How to create a custom bitbake recipe from a public repository

  1. Open a terminal and navigate to the directory where you want to store the recipe. We assume that the application to add is called DesiredApp(adjust the name accordingly).
  2. Create a new file with the .bb extension using your preferred text editor. For this example, we'll call the file "".
  3. Start the recipe by defining the metadata. Here's an example:
SUMMARY = "Recipe for DesiredApp"
DESCRIPTION = "Compiles DesiredApp from a public GitHub repository"
LIC_FILES_CHKSUM = "file://LICENSE;md5=4d92cd373abda3937c2bc47fbc49d690"
SECTION = "examples"

SRC_URI = "git://;protocol=https"
SRCREV = "8fdea40ca783de02d3bc5833a97d6113e772495f"
S = "${WORKDIR}/git"

inherit cmake
  1. In the metadata, the SRC_URI parameter defines the URL of the GitHub repository to be cloned. The SRCREV parameter specifies which branch or commit to check out, it generally is recommended to use a SHA hash here to point to a particular commit in history. The S parameter specifies the location where the source code will be stored after cloning.
  2. The inherit parameter tells BitBake which class to inherit from for building the application. In this example, we're using the cmake class, which will automatically generate the Makefiles and build the application using the CMake build system, in other cases, you may need to use inherit makefile or inherit meson, depending on the application.
  3. Save and close the file.
  4. Add the recipe to your BitBake build environment by including it in your local.conf file. To do this, open local.conf and add the following line:
BBFILES += "/path/to/your/recipe/"
8. Save and close **local.conf**.
9. Build the recipe using the **bitbake** command:

bitbake desiredapp

This will download the source code from the GitHub repository, build the application using CMake, and create a package containing the compiled binaries. The package will be stored in the **tmp/deploy/** directory of your BitBake build environment.
