Qbs

The Qbs build helper is a wrapper around the command line invocation of the Qbs build tool. It will abstract the calls like qbs resolve, qbs build and qbs install into Python method calls.

The helper is intended to be used in the build() and package() methods, to call Qbs commands automatically when a package is being built directly by Conan (create, install).

from conan import ConanFile
from conan.tools.qbs import Qbs, QbsDeps
class App(ConanFile):
    settings = "os", "arch", "compiler", "build_type"
    exports_sources = "*.h", "*.cpp", "*.qbs",
    requires = "hello/0.1"
    options = {"shared": [True, False], "fPIC": [True, False]}
    default_options = {"shared": False, "fPIC": True}
    def generate(self):
        deps = QbsDeps(self)
        deps.generate()
    def build(self):
        qbs = Qbs(self)
        qbs.resolve()
        qbs.build()
    def package(self):
        qbs = Qbs(self)
        qbs.install()

Reference

class Qbs(conanfile, project_file=None)

Qbs helper to use together with the QbsDeps feature. This class provides helper methods that wraps calls to the Qbs tool.

• Parameters:

  • conanfile – The current recipe object. Always use self.

  • project_file – The name to the main project file. If not set, Qbs will try to autodetect the project file.

• add_configuration(name, values)

  Adds a build configuration for the multi-configuration build. This Qbs feature is rarely needed since each conan package can contain only one configuration, however might be useful when creating multiple versions of the same product that should be put in the same Conan package.

  • Parameters:

    • name – the name of the configuration. This corresponds to the config parameter of qbs resolve, qbs build and qbs install commands.

    • values – the dict containing Qbs properties and their values for this configuration.

• resolve(parallel=True)

  Wraps the qbs resolve call. If QbsDeps generator is used, this will also set the necessary properites of the Qbs “conan” module provider automatically adding dependencies to the project. :param parallel: Whether to use multi-threaded resolving. Defaults to True.

• build(products=None)

  Wraps the qbs build call.

  • Parameters:

    products – The list of product names to build. If not set, builds all products that have builtByDefault set to true. This parameter corresponds to the --products option of the qbs build command.

  The resolve() method should be called before calling this method.

• build_all()

  Wraps the qbs build --all-products call. This method builds all products, even if their builtByDefault property is false. The resolve() method should be called before calling this method.

• install()

  Wraps the qbs install call. Perfoms the installation of files marked as installable in the Qbs project. The build() or build_all() methods should be called before calling this method.
