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.
Hello World
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:
| Recipe: | Description: | Command: | |
|---|---|---|---|
| myhelloworld | vanilla OE helloworld tutorial | myhelloworld | |
| myhello-cpp | a simple C++ recipe | myhello-cpp | |
| myhello-make | a recipe that uses a Makefile | myhello-make | |
| myhello-cmake | a recipe that uses cmake and creates a library | myhello-cmake | |
| myhello-python | a rather trivial python recipe | myhello-python | |
| myhello-git | shows git fetcher and patching | myhello-git |
Usage
- Clone this git repository from your top-level OE directory. For the sake of these instructions, we assume this is '~/overo-oe'.
$ ~/overo-oe/
$ git clone git://github.com/ashcharles/oe-usercollection.git user.collection
- 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.
$ scp ~/overo-oe/tmp/deploy/glibc/ipk/armv5te/myhelloworld_0.0.1-r0.5_armv5te.ipk root@mygumstixcom:~
- Install your package and test it out:
> opkg install myhelloworld_0.0.1-r0.5_armv5te.ipk
> myhelloworld
Hello world!
