters, I made test without understanding what I do....
If you prefer delete this post, it doesn't matter I still looking for solution with searching tools.
Thanks for your reply
