Bitbake Clean And Build

Bitbake scripts cetola also gave a shout out to some of his favorite bitbake scripts starting with devtool which the yocto project wiki describes as a way to mix customization into a yocto image.

Bitbake clean and build. Changes are lost if you remove the tmpdir or do a bitbake c clean virtual kernel so you may consider replacing the defconfig with it. It is very useful if you work on a new bb recipe. Other options include the e option which outputs the bitbake environment and c command for invalidating a stamp specific clean. So alas the question needs to be asked.

It is not clear or documented if it cleans all build time dependencies as well. I need to modify source code and build it. To get a package build just type bitbake foo where foo is the name of the package without any extension or version number. Note by default bitbake cleans the environment to include only those things exported or listed in its whitelist to ensure that the build environment is reproducible and consistent.

This command will open a new terminal in the package s build directory with bitbake s environment set up after the source files have been fetched and all compile time dependencies have been built but before any configure compile steps for the package have been taken. Bitbake cleanall removes all output files shared state cache and downloaded source files for a target. Bitbake virtual kernel after done you can collect the built image from under the deploy folder. The devshell is the scalpel of bitbake troubleshooting.

Today bitbake is the primary basis of the openembedded project which is being used to build and maintain linux distributions such as the angstrom distribution and which is used as the build tool for linux projects such as the yocto project. So i gave bitbake c clean package name followed by bitbake package name. What do you want to clean out and why. So all bitbake core image minimal c clean f will actually clean is the working directory where the system image was built.

Bitbake c listtasks core image minimal do build default task for a recipe depends on all other normal tasks required to build a recipe do bundle initramfs combines an initial ramdisk image and kernel together to form a single image do checkuri validates the src uri value do checkuriall validates the src uri value for all recipes required to build a target do clean removes all output files. All the rest of the stuff the kernel the shell commands the compilers used to build everything stays around. Prior to bitbake no other build tool adequately met the needs of an aspiring embedded linux distribution. The image got built.

When running a task bitbake tightly controls the shell execution environment of the build tasks to make sure unwanted contamination from the build machine cannot influence the build. Feel free to add all your usual bitbake commands to this page start a build. For a default build just run. I wanted to rebuild the source.
