On the Question of Cross-compiler Project

[3038922]

My English is not very good, so I need to use translation software. Thank you very much for your guidance, I have successfully built llvm and ccls.
q1:
The VS CODE console displays the following error message. It's the same as cquery I used before.
I'm a student's competition. I can't see 'main. cpp' in it.Only 'main.hpp.'
Does this cause no index?
[Error - 11:42:19 AM] Request textDocument/codeAction failed. Message: not indexed Code: -32600 [Error - 11:42:19 AM] Request textDocument/documentLink failed. Message: not indexed Code: -32600 [Error - 11:42:19 AM] Request textDocument/documentLink failed. Message: not indexed Code: -32600 [Error - 11:42:19 AM] Request textDocument/foldingRange failed. Message: not indexed Code: -32600 [Error - 11:42:20 AM] Request textDocument/documentSymbol failed. Message: not indexed Code: -32600

Q2:
Lines of Preprocessing code do not darken.

My CCLS configuration:

`

my makefile
Github's code support for makefile is not working. So I use pictures. Sorry.

[MaskRay]

clang++ ... --std=gnu11 "src\system\ncr_font10.c"

You should just use clang, not clang++. You should see the driver error:

error: invalid argument '--std=gnu11' not allowed with 'C++'

Github's code support for makefile is not working. So I use pictures. Sorry.

For fenced code blocks, use makefile to get Makefile syntax highlighting:

 ```makefile

Request textDocument/codeAction failed. Message: not indexed Code: -32600

Please format this code block. not indexed indicates that the file has not been indexed.

Since main.hpp is considered a header, it is not indexed on its own. Imagine there is a main.cpp which includes main.hpp. If you open main.cpp, both main.cpp and main.hpp will be indexed.

I have also implemented a heuristic: if the initial loading has finished, when you open a new header, even if it is included, it will be indexed. For your case, you may close main.hpp and then re-open it (to deliver textDocument/didOpen notification to the ccls server, it'll index it)

// https://github.com/maskray/ccls/blob/master/src/messages/textDocument_did.cc#L54
  // Submit new index request if it is not a header file or there is no
  // pending index request.
  auto [lang, header] = lookupExtension(path);
  if ((lang != LanguageId::Unknown && !header) ||
      !pipeline::pending_index_requests)
    pipeline::Index(path, {}, IndexMode::Normal, false);
  if (header)
    project->IndexRelated(path);

@MaskRay Finally, how to darken precompiled code segments?

In this position he will add a horizontal line.

There is no change in his position here. I use a lot of pretreatment to distinguish each robot. It's very helpful for me to realize the function of color change.
