It is so weird why my installation failed at here.

gaussian-splatting/SIBR_viewers/src/./projects/remote/json.hpp:3954:14: fatal error: filesystem: No such file or directory

#include < filesystem >

My environment is ubuntu 2204 cmake 3.24 gcc 7.5 cuda 11.8

Hi,

gcc 7 is too old, it does not have a working filesystem implementation (does not fulfill that part of the C++17 standard)

[yifeilang]

#include <experimental/filesystem> std::experimental::filesystem::xxx

replace filesystem with experimental filesystem

[ZefuLin]

#include <experimental/filesystem> std::experimental::filesystem::xxx

replace filesystem with experimental filesystem

It works for me, thank you!
