OneAPI 2023.0 clang++ doesn't link with standard library Ubuntu 22.04 LTS.

I've just installed the newly released 2023.0.0 OneAPI Base Toolkit on my Ubuntu 22.04 LTS machine. CUDA 12.0 and the Codeplay Nvidia add-on have also been installed.

Attempting to run the Getting Started from Codeplay I encounter issues with Intel's clang++ not finding or linking to the linux headers. In fact, this issue occurs even for a hello world program not  finding iostream.

Printing out my CPATH environment variable gives

/opt/intel/oneapi/vpl/2023.0.0/include:/opt/intel/oneapi/tbb/2021.8.0/env/../include:/opt/intel/oneapi/mpi/2021.8.0//include:/opt/intel/oneapi/mkl/2023.0.0/include:/opt/intel/oneapi/ipp/2021.7.0/include:/opt/intel/oneapi/ippcp/2021.6.3/include:/opt/intel/oneapi/ipp/2021.7.0/include:/opt/intel/oneapi/dpl/2022.0.0/linux/include:/opt/intel/oneapi/dpcpp-ct/2023.0.0/include:/opt/intel/oneapi/dnnl/2023.0.0/cpu_dpcpp_gpu_dpcpp/include:/opt/intel/oneapi/dev-utilities/2021.8.0/include:/opt/intel/oneapi/dal/2023.0.0/include:/opt/intel/oneapi/ccl/2021.8.0/include/cpu_gpu_dpcpp

Adding /usr/include/c++/11/ and /usr/include/x86_64-linux-gnu/c++/11 as found elsewhere on the internet to CPATH so it can find cstddef I then get

/usr/bin/ld: cannot find -lstdc++: No such file or directory

I've had no issues developing with C++ and CUDA using gcc/g++ and nvcc prior to this, and I've followed and installed all packages mentioned by the Intel OneAPI and Codeplay guides and installers.

What configuration do I need to provide to have the OneAPI clang++ link against the standard library correctly?

I was able to resolve the issue on my own.

Running clang++ -v revealed clang was linking against the gcc-12 headers / libraries. However, these actually weren't present on my system. The solution to this was to additionally install the g++-12 package with

sudo apt install g++-12
