1. Overview[edit source]
OpenEmbedded is a build system to generate distributions via images or to generate a SDK.
A tool is available on OpenEmbedded to step into development with your OpenEmbedded distribution, this tool is named devtool.
This tool allows to:
- add new recipe
- create append on actual recipe by creating bbappend file
- update existing bbappend file
Display devtool help:
$ devtool --help

2. Examples[edit source]
2.1. Add a new application or a new library[edit source]
2.1.1. Goal[edit source]
The goal is to integrate a new application or a new library on your OpenEmbedded build setup.
The application or library doesn't have any recipe available on any layer referenced by your OpenEmbedded build setup.
Devtool can help you to generate recipe in your OpenEmbedded build setup and more specifically in a layer you manage.
2.1.2. Way of working (step-by-step)[edit source]
1. Create a source directory if does not exist (example 'mysources' in build dir)
$> mkdir mysources/myapp
2. Get the source of application (git clone, extract tarball, ...) and put it in the source directory
3. Add the application to the workspace
$> devtool add myapp mysources/myapp
(devtool create on workspace a recipe for myapp, see description of command devtool add.)
4. Build it:
$> devtool build myapp
5. Deploy to the target device build output (via network access)
$> devtool deploy-target myapp root@<ip of board>
6. Edit source code & repeat 4-5 as necessary
7. Populate the layer with your new recipe
First, make sure to create/enable your custom layer meta-my-custo-layer. For that you can refer to How to create a new open embedded layer article.
$> mkdir ../meta-st/meta-my-custo-layer/recipes-custom/myapp $> cp workspace/recipes/myapp/myapp.bb ../meta-st/meta-my-custo-layer/recipes-custom/myapp $> mkdir ../meta-st/meta-my-custo-layer/recipes-custom/myapp/myapp $> cp mysources/myapp/* ../meta-st/meta-my-custo-layer/recipes-custom/myapp/myapp $> cp <appropriated license file> ../meta-st/meta-my-custo-layer/recipes-custom/myapp/myapp
Note that all copied files into folder ../meta-st/meta-my-custo-layer/recipes-custom/myapp/myapp must be added in SRC_URI field of myapp.bb
Then the new recipe (myapp.bb) must be added inside the custom image you compile
$> cd meta-st/meta-my-custo-layer/recipes-samples/images/
Open my-custom-image.bb and add this line : IMAGE_INSTALL += "myapp"
2.1.3. Material[edit source]
- content of recipe file
$> cat workspace/recipes/myapp/myapp.bb # Recipe created by recipetool # This is the basis of a recipe and may need further editing in order to be fully functional. # (Feel free to remove these comments when editing.) # # WARNING: the following LICENSE and LIC_FILES_CHKSUM values are best guesses - it is # your responsibility to verify that the values are complete and correct.

2.2. modify an existing application or library managed by a recipe on which you have the ownership[edit source]
2.2.1. Goal[edit source]
The goal is to update a recipe owned by you.
On the following example, we take the library libsmaf on which we would like to apply some modifications.
2.2.2. Way of working (step-by-step)[edit source]
1. Create a source directory (example 'mysources' in build dir)
$> mkdir mysources
2. Extract source
$> devtool modify -x libsmaf mysources/libsmaf
(option -x: request to devtool to extract the source code and patch it following
the rules available on libsmaf recipe.)
3. Edit the code and/or commit your changes on local git repository
4. Build it:
$> devtool build libsmaf
5. Deploy to the target device build output (via network access)
$> devtool deploy-target libsmaf root@<ip of board>
6. Edit source code & repeat 3-5 as necessary
7. Write as patches on top of recipe
$> devtool update-recipe -a ../meta-st/meta-my-custo-layer libsmaf
First, make sure to create/enable your custom layer meta-my-custo-layer. For that you can refer to How to create a new open embedded layer article.
8. Come back to normal (remove the component from workspace)
$> devtool reset libsmaf
2.2.3. Material[edit source]
- modification made by devtool on libsmaf.bb
$> git diff recipessecurity/smaf/libsmaf.bb diff git a/recipessecurity/smaf/libsmaf.bb b/recipessecurity/smaf/libsmaf.bb index 78d5882..6c04a2f 100644 a/recipessecurity/smaf/libsmaf.bb +++ b/recipessecurity/smaf/libsmaf.bb @@ 8,7 +8,9 @@ PV="1.0+git" inherit autotools gettext pkgconfig -SRC_URI = "git://github.com/cpriouzeau/libsmaf.git;protocol=https" +SRC_URI = "git://github.com/cpriouzeau/libsmaf.git;protocol=https \ + file://0001Someschanges.patch \ + " S = "${WORKDIR}/git"

2.3. Create/update an append on application or library[edit source]
2.3.1. Goal[edit source]
The goal are to update (or create) an append made for a specific recipe.
On this example, we take the library pixman on which we are would like to apply some modification.
2.3.2. Way of working (step by step)[edit source]
1. Create a source directory if not exist (here mysources on build dir)
$> mkdir mysources
2. Extract source
$> devtool modify -x pixman mysources/pixman
3. Edit the code and/or commit your change on local git repository
4. Build it:
$> devtool build pixman
5. Deploy to target device build output (via network access)
$> devtool deploy-target pixman root@<ip of board>
6. Edit source code & repeat 3-5 as necessary
7. Write as patches on top of recipe append file
$> devtool update-recipe -a ../meta-st/meta-my-custo-layer pixman
First, make sure to create/enable your custom layer meta-my-custo-layer. For that you can refer to How to create a new open embedded layer article. Then:
8. Come back to normal (remove the component of workspace)
$> devtool reset pixman
2.3.3. Material[edit source]

followed by reset, except the update-recipe step will do the "right thing"
depending on the recipe and the destination layer specified.
arguments:
recipename Recipe to finish
destination Layer/path to put recipe into. Can be the name of a
layer configured in your bblayers.conf, the path to
the base of a layer, or a partial path inside a layer.
