@Racer84 The only change in 1.18.5 was https://github.com/microsoft/vscode-cpptools/issues/11693 -- i.e. the issue is caused by the default database location not being usable for some reason. Setting C_Cpp.default.databaseFilename to something like "${workspaceFolder}/.vscode/vc.db" might fix it (it should a be file that isn't duplicated in other workspaces).

Do you have the XDG_CACHE_HOME environment variable set? Is your ~/.cache directory not writable? Is your workspace done "parsing files"?

Do you have the XDG_CACHE_HOME environment variable set?

No, I don't.

Is your ~/.cache directory not writable?

No, it is writable.

Is your workspace done "parsing files"?

Yes, status is "Parsing complete".

@Racer84 Have you modified the databaseFilename? If not, can you go to the default location of ~/.cache/vscode-cpptools/ use ls -l and see which guid folder is the most recently updated and the go into that folder and use ls -a and see if you see .browse.VC.db files of size > 0.

@Racer84 Does running the C/C++: Reset IntelliSense Database command from the command palette fix it? Is the .browse.VC.db creation date updated after that?

I've just upgraded vscode to 1.85.0 and outline problem is no more.

Dec 08 '23 09:12 Racer84

BTW. Since the 1.18.5 changes cache folder location to ~/.cache/vscode-cpptools previous location ~/vscode-cpptools should be removed.

Dec 08 '23 12:12 Racer84

@browntarik when the cache path changed, I thought you added code to remove the old location. Did that not make it in?

I am experiencing this problem also. But only when editing a workspace on a remote ssh linux server. My local machine is MacOS and the symbols load fine on the local machine. This used to work on the remote machine, but no longer does. I followed all of the recommendations in this thread, but still no luck.

I tried it in the pre-release version 1.19.1 and it it works again in that version.

@bobbrow No code was added to remove previous location of ~/vscode-cpptools (that wasn't the intended location). See https://github.com/microsoft/vscode-cpptools/pull/11696

Same issues occurred when connecting from Windows 11 to a local VM running Ubuntu Server. After executing the shell command rm ~/.cache/vscode-cpptools/* and running the command Developer: Reload Window from the command palette, the problem was resolved.

I don't know if this is related but I am having a similar, yet weirder issue, on version 1.85.1 in Linux. The very same file will show a correct outline if I open it as a file. No outline is shown if I open it as a folder. This applies to all Python files of course not just this one.
