I can't jump to GoToDefinitionElseDeclaration in cpp with YouCompleteMe [https://github.com/ycm-core/YouCompleteMe/issues/4085] and my os system is centos 8, It looks like clangd is choking on compiler flags and unable to read them and instantiate the front end.

Could you find any cue from the log?
Thanks!@sam-mccall

The problem is clang -mfpmath=both , which clang doesn't recognize and treats as a fatal error.

You can remove this from your compile flags either in your build system or by adding a clangd config file: https://clangd.llvm.org/config#remove

It's unfortunate that we're not managing to report this in some discoverable way.
(In this case, we fail to create the target info => no preamble => no preambledata => diags just get thrown away)

Filed #1408 for the lack of error reporting.

Unfortunately I'm not sure there's much else to do here, it's hard to know which completely unknown flags are critical.

If -mfpmath=both is an important flag (GCC still says it is "experimental") you can consider requesting clang support it in llvm/llvm-project.

[clangd] Log diagnostics if we failed to create a preamble.

Really we want these to be shown to the client, but the path to do so involves
storing them in

Bandaid for clangd/clangd#1408
See clangd/clangd#1399 for motivation
