    \title Deploying Applications to Embedded Linux Devices

    You can specify settings for deploying applications to generic Linux devices
    in the project .pro file. You can view the settings in the
    \uicontrol {Run Settings}.

    \image qtcreator-embedded-linux-deployment-overview.png "Deploy to device"

    The files to be installed are listed in the \uicontrol {Deployment} step,
    the \uicontrol {Files to deploy} field. The \uicontrol {Local File Path}
    field displays the location of the file on the development PC. The
    \uicontrol {Remote Directory} field displays the folder where the file is
    installed on the device. Text in red color indicates that the information is
    missing. Edit the qmake \l{Variables#installs} {INSTALLS variable} in the
    project \c .pro file to add the missing files.

    When you run the application, \QC copies the necessary files to the device
    and starts the application on it.

    For example, adding

    \code
      target.path = /root
      INSTALLS += target
    \endcode

    to the project .pro file will copy the binary of your project to \c /root
    on the remote device. Additional files can be deployed by adding them to
    further targets and adding those to \c INSTALLS as well.

    \section1 Deploying on Embedded Linux

    \image qtcreator-embedded-linux-deployment-details.png "Deploy to embedded Linux"

    When you run the application on the \uicontrol {Embedded Linux} device, \QC
    deploys the application as specified by the deploy steps. By default, \QC
    copies the application files to the device by using the SSH file transfer
    protocol (SFTP), as specified by the \uicontrol {Upload files via SFTP}
    step.

    If you have a lot of data to copy, select \uicontrol Details in the
    \uicontrol {Upload Files via SFTP} step, and then select the
    \uicontrol {Incremental deployment} check box. \QC takes note of the
    deployment time and only copies files that have changed since the last
    deployment. However, when you make major changes on the device, such as
    removing files from the device manually or flashing a new disk image, or
    when you use another device with the same IP address, deselect the check box
    once, to have \QC deploy all files again.

    To only create a tarball and not copy the files to the device, select
    \uicontrol {Add Deploy Step} > \uicontrol {Create tarball}. Then remove all
    other deploy steps.

    The \uicontrol {Deploy tarball via SFTP upload} step specifies that \QC
    uploads the tarball to the device and extracts it.

    The \uicontrol {Check for free disk space} step is by default the first
    deploy step. Use it to find out whether the remote file system has enough
    space left to deploy your project. Errors due to lack of disk space can
    otherwise be hard to detect.

    \note If the SFTP upload fails, make sure that the remote device has SFTP
    enabled in its SSH daemon. Some versions of Dropbear that come without SFTP
    support will crash when an SFTP upload is being attempted. This is not a bug
    in \QC.
