• Qiskit Aer version: master or 0.15
• Python version: 3.12
• Operating system: Linux

What is the current behavior?

The code does not compile using CUDA 12.4 and gcc 12.3

Steps to reproduce the problem

python3.12 ./setup.py bdist_wheel -- -DAER_THRUST_BACKEND=CUDA -DAER_CUDA_ARCH="9.0" -DCUQUANTUM_ROOT=/users/diehlpk/compile/cuquantum-linux-sbsa-24.08.0.5_cuda12-archive --

What is the expected behavior?

The code should compile

Suggested solutions

I played around changing the C++ code but could not solve it

Ok, after further debugging it seems the issue is not gcc 12.3 and it is the nvcc compiler wrapper.

Ok, it seems to be the combination of the cuda version with gcc 12 and it works with gcc 13
