Adding libraries to our image using package groups in yocto project

 Hello All,

In my previous article we have seen that, how we can add the different libraries to our image using yocto project.

previous article here: https://learnyoctowithme.blogspot.com/2022/06/adding-libraries-pciutilsusbutils-and.html

In this article we are going to see how we can add multiple libraries(packages) at the same time using the concept of package groups in yocto project

Before proceeding to this, you need to  be familiar with my previous articles , as it contains the necessary steps to create the build environment for qemux86-64 and steps to create our own layer.

pre-requisite: https://www.blogger.com/blog/posts/8695339245532547417?tab=rj


Adding libraries to our image using package groups in yocto project:

step 1: switch to our own layer (meta-mylayer/recipes-kernel)

$ cd poky/meta-mylayer/recipes-kernel/

step 2: inside recipes-kernel directory, create a folder called packagegroups

$ mkdir -p packagegroups

step 3: switch to packagegroups directory

$ cd packagegroups

step 4: inside packagegroups directory, create a file called "my-custom-packagegroup_0.1.bb" file

$ touch my-custom-packagegroup_0.1.bb

step 5: Edit the file my-custom-packagegroup_0.1.bb as

$ vi my-custom-packagegroup_0.1.bb


step 6: save and exit the file

step 7: now add this my-custom-packagegroup file to our image configuration file as

$ vi ../../../build_x86/conf/local.conf


step 8: Now compile the image as

$ bitbake core-image-minimal


step 9: now run the image as

$ runqemu nographic

step 10: now test our packages are available in our image as following

$ lspci



$ lsusb


$ lsblk


$ lshw



That's it now we have successfully integrated different libraries to our image using package groups.
