Product Item

A product typically represents the result of a build process. It specifies a set of input and output files and a way to transform the former into the latter. For example, the following product sets up a very simple C++ application:

Product {
    name: "helloworld"
    type: "application"
    files: "main.cpp"
    Depends { name: "cpp" }

The type property specifies what will be built (an executable). The files property specifies the input files (one C++ source file), and the Depends item pulls in the logic from the cpp module about how to do the necessary transformations. For some often-used types of products, Qbs pre-defines special derived items that save users some typing. These are:

  • Application
  • CppApplication
  • DynamicLibrary
  • StaticLibrary

Therefore, the above example could also be written like this:

CppApplication {
    name: "helloworld"
    files: "main.cpp"

Any property prop attached to this item is available in sub-items as product.prop, as well as in modules that are loaded from this product.

builtByDefaultbooltrueIf false, the product will only be built if this is explicitly requested, either by listing the product name as an argument to --products or by giving the build command the --all-products option.
conditionbooltrueIf false, the product will not be built.
namestringempty stringThe name of the product. Used to identify the product in a Depends item, for example. The value of this property must be a simple JavaScript expression that does not depend on module properties or values that are non-local to this product.
CppApplication {
    name: "hello" + "world"                     // valid
CppApplication {
    name: "app_for_" + qbs.targetOS.join("_")   // invalid

To change the name of your product's target artifact, modify Product.targetName instead.

profilesstringList[project.profile]The profiles for which the product should be built. For each profile listed here, one instance of the product will be built according to the properties set in the respective profile. This property is only relevant for projects that require products being built for different architectures. Otherwise it can be left at its default value.
typestringListempty listThe file tags matching the product's target artifacts.
targetNamestringname with illegal file name characters replaced by underscoresThe base file name of the product's target artifacts.
destinationDirectorystringproduct.buildDirectoryThe directory where the target artifacts will be located. If a relative path is given, the base directory will be project.buildDirectory.
filesstringListempty listA list of source files. Syntactic sugar to save a Group item for simple products.
excludeFilesstringListempty listA list of source files not to include. Useful with wildcards. For more information, see Group Item.
consoleApplicationboollinker-dependentIf true, a console application is generated. If false, a GUI application is generated. Only takes effect on Windows. This property also influences the default application type on Apple platforms. If true, an application bundle is generated. If false, a normal executable is generated.
qbsSearchPathsstringListproject.qbsSearchPathsSee the documentation of the Project Item property of the same name. The value set here will be merged with the one inherited from the project.
versionstringundefinedThe version number of the product. Used in shared library filenames and generated Info.plist files in Apple application and framework bundles, for example.

The following properties are automatically set by Qbs and cannot be changed by the user:

buildDirectorypathThe build directory for this product. This is the directory where generated files are placed.
profilestringThe profile for building this particular instance of the product. Derived automatically from the profiles property.
sourceDirectorypathThe source directory for this product. This is the directory of the file where this product is defined.
