Clangd doesn't recognize standard headers

[CodeZHXS]

I'm trying to compile Postgres-17 using bear to generate compile_commands.json:

./configure --enable-debug --enable-cassert CFLAGS=-O0
bear -- make -j

This successfully produces the compile_commands.json file in the directory.

When using the ms-c/c++ extension in VSCode, everything works fine once I specify the path. However, after disabling the ms-c/c++ plugin and enabling the clangd plugin, I encounter errors. It appears that certain headers, such as stdbool.h, are not being recognized correctly. For reference, stdbool.h is located at /usr/lib/gcc/x86_64-linux-gnu/11/include.

tried adding the following to my settings.json:

"clangd.arguments": ["--query-driver=/usr/bin/gcc"]

But this did not resolve the issue.

How can I fix this?

Can you post verbose logs please (--log=verbose in "clangd.arguments")?

Sure, I have replaced the verbose log in my description.

Based on the log, standard library includes like <stdbool.h> are resolved fine.

The issue seems to be that bufmgr.h is not a self-contained file (https://github.com/clangd/clangd/issues/45). It does not directly or indirectly include (for example) <stdbool.h>, and as a result symbols defined in <stdbool.h> (such as the macro bool) are not resolved. If I add #include <stdbool.h> at the top of bufmgr.h, bool now becomes resolved.

Manually adding header files seems a bit cumbersome. In fact, I have to frequently switch to Microsoft's c++ tools to know which header file I should import.
