Pre-requisites

• Build docker image A based docker image must be built previously. See https://github.com/py4mac/dotfiles

• Run docker env

docker-compose run virtual-env

NOTE: In case of issue, increase watch file using command sudo sysctl -n -w fs.inotify.max_user_watches=1048576

Steps

• Collect dependencies repo

repo init -u https://github.com/py4mac/yocto-manifest.git -b main -m manifest.xml
repo sync
source layers/poky/oe-init-build-env ./builds/build-x86

• Add noclue layer

bitbake-layers add-layer ../../layers/py4mac/meta-noclue

• Build image

bitbake noclue-image

• Test image

runqemu nographic slirp

login is root and password is root

The new binary file imported is then

noclue

• Exit

halt

Tips

Create a new layer before building (see initial build step)

• Create noclue layer

bitbake-layers create-layer ../../layers/meta-noclue

• Add noclue layer

bitbake-layers add-layer ../../layers/meta-noclue

• Build core image

bitbake core-image-minimal

Add C/C++ image

At the same level than poky, create noclue folder with C/C++ code + CMakeLists and type devtool add --no-same-dir ../../noclue

Copy *.bb files and *.bbappend files in meta-noclue folder (meta-noclue/recipes-noclue/c)

Create image in meta-noclue/recipes-noclue/images/noclue-image.bb folder with content:

require recipes-core/images/core-image-minimal.bb

IMAGE_INSTALL += "noclue"

Then

bitbake noclue
bitbake noclue-image
