Header Files#

SYCL provides a single standard header file:

#include <sycl/sycl.hpp>

which needs to be included in every translation unit that uses the SYCL programming API.

For compatibility with the earlier version; SYCL 1.2.1, SYCL also provides another header file:

#include <CL/sycl.hpp>

which can be used in place of sycl/sycl.hpp, providing all of the same SYCL programming API, though it is recommended to use sycl/sycl.hpp.

Extension headers are available in sycl/ext/ include paths and backend- specific headers are available in sycl/backend/ include paths.
