You could send your source to someone who has a copy of Wind River installed. I think
kamokat has it working.
As a last resort, NI posted instructions on how to build programs for the cRIO with just a modified version of gcc (no Wind River needed). Make sure to grab vxworks61gccdist.zip at the bottom of the page. Your .out file needs to be named FRC_UserProgram.out
