Several problems in the use of QT qmake: Pro, PRI, PRF, prl file config usage

Any entry in the Config row is also a scope. For example, you write this:


CONFIG + + warn_on
You will get a scope called "warn_on". This will make it easy to modify the configuration in your project without losing all of the customizations that might be required under certain conditions. Because you may put your own values in the Config line, this will provide you with a very powerful configuration tool for your makefile. Like what:


CONFIG + + qt warn_on Debug
Debug {
TARGET = Myappdebug
}
Release {
TARGET = MyApp
}
In the above code, two scopes are created, and they depend on what is set in the Config row. In this example, debug is in the config row, so the target variable is set to Myappdebug. If release is in the Config row, the target variable will be set to MyApp.

When you write an application, you usually just change it. Pro can


. PRI is project include file, which is used to place a more generic configuration and variable here. If you are working on a project and need to compile multiple applications and libraries, you can modify the. pri file.


The. prf file, typically used in a large compilation system. For example, if you want to design a QT cell phone yourself, you may need a different identity to specify the compilation features when compiling different modules. Then some new definition identifiers can be used in. prf.
For example, if you want to use config+= Nokia, this Nokia tag is not in Qt, you write a nokia.prf can let qmake identify.
