@Jamlee I see, in your own config you are missing cpp language support. The vscode-builtin-cpp plugin only contributes textmate-grammars (syntax highlighting), and some snippets but no actual integration with a cpp language server.

In our theia-cpp and theia-full images we also include the @theia/cpp extension which provides language features:

https://github.com/theia-ide/theia-apps/blob/a9eefd93bd9c465d60cb812f1f1c9e8d8cbd43dc/theia-cpp-docker/latest.package.json#L20-L21

You may also include @theia/cpp-debug for debug support if you like :smiley:

[Jamlee]

it worked for me.

in addtional, i need install clangd:

sudo apt-get install clangd-9

@vince-fugnitto Thanks
