I've found the -mcpu can be changed to -mtune using the same parameter to remove the -mcpu error, however, we don't see a work around for the other two errors.
We're compiling on ubuntu on a VirtualBox VM running on Win7 with the Jetson TK1 installed. Have this been seen before? Any suggestions?
Thank you.

Looks like you're compiling for x86 rather than ARM. Remove those two ARM-specific options and the code should build correctly. Or alternatively, you could push the code to a Jetson board and build there and things should just work.
If you're trying to cross-compile (build ARM binaries on an x86 Linux host machine) you'll need to point to the correct compiler. The compiler name is usually of the form "arm-none-linux-gnueabihf-g++" or the like. Sometimes "none" is called "unknown" instead, but the general idea is the same.
If you are planning to run on x86, be aware that the code is written to run on the GPU. If I remember there are fallbacks to run on the CPU, but the CPU code wasn't the focus of our development effort so it may be different than the GPU code.
