Theia: Go to definition and outline doesn't work in cpp code

[yeonggyulim]

Description

Go to definition and outline work in java, but they don't in cpp code even if I installed cpp and textmate packages. Anyone knows why?

Reproduction Steps

OS and Theia version:
Windows 10
@theia/java : ^0.3.19
@theia/cpp: ^0.3.19
@theia/textmate-grammars: ^0.3.19

Diagnostics:

Do you have the cpp language server installed ? You can find information in the @theia/cpp readme.
Theia uses clangd to enable LSP features for cpp.

I installed clangd through LLVM and make the path in C:\Program Fiels\LLVM\bin.

However, I still see this error and LSP features don't work. Do you know why?

You can try specifying the location of your clangd using the following preference:
https://github.com/theia-ide/theia/blob/e1b5a60f0841f8edf1d8d60d99012e996fc145bc/packages/cpp/src/browser/cpp-preferences.ts#L56

Is this what you mean?

but, how can I compile this to bundle?
there's no tsconfig.json file and it goes away whenever I build with yarn.

I installed @thiea/cpp package and clangd, but I can't figure out what to do next.

@yeonggyulim with clangd installed and the path referenced through the preference, were you able to benefit from cpp language support? (go to definition, hover...)

but, how can I compile this to bundle?
there's no tsconfig.json file and it goes away whenever I build with yarn.

I'm not quite sure what you mean, can you clarify what are you looking to accomplish?

[yeonggyulim]

I found the problem.

It works after downloading clangd.
The problem I was suffering is it works on windows command prompt, but it doesn't with terminal on visual studio code.

Thank you for your help.
