I've downloaded SAMA5D4 GNU Software Package 1.2 for Xplained board from http://www.atmel.com/tools/SAMA5D4SOFTWAREPACKAGE.aspx,
and tried to build the projects in there as explained in the documentation folder of that zip file, and by following http://gnuarmeclipse.livius.net/blog/plugins-install/
I haven't been able to succeed a single buid. I used the command line, ARM's editor ARM DS-5, and a plain eclipse.
My build fails on a similar line for each build file in that zip:
