Is the intel-basekit missing a dependency?


When I install the intel base-kit on Ubuntu Linux 18.04.6, I see these dependencies:

Because intel-oneapi-compiler-dpcpp-cpp-common is not being included, I saw this failure when I tried to build the hello_world.cpp program provided by ShivaniK_Intel, I saw this:

toddb@zippy $ icx -fsycl -fsycl-unnamed-lambda hello_world.cpp
hello_world.cpp:1:10: fatal error: 'CL/sycl.hpp' file not found
#include <CL/sycl.hpp>
1 error generated.

I fixed this by installing the missing package myself:

apt install intel-oneapi-compiler-dpcpp-cpp-common

But now I am seeing this error:

toddb@zippy $ dpcpp hello_world.cpp
In file included from hello_world.cpp:1:

/opt/intel/oneapi/compiler/latest/linux/include/sycl/CL/sycl/types.hpp:2333:20: note: declared here

Does anyone know what the issue is with this error? I am only trying to get a hello_world.cpp, which was provided by an Intel employee, working. I don't know why this is so hard. It makes me wonder how many more issues might come up if I start using oneAPI in projects.

Thank you,
