You should read these repair guidelines if you see the “conf / bitbake.conf file not found” error on your computer.
Create Project Directory
Run Bitbake
When you start BitBake, it starts searching based on the metadata files. The bbpath variable tells BitBake where to look for files. BBPATH is undefined and must be stopped. Without BBPATH, Bitbake cannot find the configuration file (.conf) or recipe file (.bb). BitBake also cannot find the bitbake.conf file.
Define BBPATH
This experiment shows BitBake that the conf / bitbake.conf file in the project phonebook file cannot be counted. This file is the first thing BitBake needs to find in order to create its own target. Since the project directory is empty in this example, you must provide a conf / bitbake.conf file. Impossible error: on parse path conf / bitbake.conf: [Errno 2] The conf / bitbake.conf file is far from / home / peter / work / examples / hello
Create Conf / Bitbake.conf

Use an editor from each conf directory to create a bitbake the.conf that will contain:
The any TMPDIR variable creates a directory that BitBake uses to output the build and intermediate personal entries (excluding the cached information that is used as a result of the setscene process. The TMPDIR directory is important here, let it be hello / tmp is.
Run Bitbake
In the sample output, BitBake usually cannot find the classes / base.bbclass file. Then you have to create a file.
Create Classes / Base.bbclass
BitBake uses class files to show you general code and functions. The minimum class required for BitBake is the data classes / base.bbclass. The base class is implicitly inherited with every recipe. BitBake looks for a university in the assessment class directory (e.g. hello / classes in this example).
Go to the class directory, then create each of our base.File bbclass by adding this single line:
The smart task that BitBake does is every do_build task. This is the example you need to provide to create a project. Of course base.bbclass can have a lot more, dependingFrom the build environment supported by BitBake. More information on the base.bbclass file can be found at http://hambedded.org/blog/2012/11/24/from-bitbake-hello-world-to-an-image/#tasks.
Run Is Bitbake
Finally,
bitbake does not report errors. However, you and your family understand that this has nothing to do with it. You have to create a marketable recipe that BitBake has for everything you can do.
Create Layer
While not necessary for such a small illustration, it is recommended that you create a layer that separates the computer code from the general metadata used in BitBake. Thus, in this example, a layer called “my layer” is created and processed.CommentFor more information on the extra layer see http://hambedded.org/blog/2012/11/24/from-bitbake-hello-world-to-an-image/#adding-an-example-layer.
You will need at least one recipe file and one config file for each layer in your layer. The config file must be in every conf directory at the.
To create a recipe, you need the following file. Use the app and create a recipe file linkedwith printhello.bb which contains:
Start Bitbake With An Important Purpose
We’ve created a layer with the exact recipe and layer configuration, but note that it looks like BitBake is unable to deliver the recipe. BitBake needs conf / bblayers. This configuration provides layers for the project. Without the file, BitBake cannot find your current recipe.
Create Conf / Bblayers.conf
BitBake uses conf / bblayers.File conf to recognize the layers needed for the project. It should be in the conf directory behind the project (e.g. hello / conf for this example situation).
Install the hello / conf database in your directory, then create a bblayers.conf file for you to manually register and enable:

After the first run, running bitbake printhello again as soon as possible does not cause BitBake to create a disk that prints the same console output. This is because the first time the do_build task from the printhello.bb recipe succeeds, BitBake writes the file buffer associated with that task. This way, the next time you try to run a task with the same Bitbake instruction, BitBake will notice the buffer and therefore determine that the task does not need to be rerun. If everything removes the tmp directory or runs bitbake clean -c printhell
