Intellisense doesn't work at all

babaoglu53 commented 2 weeks ago

Environment

OS and Version: Windows 11 Pro 23H2
VS Code Version: 1.94.2
C/C++ Extension Version: v1.22.10
If using SSH remote, specify OS of remote machine: CentOS Linux release 7.9.2009 (Core)

Bug Summary and Steps to Reproduce

Bug Summary: Intellisense hasn't been working for about a week even though I haven't made any changes. includePath and cannot open source file error. In standard C++ libraries it doesn't give errors, but this time it doesn't find references. When I add my own libraries, it doesn't work at all.

What I tried:

I updated includePath. I gave fullpath into includePath one by one.
I tried on another centos machine and it works there.
I installed the old version of cpp extension.
I tried it on WSL2 and it works
I completely deleted the vscode-server folder on the remote server and reinstalled everything

Everything was normal until a week ago, but suddenly it stopped working.

I encountered the same problem...

sean-mcmanus commented 2 weeks ago

@babaoglu53 @huttuh When you run the C/C++: Log Diagnostics command, do you see it repot an invalid configuration? Are you using -I with a system include? Does the issue not repro with 1.21.6?

babaoglu53 commented 2 weeks ago

The problem persists with both of them. Also the Log Diagnostics command outputs is as follows:

@babaoglu53 I think gcc 5.4 was released in 2016, but your settings use gnu++23, which may require g++ 12 or newer. That might not be the issue though.

Can you try replacing "/data/user1/projects/test/**" with

"/data/user1/projects/test/newapp",
"/data/user1/projects/test/include"

or whatever other include directories you need?

It looks like something is causing the resolving of "**" in your includePath to fail, possibly due to a database issue.

Can you try doing a Reset IntelliSense Database after setting C_Cpp.loggingLevel to "Debug" and see if the "C/C++" window shows tag parsing messages or if there are database errors/failures?

sean-mcmanus commented 2 weeks ago

Also, you may want to confirm the database file /home/user1/.cache/vscode-cpptools/b21412dcab1fff106533714f9fb12a21/.browse.VC.db has write permissions.

babaoglu53 commented 2 weeks ago

I think the problem was .cache. I deleted and reinstalled everything related to .vscode-server and .cache on the remote server. Now it works as before. Thank you very much for your help.
