Using ACE and Qt

If i want to using ACE and Qt togethor,what shall i do to set up my development environment under windows and linux?

You speak of the "ADAPTIVE Communication Environment"?
Well, that's a library as many thousand other libraries are. You have to set the "include path" to the ACE header files for the compiler and you have to set the library path to the library for the linker.

If you use Visual Studio, KDevelop or Eclipse or anything else you always have to look at the project settings.
