Target platform
The last version of the project contains the plug-in org.eclipse.osatesphinx.targetdefs that defines a target platform definition. This target platform provides all we need to compile the sources. It contains among other the Sphinx and the Osate 2.0.2 sources.
To compile the sources, open the osate-sphinx-adopter-4.2.target file into Eclipse and click on Set as Target Platform after that the target definition has been resolved.
