It's weird, seems g++ and gcc can be indexed both... |
|
Yes. And it's the running outcome.

Maybe this will help you: #370 |
|

You can install latest |
|
That's weird. Today I started it for the first time with no problem. But when I re-enter neovm it gives me errors, even if I have the latest The first time
Now

Hi @llzzzzoo! My bad for jumpin in late, but can u try compiling this file ( #include <any>
#include <list>
int main() { std::any any{std::list<int>{}}; }with: clang++ -std=gnu++17 test.cpp -vand drop the compiler output here? Just wanna check if it's an issue with library search paths or smth else 🤔 u should see smth kinda like this: FreeBSD clang version 18.1.5 (https://github.com/llvm/llvm-project.git llvmorg-18.1.5-0-g617a15a9eac9)

OK.

Thanks! First off, did u install our config using the install script? Cuz that sets up all the necessary packages for u. If yes, go to 1, otherwise skip to 2.

bufnr = require("lspconfig").util.validate_bufnr(bufnr)

local params = { uri = vim.uri_from_bufnr(bufnr) }
if clangd_client then
clangd_client.request("textDocument/switchSourceHeader", params, function(err, result)
if err then

if not result then

Note Installing anything non-MSVC without a package manager is a nightmare, so I wouldn't even try it unless u really have to. |

Thanks for your reply. I installed this config by your script.
Here is the output.

A general advice is if ur just using C++ u don't need it. But r u using any part of LLVM's compiler infrastructure like LLVM IR or specific compiler/diagnostics options? If not, just uninstall it lol cuz on Windows u usually gotta bootstrap LLVM urself so it knows where ur system headers are and fixes the search path.
u don't need to modify anything lol just copy the code I attached above, and it'll automatically detect ur GCC install. And the file is called |

Thank you so much.

that's expected. since we define this |

How to reproduce the issue
I have the same problem as the link below. I can run the cpp file normally from the terminal, but the compiler still throws an error.
#1366
How can I finish that? Thank you so much.
