| − | The OpenEmbedded (OE) manual introduces Bitbake recipes using a single 'helloworld' tutorial. While this is a useful introduction, there are many other common use cases.
| + | This page has been superseded by the infomation [https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html#hello-world-example here]. |

| − | The git repository given below contains a user.collections directory complete with a number of sample helloworld recipes elucidating different use cases. An explanation for each is given below:

| − | ==Usage==
| + | |
| − | # Clone this git repository from your top-level OE directory. For the sake of these instructions, we assume this is '~/overo-oe'.
| + | |
| − | #:<pre>$ ~/overo-oe/ </pre>
| + | |
| − | #:<pre>$ git clone git://github.com/ashcharles/oe-usercollection.git user.collection</pre>
| + | |
| − | #:'''Note:''' If you already have a ''user.collection'' directory, you might like to clone the repository by its default name (oe-usercollection) and then let bitbake know about this folder. See the ''extras'' folder inside the recipe for hints on this.
| + | |
| − | # Bitbake the desired recipe based on its recipe name e.g. ''bitbake myhello-cpp''
| + | |
| − | # Copy the newly created package file from your build machine to your Gumstix. You might do this by transfering the files on microSD card, using a serial connection, or, most simply, copying them over an internet connection. E.g.
| + | |
| − | #:<pre>$ scp ~/overo-oe/tmp/deploy/glibc/ipk/armv5te/myhelloworld_0.0.1-r0.5_armv5te.ipk root@mygumstixcom:~ </pre>
| + | |
| − | # Install your package and test it out:
| + | |
| − | #:<pre>> opkg install myhelloworld_0.0.1-r0.5_armv5te.ipk </pre>
| + | |
| − | #:<pre>> myhelloworld </pre>
| + | |
| − | #:<pre>Hello world! </pre>
