Failed To Generate DataConverter C++ Component

Question

I am trying to modify the DataConverter component from the REDHAWK repo on GitHub (https://github.com/RedhawkSDR/basic-components/tree/master/DataConverter) to convert data from float to the complex float data type, so I send data can send data to be transmitted by the USRP (which only accepts complex float as an input).

However, after I added the new ports and properties for the complex float data type I went to generate the component and received the error

GENERATE FAILED: Failed to find implementation settings for implementation DCE:f744f32f-510a-4e64-9124-3507d5568e39

When I look at the Implementations tab of the DataConverter.spd.xml I noticed the section named "Code Generation Details" is missing. The content of DataConvert.spd.xml is below. For reference, I'm running REDHAWK 1.9 on Centos 6.4 x64.

It looks like a required hidden file from the project has been removed, specifically ".DataConverter.wavedev". The file which ties the component's implementation to a specific code generator is called the wavedev file. For more information on the hidden files used by the Eclipse IDE see Chapter 20.1.1 in the v1.9 REDHAWK documentation.

If you cloned this project from the git repository you should be able to confirm this using git status. If this is the case, you can use git commands to re-checkout this missing file. From the root of the basic-components repository:

git checkout DataConverter/.DataConverter.wavedev

The wavedev file for this project may also be viewed here
