Yocto Toolchain installation

Yocto toolchain installation for out of Yocto builds

Assuming you followed steps 1, 3, 4 & 5 of the Build Yocto from source code guide, as an example of X11 build, build the toolchain by:

$ cd ~/var-fslc-yocto
$ MACHINE=var-som-mx6 DISTRO=fslc-x11 . setup-environment build_x11
$ bitbake meta-ide-support
$ bitbake meta-toolchain

The output will be located at tmp/deploy/sdk/. On a 64 bit Ubuntu you will get the following script.

Install the tools by running it:

$ tmp/deploy/sdk/fslc-x11-glibc-x86_64-meta-toolchain-armv7at2hf-neon-toolchain-2.2.1.sh

The toolchain name depend on your build machine and may change.

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-x11/4.1.15-2.0.1/environment-setup-cortexa7hf-neon-poky-linux-gnueabi
