bbappend usage
|
Monsees, Steven C (US)
Hello:
If I am building an image “image-ABC”, and it is composed of a number recipes, and for some of these recipes I may NOT want to install their final components within my image…
Which is the best place to modify the build with bbappend ?
Would I modify a recipe’s do_install (do_install_append-recipe_xyz) ?, or would I modify the image recipe (do_install_append-image_ABC) I am leaning this way to avoid cases where the component recipes might have bbappends in place already ?
Looking for the proper Yocto way…
Thanks, Steve

Is the approach where you remove the recipes from the image an option? Is there a reason why you want to build the recipes that you do not want to appear in your image?

The super yoctoish way would be to alter the packaging of the recipe to your needs.

Let's assume recipe-a consists of the files foo bar and it would package both files into recipe-a pkg. In the actual image you only install packages into a file system, so if you don't want bar to be installed into your final image, it'd be best to package bar into a separate package. PACKAGES_BEFORE_PN = "${PN}-bar" FILES:${PN}-bar = "bar" in this case the recipe would produce recipe-a (containing just foo) recipe-a-bar (containing just bar) You could install now (via IMAGE_INSTALL in your image recipe) just add recipe-a and only foo would be put into the final image. While a potential other image (IMAGE_INSTALL += "recipe-a-bar recipe-a") would contain both. But if you'd go down that road you have to make sure that runtime dependencies between the packages are met (using REDEPENDS:* statements), as otherwise it could turn into very hard to debug issues. So I would propose to **not** do that via bbappends, but forks of the recipes you want to repackage. Another option (as likely mentioned already) is to use rem_stuff() { rm ${IMAGE_ROOTFS}/<file you want to delete> } ROOTFS_POSTPROCESS_COMMAND += "rem_stuff;" in your image recipe

No, you got it wromg... I have a buildable image which has all the components necessary, I want to remove some overhead installed by some components that I will not be within my running application...

I am looking to selectively remove portions of 1or 2 components I will not be using from my running image

There is no one-size-fits-all answer to this. It helps if you provide specifics: what components and what portions of them and why. Alex
