It supplies a host-side compiler and a target sysroot with the headers and libraries needed to build Qt applications. To create or install the right SDK, first match the board’s BSP, Yocto release, Qt layer revisions, image, and required Qt modules.
What a Qt 5 Yocto SDK contains
Yocto builds an SDK around a target configuration. Its toolchain runs on the developer’s host, while the sysroot represents the target environment against which applications are compiled and linked. The generated installer can be relocated after installation, but it remains specific to the build configuration that produced it. See the Yocto Project Concepts manual for how layers, target configuration, and cross-development toolchains fit together.

Qt 5 support comes from the meta-qt5 layer, which provides OpenEmbedded/Yocto recipes. Your board’s BSP layer contributes machine-specific configuration; the layer combination and release compatibility determine what can actually be built. The OpenEmbedded Layer Index entry for meta-qt5 lists meta-toolchain-qt5 as the package for building an installable Qt 5 toolchain and SDK.

Identify a compatible target before building
There is no universal command sequence or Qt Creator kit that works for every board. Before choosing a build, establish these details from the board or SoM vendor’s current documentation:

- Target: the board, SoM, SoC, and supported machine configuration.
- Software stack: BSP layer, Yocto release, and compatible revisions of the layers.
- Host: the development host architecture supported by the SDK installer.
- Qt requirements: Qt version and the modules your application needs.
- Image and workflow: the image configuration and whether developers need only a cross-toolchain or Yocto-aware tools such as
devtool.
Qt’s target-device catalog for Qt for Device Creation illustrates why exact matching matters: it lists selected hardware, Qt releases, and operating-system combinations, with support tiers. Its entries are not evidence that an unlisted board or combination is supported. Confirm the precise board, Qt and Yocto releases, BSP, and required modules with the vendor.
Build and install the SDK
Use the layer revisions and instructions supplied for your board and Yocto branch. If that stack provides meta-toolchain-qt5, building it is the documented route to an installable Qt 5 SDK; the exact layer setup and build environment remain vendor- and release-dependent.
- Set up the vendor’s Yocto build: check out the documented release and compatible BSP and Qt layers, and configure the target machine and image as directed.
- Check Qt module configuration: the
meta-qt5project notes that some modules requirePACKAGECONFIGoptions to be enabled for theqtbasebuild. Include only the modules your target and application require. - Build the toolchain package: where supported by the layer stack, run
bitbake meta-toolchain-qt5from the configured build environment. - Install the generated SDK: run the resulting
.shinstaller on the development host and follow its prompts. The installed environment setup script exposes the toolchain and sysroot to build tools.
These steps describe the general route, not a substitute for the board vendor’s branch-specific setup. For example, the TQ Group development-host workflow uses bitbake meta-toolchain-qt5, then configures Qt Creator around its own installed SDK. That example is specific to its Qt 5.13.2 and Yocto Zeus-based setup; its paths and version values should not be copied to another target.

Choose a standard SDK or an extensible SDK
Use a standard SDK when developers need the compiler, target headers, libraries, and sysroot to build applications for a prepared image. An extensible SDK (eSDK) includes additional Yocto build-system functionality, including devtool, for workflows that modify or extend recipes and SDK sysroots.
| Choice | Best fit | How it is supplied |
|---|---|---|
| Standard SDK | Application development against the target toolchain and sysroot, without requiring Yocto’s internal build workflow. | Generated as an installable SDK for the selected build configuration. |
| Extensible SDK | Teams that need Yocto-aware development, including devtool and sysroot operations. |
Can be set up directly in the Yocto build environment or distributed as a standalone archive. |
Yocto’s Extensible SDK manual documents its contents and setup options. Choose based on how the application team manages dependencies and whether it needs to make Yocto-level changes; an eSDK is not simply a different Qt version.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Configure Qt Creator to use the matching SDK
Qt Creator must use the SDK generated for the same target and Qt configuration as the application. Configure the environment setup script, compiler, sysroot, and qmake or Qt version from that SDK or from the board vendor’s instructions. A kit assembled from a different board’s paths or binaries may compile incorrectly or fail to link against the target libraries.

- Includes 12 pcs cables of various lengths and styles (10cm,20cm, 30cm, 50cm. SH1.0 connector and breadboard Jumper and Female Jumper)
- Each Qwiic Cable's wires have been color coded to red, black, blue and yellow
- Uses this cable to quickly hook up sparkfun and development boards with sensors, LCDs, relays and more.
- The female and male dupont connector also suitable for raspberry pi and Arduino development boards
The TQ walkthrough shows a board-specific example that sources environment-setup-aarch64-poky-linux and selects a target sysroot and Qt version. Treat that filename and the example’s Qt Creator values as specific to the documented setup, not standard names guaranteed by every SDK.

Account for module and architecture constraints
Qt module availability depends on the recipes, configuration, and target. The meta-qt5 documentation flags a particular constraint for qtwebengine: some 32-bit ARM targets may require a host compiler capable of producing 32-bit code. This is not a general prerequisite for every Qt 5 SDK. Check the layer documentation and vendor configuration for the module and architecture you intend to build.
If a requested module is missing from the SDK, verify that it is available in the selected layer revisions and enabled in the build configuration, then regenerate the SDK from the appropriate image or toolchain configuration. Do not assume that adding a Qt Creator kit installs a module or changes the contents of the target sysroot.
Verify support for the exact combination
Qt’s target-device catalog distinguishes Tier 1 reference targets, Tier 2 verified targets, and Tier 3 other targets. The catalog describes differing support arrangements and testing expectations across those tiers; its entries change over time. It includes an Ezurio BD-SL-i.MX6 kit with Qt 5.15 and Yocto 3.1, while many current examples use Qt 6 with newer Yocto releases. Those entries do not establish support for every board sharing a processor family. Verify the specific hardware, BSP, Yocto release, Qt version, and modules with the vendor before committing to a configuration.
