# Build with QSC Launcher

Use the Qualcomm Software Center (QSC) Launcher to download, compile, and flash the QIR SDK.

<Warning>
  **Warning**

  It's not recommended to rebuild the QIR SDK, as the build process is complex for non-professionals. Build the QIR SDK ONLY if you understand the process and have the following needs:

  * Build an image for the device which doesn't have a prebuilt image, for example, the Qualcomm<sup>®</sup> IQ-8 Evaluation Kit. For details, see [Supported platforms](./qir-sdk-overview#supported-platforms).
  * Add new features to the QIR SDK.
  * Change the content of the target image.
  * Fix bugs in the QIR SDK.
  * Optimize the performance of the QIR SDK.
  * Change the version of certain components.
</Warning>

**Prerequisites**

* Ensure that you have installed the QSC Launcher by following the steps in [Install QSC Launcher](https://docs.qualcomm.com/doc/80-70029-254/topic/build_from_source_qsc_gui_intro.html#install-qsc-launcher) from the `Qualcomm Linux Build Guide`.
* The QSC Launcher requires Docker. Install Docker on the host computer if you haven't done so.

<Note>
  **Note**

  * QSC Launcher doesn't support WSL. Switch to the QSC-CLI ([Build with QSC-CLI](https://docs.qualcomm.com/doc/80-70029-265/topic/qsc_cli.html?product=895724676033554725\&facet=Intelligent_Robotics_Product.SDK.2.0\&version=1.8#using-qsc-cli-3-1)) if you're using WSL.
  * It's not recommended to build the QIR SDK with QSC Launcher or QSC-CLI in the Mac UTM environment. Using this method may require multiple manual retries upon errors.
</Note>

## **Download the software**

To use the QSC Launcher for downloading Qualcomm Linux based QIR SDK distributions, perform the following steps according to [Build with QSC Launcher: Download the software](https://docs.qualcomm.com/doc/80-70029-254/topic/build_from_source_qsc_gui_intro.html#download-the-software) from the `Qualcomm Linux Build Guide`.

1. Open and sign in to the QSC Launcher desktop application.
2. On the **Specify Environment** page, select the appropriate values for **Category**, **Chipset**, **Host Operating System**, **Target Operating System**, and then select **Next**.
3. In the **Select Resources** window, do the following:
   1. In the **Base Workspace Path** text box, specify a directory path where you want to download the software.
   2. Select the **Software Product**.
   3. Select the **Distribution** and the **Release Tag**. The following tables list the mapping between available software products and release tags, as well as the mapping between distributions and access levels.

      **Software product and release tag**
