OpenSUSE Build service howto

Small openSUSE ac100 howto

Some general things

openSUSE ARM board rootfs images are made by KIWI image system (JeOS = Just Enough Operating System) https://en.opensuse.org/Portal:KIWI

openSUSE use OBS (Open Build Service) system for continous integration of packages and images. https://en.opensuse.org/OBS OBS look very similar to git but also include build functions, requests and etc.

openSUSE OBS lives here https://build.opensuse.org/

OBS have console tool osc

To include some programm or files into future rootfs image you need to create obs package for it.

Create custom JeOS package

• JeOS custom package must contain _link to main JeOS package.
  • If you create package for new board, branch openSUSE:Factory:ARM JeOS to your home and init new package inside it

• .kiwi scipts inside JeOS package are autogenerated using script pre_checkin.sh

• Board specific configs inside JeOS package live in:
  • config.sh
    • Board name and which JeOS flavour will be builded simple or with x and wdm.
  • Images.kiwi.in
    • Here you define additional repos for board, kernel cmdline, u-boot and dtb.
  • uboot-image-setup.in
    • U-Boot kernel loading parameters
  • uboot-image-install.in
    • bootloader update script

• Build localy obs custom jeos package
  • osc build images armv7l
  • may with various binaries not found, check osc meta prjconf it must be same as originate project config.

Create obs packages

• Init new package

$ osc meta pkg -e home:<username> <packagename>

$ osc up home:<username>

• Create .spec file and .changes file
• Test build localy
  • example
  • osc build --alternative-project=openSUSE:Factory:ARM qemu armv7l <.spec file name>
• If it builds fine commit to obs and request to include to upstream
