imenu-unavailable-error: imenu unavailable: "No items suitable for an index found in this buffer"

[jason--liu]

In lsp-mode, when I try to invoke lsp-ui-imenu，it reports imenu unavailable: "No items suitable for an index found in this buffer" I'm not very sure what it means, but from the picture below, we can see lsp-ui can display headerline, so I think there have index, Am I right? So, what is the reason of the error and how to make lsp-ui-imenu work. Thanks.

Are you using clangd?

Are you using clangd?

YES, is that related?

[jason--liu]

@lebensterben It seems that not related to clangd, because I just switched to ccls, it still has the same problem.

See the project setup section.

[jason--liu]

I've read it. The compile_commands.json is already in the project

[lebensterben]

not able to reproduce the issue.

[jason--liu]

Maybe I should describe it more clearly. The first file opened after opening spacemacs, the imenu-list displays normally. However, when I jump to other functions and this function is in other files, this problem occurs.

[lebensterben]

Is that file also in the same project?

[jason--liu]

yes, in the same project
