Building the Linux kernel
In this recipe, we will go through the development workflows described earlier using the Linux kernel as an example.
How to do it...
We will see how the following development workflows are applied to the Linux kernel:
- External development
- Working directory development
- External source development
How it works...
Let's explain the three methodologies listed previously in detail.
When compiling outside of the Yocto build environment, we can still use the Yocto-provided toolchain to build. The process is as follows:
- We will use the Yocto project cross-compilation toolchain already installed in your host.
- Clone the
wandboard-org linux-wandboardrepository locally:
$ cd /opt/yocto $ git clone https://github.com/wandboard-org/linux.git ...
