WORKDIR in a yocto recipe

When I open bitbake files (ending with .bb extension), most of the files are using the WORKDIR variable as shown below.

S = "${WORKDIR}/git"

can you please tell me where this WORKDIR is defined.

Solution

  • The default value of ${WORKDIR} is defined in bitbake variables. But you can change it in the recipe. It points toward the directory where bitbake unpacks the package

    You can get the value of ${WORKDIR} from the bitbake environment

    bitbake -e <recipe-name> | grep ^WORKDIR=

    For a specific recipe, you can get all the variables' value by getting an environment file as:

    bitbake -e recipe_name > env
