When I try to compile and run the demos, I am getting following error(s):
error: #error "GCC no longer implements <varargs.h>."
error: #error: "Revise your code to use <stdarg.h>."
New GCC compiler for Linux has caused this.
If you modify the Makefiles wherever you see "$(XRTHOME)/bin/xrt_gmf" to read "$(XRTHOME)/bin/xrt_gmf -a" the problem will disappear.
The Makefiles will be updated by default in the next release.
