Qt includes not found - Githubissues

Being on macOS with Apple Silicon here. (Sonoma)

So I tried using VSC clangd but it cannot find symlinks.

In settings.json I have:

    "clangd.arguments": ["-log=verbose", 
                         "-pretty", 
                         "--background-index", 
                         "--compile-commands-dir=/Users/michael/Private/MyWorkspace/MyProject/build/src/compile_commands.json"],

The compile_commands file is recognized because all my internal symbols work nicely.

Maybe an excerpt from my compile_commands.json file:

},

If I follow through myself, I see that:

/Users/michael/Private/MyWorkspace/MyProject/libs/6.4.2/macos/lib/QtCore.framework/Headers

is a symlink to

Versions/Current/Headers

while Versions/Current is a symlink to A. So in essence (and this works with the "normal" VSC c/c++ intellisense) the whole think goes to:

/Users/michael/Private/MyWorkspace/MyProject/libs/6.4.2/macos/lib/QtCore.framework/Versions/A/Headers

And there I find a file like QAbstractItemModel. However, clangd tells me, it cannot find it.

Verbose logs are enabled, the relevant part is probably this (at least searching for QAbstractItemModel does not reveal anything better):

              },

            },

          }
        ],
        "severity": 1,

      },

My unqualified assumption is that clangd has problems with this "symlink-complicated" Qt include structure. No clue why but it's definitely annoying. Any idea?

It can probably be rather macos-clangd-related. Then again, I think QtCreator also uses clangd but clearly works. So I'm a bit puzzled now.

clangd / vscode-clangd
