Error with "pip install ./uv_unwrapper/" on Ubuntu

[ropry]

When installing dependencies for ./uv_unwrapper/ using pip, the file uv_unwrapper/csrc/bvh.cpp is compiled:

x86_64-linux-gnu-gcc -fno-strict-overflow -Wsign-compare -DNDEBUG -g -O2 -Wall -fPIC -I/mnt/c/Users/User/Documents/Utils/stable-fast-3d/.venv/lib/python3.12/site-packages/torch/include -I/mnt/c/Users/User/Documents/Utils/stable-fast-3d/.venv/lib/python3.12/site-packages/torch/include/torch/csrc/api/include -I/mnt/c/Users/User/Documents/Utils/stable-fast-3d/.venv/lib/python3.12/site-packages/torch/include/TH -I/mnt/c/Users/User/Documents/Utils/stable-fast-3d/.venv/lib/python3.12/site-packages/torch/include/THC -I/mnt/c/Users/User/Documents/Utils/stable-fast-3d/.venv/include -I/usr/include/python3.12 -c uv_unwrapper/csrc/bvh.cpp -o build/temp.linux-x86_64-cpython-312/uv_unwrapper/csrc/bvh.o -O3 -fdiagnostics-color=always -fopenmp -march=native -DTORCH_API_INCLUDE_EXTENSION_H -DPYBIND11_COMPILER_TYPE=\"_gcc\" -DPYBIND11_STDLIB=\"_libstdcpp\" -DPYBIND11_BUILD_ABI=\"_cxxabi1011\" -DTORCH_EXTENSION_NAME=_C -D_GLIBCXX_USE_CXX11_ABI=0 -std=c++17

On Ubuntu 24.04, the default compiler is gcc-13, which produces the following error:

uv_unwrapper/csrc/bvh.cpp:45:19: error: ‘exchange’ is not a member of ‘std’
   45 |     : triIdx(std::exchange(other.triIdx, nullptr)),

gcc-12 generates a similar error, so it's necessary to downgrade the compiler to gcc-11.

The compiler suggests resolving this issue by modifying the code as follows:

uv_unwrapper/csrc/bvh.cpp:8:1: note: ‘std::exchange’ is defined in header ‘<utility>’; did you forget to ‘#include <utility>’?
    7 | #include <queue>
  +++ |+#include <utility>
    8 | #include <tuple>

Maybe it would be better to add #include <utility> to uv_unwrapper/csrc/bvh.cpp to avoid downgrading the compiler version?
