Qbs 2.3.0 released

The Qbs build tool version 2.3.0 is available.

What’s new

As hinted at last time, the main feature in this release is the use of the new Language Protocol Server for “go to definition” in certain contexts and auto-completion.

Language Protocol Server

We have added a Language Protocol Server to Qbs which provides IDE-agnostic tooling (https://microsoft.github.io/language-server-protocol). On top of it, we added the “go to definition” feature to QtCreator - it is now possible to open source files from *.qbs files by simply pressing F2. We have also added support for autocompletion of the module properties:



We have added a possibility to export products to CMake via the new Exporter.cmake module. This allows to use libraries built with Qbs directly with CMake projects without the need to use an intermediate representation in form of the Exporter.pkgconfig.

We deprecated the “fallback” module provider in favor of the qbspkgconfig provider. In Qbs, module providers generate missing modules during the project configuration (“resolve”) stage. Historically, we had only Qt and “fallback” module providers and there was no way to control which providers are run until we introduced “named” module providers in Qbs 1.21. At the same time, we’ve added the qbspkgconfig provider that reads .pc files directly, avoiding expensive invocations of the pkg-config tool. Since then, we had two almost identical providers that work on top of .pc files. However, the problem with the “fallback” provider is that it works differently from other providers as well as suffers performance issues and has the same bugs as the pkg-config tool. Thus, we decided to deprecate the “fallback” provider in Qbs 2.3.0 and remove it in Qbs 2.4.0. For details on how to use the qbspkgconfig provider, see the provider page in the documentation. Also, please report any bugs in the qbspkgconfig to the bug tracker.

We have added a new Tutorial section in the documentaion to make it easier to grasp core concepts and make users familiar with best practices. Also, we added a new example on how to use Exporter modules.

If a project needs to be re-resolved, we now print the reason. Also, we rewrote the wildards handling to track changes more accurately.

C/C++ Support

We fixed an issue with complex project structure that lead to a non-linear algorithm during traversing of the dependencies. Now, private dependencies (dependencies of static libraries) of products are not traversed more than once anymore (QBS-1714).


  • Module properties are now accessible for groups in modules (QBS-1770).
  • The qbspkgconfig.mergeDependencies property was removed. This feature only existed because of performance limitations which were fixed in Qbs 2.1.0.
  • ModuleProviders now support the allowedValues property of the PropertyOptions item (QBS-1748).
