Provisioning a remote package server

Setting up an HTTP remote package server and pointing your target clients at it is easier than you might think. The client-side server address configuration varies between package managers. We will configure opkg manually on Raspberry Pi 4.

Let’s start with the package server:

1. First, navigate one level above the directory where you cloned Yocto.
2. Next, set up your BitBake work environment:

   $ source poky/oe-init-build-env build-rpi
   

3. This sets a bunch of environment variables and puts you back in the build-rpi directory.
4. Build the curl package:

   $ bitbake curl
   

5. Populate the package index:

   $ bitbake package-index
   

6. Locate the package installer files:

   $ ls tmp-glibc/deploy/ipk
   

7. There should be three directories, named cortexa72, all, and raspberrypi4_64, in ipk. The architecture directory is cortexa72 while the machine directory is raspberrypi4_64...
