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.
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:
|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|
- Clone this git repository from your top-level OE directory. For the sake of these instructions, we assume this is '~/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
