\title Setting Up a Qbs Project
To use Qbs to build a project, you must create a .qbs file for the project.
You can use \QC to create a C or C++ project that is built with Qbs.
For more information about Qbs, see
the \l{http://doc.qt.io/qbs/index.html}{Qbs Manual}.
The application is built using the default Qbs profile that is associated
with the build and run kit. \QC automatically creates a Qbs profile for each
kit. You can edit the build profiles by adding new keys and values.
\section1 Building Qbs
If you build \QC yourself from the \QC Git repository, you also need to
fetch the Qbs submodule to get Qbs support:
\list 1
\li Fetch the Qbs submodule in your \QC git checkout with
\c {git submodule update --init}.
\li Run qmake on \QC and build \QC again.
\endlist
\section1 Building Applications with Qbs
To build your application with Qbs:
\list 1
\li Select \uicontrol File > \uicontrol {New File or Project} > \uicontrol {Plain C
Project (Qbs Build)} or \uicontrol {Plain C++ Project (Qbs Build)} >
\uicontrol Choose, and follow the instructions of the wizard to create a
Qbs project.
\image creator-qbs-project.png
\li Edit the .qbs file for you project. Usually, you must add the
\c Depends item for a Qt application. For examples, see the
\c {examples} directory in the qbs repository.
\li Select \uicontrol Projects to specify \uicontrol {Build Settings} for the
project.
\li Select \uicontrol {Build Steps} > \uicontrol Details to specify build steps:
\image creator-qbs-build-app.png
\list 1
\li In the \uicontrol {Build variant} field, select \uicontrol Debug to
include debug symbols in the build for debugging the
application and \uicontrol Release to create the final
installation file.
\li In the \uicontrol {Parallel jobs} field, specify the number of
parallel jobs to use for building.
\li Select the \uicontrol {Enable QML debugging} check box to debug
Qt Quick application projects.
\note Debugging requires opening a socket at a well-known
port, which presents a security risk. Anyone on the Internet
could connect to the application that you are debugging and
execute any JavaScript functions. Therefore, you must make
sure that the port is properly protected by a firewall.
\li In the \uicontrol Properties field, specify the properties to pass
to the project. Use colons (:) to separate keys from values.
For more information, see
\l{http://doc.qt.io/qbs/language-introduction.html}
{Modules} in the Qbs Manual.
\li In the \uicontrol Flags field:
\list
\li Select \uicontrol {Dry run} to test building without
executing commands or making permanent
changes to the build graph.
\li Select \uicontrol {Keep going} to continue building when
errors occur, if possible.
\li Select \uicontrol {Show command lines} to print actual command lines
to the compile output pane instead of high-level descriptions.
\li Select \uicontrol {Install} to copy artifacts to their install location
after building them. This option is enabled by default.
\li Select \uicontrol {Clean install root} to remove the contents of
the install root directory before the build starts.
\endlist
\endlist
The \uicontrol {Equivalent command line} field displays the build command
that is constructed based on the selected options.
\li Select \uicontrol {Clean Steps} > \uicontrol Details to specify flags for the
cleaning step.
\image creator-qbs-build-clean.png
\list
\li Select \uicontrol {Clean all artifacts} to remove all build
artifacts.
\li Select \uicontrol {Dry run} to test cleaning without executing
commands or making permanent changes to the build graph.
\li Select \uicontrol {Keep going} to continue cleaning when errors
occur, if possible.
\endlist
The \uicontrol {Equivalent command line} field displays the clean command
that is constructed based on the selected options.
\li Select \uicontrol Build > \uicontrol {Build Project} to build the application.
\li Click the
\inlineimage qtcreator-run.png
(\uicontrol Run) button to deploy and run the application.
\endlist
\section1 Editing Build Profiles
\image qtcreator-options-qbs.png
You can modify a build profile that is associated with a build and run kit
by editing the values of the keys generated by \QC and by adding new values:
\list 1
\li Select \uicontrol Tools > \uicontrol Options > \uicontrol Qbs.
\li In the \uicontrol Kit field, select a build and run kit.
\li Select \uicontrol Edit to edit the profile associated with the kit.
\li Select \uicontrol Add to add keys and values to the profile or to
modify existing values.
\li In the \uicontrol Key column, spefify the key to add or modify as:
\c <module_name>.<property_name>.
\li In the \uicontrol Value column, specify a value as a JSON literal.
\li Click \uicontrol OK.
\endlist
The values that you have modified are displayed in red in the
\uicontrol {Profile properties} field.
For a list of available keys and values, see the
\l{http://doc.qt.io/qbs/list-of-modules.html}{List of Modules} in the
Qbs Manual.
