Yocto Toolchain installation
Prerequisites
A full Debian build environment is required for the toolchain generation.
To setup a Debian build environment follow steps 1 & 3 of the Build Debian from source code guide and then proceed to either the toolchain or complete SDK steps below:
Build a toolchain
Setup the environment:
$ cd ~/debian_imx8qm-var-som $ MACHINE=imx8qm-var-som DISTRO=fsl-imx-xwayland MACHINE=imx8qm-var-som ./var_make_debian.sh build_xwayland
Build the toolchain:
$ bitbake meta-toolchain
Install the toolchain/SDK
Install the tools by running the resulted script in tmp/deploy/sdk/.
E.g.
$ tmp/deploy/sdk/fsl-imx-xwayland-glibc-x86_64-fsl-image-gui-aarch64-toolchain-4.14-sumo.sh
Note: The toolchain/script name depends on your build machine and the bitbaked image/recipe, and may change.
Accept all the default options, and at the end of the installation you should see the following:
SDK has been successfully set up and is ready to be used.
Use the toolchain/SDK
Each time you wish to use the toolchain in a new shell session, you need to source the environment setup script:
$ source /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux
$ export LDFLAGS=
