Can't use Intellisense of C/C++ extension

[GaoPeng415]

I have deploy code-server on my ubuntu server, and it can successfully compile, debug or run C++ code. But the problem is that the syntax highlight, commands, variable, properties... auto complete, publish diagnostics, and code action from C/C++ entension didn't work.

What I want

Here is the screenshots in my local laptop that show what i want.
the word "vector" is green

it suggests me that what i should type

when i make some mistake it will remind me

But these three things don't happen when I use code-server in my server

What I want is the code-server could act consistently with my local vscode.

What I've Tried

I have followed a lot of guidence on the Internet, and also try to ask GPT for help. But all failed. During trail I was aware of that the keypoint is "Intellisense" from "C/C++"

I have followed the guidence on https://code.visualstudio.com/docs/cpp/configure-intellisense. it teaches me to use ">C/C++: Select Intellisense Configuration", and it really work on my local vscode -- after click this
, it will show up
, which is consistent with the guidence.
But when I do this on my code-server, it falied to pop up the follow choices, it just do nothing after i click the ">C/C++: Select Intellisense Configuration".

If anything I've explained is unclear, please don't hesitate to ask me right away.
Thankyou for your help! =)

everytime when I reload the code-server, it shows this warning. I think it might be where the problem come from?

Yeah this extension is not licensed to be used in open-source builds of VS Code, unfortunately. It can only be used in the official Microsoft-provided builds of VS Code.

You might have luck with an alternative, I have not tried these but some users on the VSCodium repository have suggestions:

• C# extension's debugging does not work 0x89720010 VSCodium/vscodium#82 (comment)
• Microsoft Restricts ms-vscode.cpptools on Non-Official VS Code Versions – What Should I Use on VSCodium? VSCodium/vscodium#2329 (comment)
• Open source alternative for the vscode cpptools VSCodium/vscodium#1971
• FOSS/Non MS intellisence extensions? or dropping VSCodium VSCodium/vscodium#1278 (comment)

Thank you for your help!

However, I'm confused about how to use VSCodium as an alternative. Does this mean I can simply replace 'VSCode' with 'VSCodium' in my current code-server setup? Or should I completely abandon code-server and switch to VSCodium with its own remote development components (something similar to code-server)?

I tried the former, but I can't find any tutoria or issue or discussion about "code-server with vscodium". Or dose this path require me to completely build code-server from scratch without exist guidance？

I also search for the latter, but I also failed to find anything related.

Could you please give me some advice on how to use VSCodium to set up a remote development environment? using code-server or any other available method.😥

[code-asher]

Oh sorry, I did not mean to imply you should use VSCodium instead of or in conjunction with code-server. The only takeaway here is because VSCodium is also an open-source build of VS Code, the advice there for extensions often also works for code-server.

VSCodium is based on Electron, so it is a replacement for desktop VS Code, but it is not a replacement for code-server which uses the web version of VS Code. So if you need VS Code in the browser, keep using code-server.

[code-asher]

Note that you can actually run official VS Code web in the browser as well with code serve-web, so you could try that. But, it will be missing the various patches we add in code-server: https://github.com/coder/code-server/blob/main/docs/FAQ.md#whats-the-difference-between-code-server-and-github-codespaces (the section says Codespaces but it applies to self-hosted as well).

Thank you very much!

I use the extension pack on https://open-vsx.org/extension/KylinIdeTeam/kylin-cpp-pack and tackled my problem successfully.

As you mentioned, advices for extensions exactly work for code-server.
