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:

<table>

<tr>
+
<th>Recipe:</th><th>Description:</th><th>Command:</th>
+
</tr><tr>
+
<td>myhelloworld</td><td>vanilla OE helloworld tutorial</td><td>myhelloworld</td>
+
</tr><tr>
+
<td>myhello-cpp</td><td>a simple C++ recipe</td><td>myhello-cpp<td>
+
</tr><tr>
+
<td>myhello-make</td><td>a recipe that uses a Makefile</td><td>myhello-make<td>
+
</tr><tr>
+
<td>myhello-cmake</td><td>a recipe that uses cmake and creates a library</td><td>myhello-cmake<td>
+
</tr><tr>
+
<td>myhello-python</td><td>a rather trivial python recipe</td><td>myhello-python<td>
+
</tr><tr>

==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>
+
