On a linux server, my gcc and g++ version are 4.8.5, when i run 'pip install hnswlib' : Collecting hnswlib Using cached hnswlib-0.7.0.tar.gz (33 kB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing metadata (pyproject.toml) ... done Requirement already satisfied: numpy in /.../miniconda3/envs/bio_torch/lib/python3.9/site-packages (from hnswlib) (1.23.4) Building wheels for collected packages: hnswlib Building wheel for hnswlib (pyproject.toml) ... error error: subprocess-exited-with-error

I am not the administrator, so i can't upgrade gcc... Thanks a lot

I do not think there much we can do from our side. C++11 is basically a necessity right now.

One things that you can do is install/compile a newer GCC on your machine or install it via conda (something like conda install -c conda-forge gcc). That should not require root privileges

Thanks, i've done this on a new server.

apt install -y gcc-10 g++-10 cpp-10 CC=/usr/bin/gcc-10 pip3 install hnswlib Fixes the issue for me .

I was getting the same issue in MacOS. My issue was resolved when I upgraded the Python version from 3.8 to 3.11.
