Replacing packagegroups by hand-picked componentsΒΆ

By default PELUX include components from Qt Auto using the packagegroups feature. This chapter describes how to replace these default Qt Auto components with hand-picked components in a new image.

The following packagegroups from Qt Auto are included in the PELUX image.

  • packagegroup-b2qt-automotive-addons
  • nativesdk-packagegroup-b2qt-automotive-qt5-toolchain-host
  • packagegroup-b2qt-automotive-qt5-toolchain-target

These packagegroups add several Qt Auto add-ons (includes neptune-ui among others) and packages that are used when building SDK for host and target machines.

In a typical project, the users of PELUX will build their own image. To do that add the file meta-pelux/<image-recipe-path>/<image-name>.bb and update it according to what packagegroups are intended to be included in the new image.

If all of the Qt Auto components defined in above packagegroups are needed in the new image then simply include the following line in the new image-recipe.

DESCRIPTION = "New PELUX image with QtAuto frontend"

require layers/b2qt/recipes-core/images/core-image-pelux-qtauto-neptune.bb

If the new image want to omit all of the Qt Auto components in the above mentioned packagegroups and add some other component <other-component>, then it can simply inherit from core-image-pelux in it's image-recipe and append <other-component> to the image.

DESCRIPTION = "New PELUX image without QtAuto frontend"

inherit core-image-pelux

IMAGE_INSTALL_append = " <other-component> "

If only packagegroups that are used in building Qt Auto host and target SDK are needed, then update the image-recipe as follows.

DESCRIPTION = "New PELUX image with QtAuto frontend"

inherit core-image-pelux-qtauto

If only neptune-ui and other add-ons in packagegroup-b2qt-automotive-addons packagegroup are needed, then update the image-recipe as follows.

DESCRIPTION = "New PELUX image with QtAuto frontend"

require layers/b2qt/recipes-core/images/core-image-pelux-qtauto-neptune.bb

TOOLCHAIN_HOST_TASK_remove = " nativesdk-packagegroup-b2qt-automotive-qt5-toolchain-host "
TOOLCHAIN_TARGET_TASK_remove = " packagegroup-b2qt-automotive-qt5-toolchain-target "
