First complete one of the Getting Started tasks.

This task assists the effort of converting the build system for the RTEMS examples-v2.git repository of sample applications from using a set of custom Makefiles to using Waf. Follow the instructions given in the RTEMS GoogleCodeInProjects Wiki page for the directory: examples-v2/posix_api. You will upload a patch file containing the modifications you make. Please also submit your work as a pull request on GitHub.

For this task you will need to determine how to test for whether or not POSIX is enabled before calling recurse() into posix_api.
