Toolchain installation for out of Yocto builds
Build the toolchain by:
$ bitbake meta-ide-support $ bitbake meta-toolchain
The output will be located at tmp/deploy/sdk/. On a 64 bit Ubuntu you will get:
sdk/poky-eglibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh
Install the tools by running:
$ tmp/deploy/sdk/poky-eglibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh
Reply to all defaults 'y'
The toolchain name depend on your build machine and may change.
