# Import dependencies from the SDK simulation

Source: [https://docs.qualcomm.com/doc/80-41102-1/topic/import-dependencies-from-the-sdk-simulation.html](https://docs.qualcomm.com/doc/80-41102-1/topic/import-dependencies-from-the-sdk-simulation.html)

Use the [SDK Simulation's](https://docs.qualcomm.com/doc/80-PF458-9/topic/simulation-telsdk.html) user guide to download and
            compile the SDK Simulation project.

TelAF Simulation depends on the artifacts compiled from the SDK Simulation project, for
            example the 'rootfs' installation directory generated by the SDK Simulation project.

Note: The following only shows the CLO main repository of the SDK simulation. Replace the
                    `SDK-SIMULATION-TAG` in each TelAF cadence release note
            with the specific **Commit-ID** or **TAG**.

Some examples from the SDK Simulation User Guide:

**Get and build the SDK Simulation project**

$ git clone https://git.codelinaro.org/clo/le/platform/vendor/qcom-opensource/snaptel-sdk.git -b telsdk.lnx.2.0.r11-rel telux
    $ cd telux/
    $ git checkout -b mhead <SDK-SIMULATION-TAG>
     
    # default output directory is `pwd`/rootfs
    $ ./build_sim.sh setup
    $ ./build_sim.sh all
     
    # get the absolute path of 'rootfs'
    $ realpath `pwd`/rootfsCopy to clipboard

After the above steps, the absolute path of the generated 'rootfs' is logged in the
            console output. Pass the path when building the TelAF 'simulation'
            target.

    cd <telaf_root_dir>
    make simulac IMPORT_SDK_SIMULATION=y sdk_rootfs=<path/to/your/generated/rootfs>Copy to clipboard
