MacroLibExtDescriptionA platform specific library extension that is generatedbased on project property values.Using macrosYou can use a macro in a project property or an environment setting using the $(macro)syntax. For example the Object File Name property has a default value of$(IntDir)/$(InputName)$(OBJ).To enable debugging of builds you should use the Build Information... dialog that ison the context menu of the project explorer. This dialog will give a full list of the macrosthat are specified for the project node selected together with the macro expandedproperty values.56 Chapter 4 Project management
5Building projectsCrossStudio provides a facility to build projects in various configurations.Build configurations and their usesConfigurations are typically used to differentiate debug builds from release builds.For example, debug builds will have different compiler options to a release buid: adebug build will set the options so that the project can be debugged easily, whereas arelease build will enable optimization to reduce program size or increase its speed.Configurations have other uses; for example, you can use configurations to producevariants of software such as a library for for several different hardware variants.Configurations inherit properties from other configurations. This provides a singlepoint of change for definitions that are common to configurations. A particularproperty can be overridden in a particular configuration to provide configurationspecificsettings.When a solution is created two configurations are generated, Debug and Release,and you can create additional configurations using Build > Build Configurations.Before you build, ensure that the appropriate configuration is set using Project > SetActive Build Configuration or alternatively the configuration box in the build toolbar. You should also ensure that the appropriate build properties are set in theproperties window.
