This page documents cuda::std::version in libhipcxx, which defines version macros for tracking library and feature availability.
See the documentation of the standard header <version>
Extensions#
The following version macros, which are explained in the versioning section, are defined in this header:
_LIBCUDACXX_CUDA_API_VERSION_LIBCUDACXX_CUDA_API_VERSION_MAJOR_LIBCUDACXX_CUDA_API_VERSION_MINOR_LIBCUDACXX_CUDA_API_VERSION_PATCH_LIBCUDACXX_CUDA_ABI_VERSION_LIBCUDACXX_CUDA_ABI_VERSION_LATEST
Restrictions#
<cuda/std/version> includes the host standard library’s <version> header, so the standard C++ feature test
macros are defined by the host standard library, not by libhipcxx. libhipcxx defines its own __cccl_lib_* macros
for the features it provides.
