hi i want to build blender 4.50 source code but i want hide the console window how i do it?

1. You must mean 2.50, not 4.50
2. You can't. The console is something present only on windows builds, and they shouldve made it hidden by now...

For 2.49 and earlier, there is a link flag for building a Windows app without the console. I don't recall what it is and am too lazy to look. I realize many people are frighted by the evil black window, but that is where your error messages end up. Rather useful at times.

In 2.50, there is an integrated interactive console 'window'. It is part of the application and not a separate window.
