\title Building for Multiple Platforms
You can build applications for multiple target platforms, or using different
compilers, debuggers or Qt versions. \l{glossary-buildandrun-kit}{Kits}
define the tools, \l{glossary-device}{device} type and other settings to use.
By default, when you run the application, you
automatically build and deploy it first.
However, you can also perform each operation separately.
To check that the application code can be compiled and linked for a device,
you can build the project. The build errors and warnings are displayed in
the \uicontrol {Issues} output pane. More detailed information is displayed
in the \uicontrol {Compile Output} pane.
To build an application:
\list 1
\li Click the \uicontrol {Build and Run Kit Selector} icon (1) or select
\uicontrol Build > \uicontrol {Open Build and Run Kit Selector} to select the
build and run \l{glossary-buildandrun-kit}{kit}.
\image qtcreator-kit-selector.png "Kit selector"
\li Choose \uicontrol Build > \uicontrol {Build Project} or press
\key {Ctrl+B}.
You can also select the \uicontrol Run button (2) to also deploy and run
the application after building it.
\endlist
While the application is being built, the \uicontrol Build button (3)
changes to a \uicontrol {Cancel Build} button. To cancel the build, select
the button, press \key {Alt+Backspace}, or select \uicontrol Build >
\uicontrol {Cancel Build}. If you selected a build command and
decide you would also like to run the application, you can select the
\uicontrol Run button to schedule running the project after building is done.
For more information on the options you have, see
\l{Specifying Build Settings}.
\section1 Additional Build Commands
The \uicontrol Build menu contains additional commands for building,
rebuilding, and cleaning projects.
To build the current project in all its configurations, that
is, for all build configurations in all enabled kits, select
\uicontrol {Build Project for All Configurations}.
To build all open projects, select \uicontrol {Build All Projects}.
If building one application fails, \QC displays an error message and
continues building the other applications.
To build all open projects in all their configurations, select
\uicontrol {Build All Projects for All Configurations}.
To quickly check the compile output for changes that you made in one file or
subproject, you can use the \uicontrol Build menu commands to build a file or
subproject. The available build menu commands depend on the build system
you selected for the project: CMake, qmake, or Qbs.
Select \uicontrol {Build for Run Configuration} to
build the executable that corresponds to the selected run configuration.
You can also use the \c cm filter in the \l {Searching with the Locator}
{locator}.
To remove all build artifacts, select \uicontrol {Clean Project} or one
of its variants.
To clean the build directory and then build the project, select
\uicontrol {Rebuild Project} or one of its variants.
To build and clean projects without dependencies, select the
\uicontrol {Build Without Dependencies},
\uicontrol {Rebuild Without Dependencies}, and
\uicontrol {Clean Without Dependencies} options in the context menu in the
\uicontrol Projects view.
To run qmake or CMake to regenerate build system files, select
\uicontrol Build > \uicontrol {Run qmake} or \uicontrol {Run CMake}.
\section1 Building with CMake
\QC automatically runs CMake when you make changes to \c {CMakeLists.txt}
files. To disable this feature, select \uicontrol Tools >
\uicontrol Options > \uicontrol Kits > \uicontrol CMake >
\uicontrol {Autorun CMake}.
For more information, see \l {Setting Up CMake}.
\section1 Building with qmake
To prevent failures on incremental builds, it might make sense
to always run qmake before building, even though it means that
building will take more time. To enable this option, select \uicontrol Tools
> \uicontrol Options > \uicontrol {Build & Run} > \uicontrol qmake >
\uicontrol {Run qmake on every build}.
