	On Linux, depending on your GCC version you might get this error.	On Linux, depending on your GCC version you might get this error. There are two possible solutions:

	If so, delete the following line in ``/usr/local/cuda/include/host_config.h``	Use an alternate compiler
		If you have a CUDA-compatible GCC installed under an alternate name, such as ``cuda-gcc``,
		you can tell Cycles to use that version by setting the ``CYCLES_CUDA_EXTRA_CFLAGS``
		environment variable when starting blender.

	::	Launch Blender from the command line as follows:

	#error -- unsupported GNU version! gcc 4.7 and up are not supported!	.. code-block:: sh

		CYCLES_CUDA_EXTRA_CFLAGS="-ccbin cuda-gcc" blender

		(Substitute the name or path of your CUDA-compatible compiler, if it is called something
		other than ``cuda-gcc``.)

		This will allow Cycles to successfully compile the CUDA rendering kernel the first time it
		attempts to use your GPU for rendering. Once the kernel is built successfully, you can
		launch Blender as you normally would and the CUDA kernel will still be used for rendering.

		Remove compatibility checks
		As a last resort if the above is unsuccessful, delete the following line in
		``/usr/local/cuda/include/host_config.h``
