Error when installing mmcv

[Eden-Wang1710]

Thanks for your interesting project!
My cuda is 11.8, the same with yours.
The following is the error when running pip install -v -e .:

Installing collected packages: mmcv

  DEPRECATION: Legacy editable install of mmcv==0.0.1 from file:///home/work/Bench2Drive/Bench2DriveZoo (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information.

Hi @Eden-Wang1710 , see #22. You need to pay attention to GCC/G++ Version, CUDA Version.
If they don't solve your problem, please provide the full terminal log.

Fixed, with following environment:
-cuda_11.8
-Ubuntu 18.04
-gcc (GCC) 9.4.0
