build_simple_kernel() [1/2]

boost::compute::kernel jb::opencl::build_simple_kernel	(	boost::compute::context	context,
		boost::compute::device	device,
		char const *	code,
		char const *	kernel_name
	)

Build a simple program (one where everything is in a single string) and get a kernel from it.

Most of our kernels are relatively simple, so this routine is very convenient.

boost::compute::kernel jb::opencl::build_simple_kernel	(	boost::compute::context	context,
		boost::compute::device	device,
		std::istream &	code,
		char const *	kernel_name
	)

Build a simple program from an iostream and get a kernel from the result.

		boost::compute::device	device,
		char const *	code
	)

Convenience function to build a simple program and return it.

Build a problem that consists of a single source string, targeted to a single device.
