wrong pp_file_not_found
clangd hint me In included file: 'Eigen/Core' file not foundclang(pp_file_not_found)
but my compile_commands.json clear include the eigen package

similar question on windows, msvc 2022, this is the simple code
#include <boost/chrono.hpp> // always report not found, but compile is ok, and file jump is also ok
#include <iostream>
int main()
{
boost::chrono::nanoseconds ns;
return 0;
}
this is the output log

i'm sure compile is ok, but the intellisense always not found, the file jump is also ok.

looks like no problem.
and I have disabled C_Cpp tools, this is my vscode setting.json

@shxygray Please file a new issue for further discussion of your Boost-related error. The OP's issue is about a different library (Eigen) on a different platform (Linux), and it just confuses things to be diagnosing different issues in the same thread.
In your logs:
"message": "'boost/chrono.hp' file not found",
suggests this diagnostic is from a state of the file where the last letter of chrono.hpp was not typed yet.
So, maybe it's a stale diagnostic? Is it still there if you restart clangd? If yes, please provide a new log that shows the diagnostic with the correct header spelling.
@HighCommander4 I resolved my problem, seem like the C/C++ Clang Command Adapter plugin cause it. I disabled the plugin, and now intellisense is fine.
otherwise, I tried it for wsl ubuntu, g++, the include hint is also "file not found", I don't know why, but now it works fine.
