I am using neovim and clangd. I set up neovim using nvchad and clangd exactly according to this video (https://www.youtube.com/watch?v=lsFoZIg-oDs) many months ago mainly for the purpose of autocompletion. Then I did not use c++ for a while and now I have problem with clangd recognizing standard c++ headder files. The autocompletions works. The only real change that happened in between on my system must have been the latest updates of macOS.

I tried to google a lot of things and also look at the clangd troubleshooting. It usually advices to set up a "compile_commands.json" file, but I did not have to do this before and it worked. Also, I tried this solution, but nothing changed.

System information

Output of clangd --version:

Apple clangd version 15.0.0 (clang-1500.3.9.4)
Features: mac+xpc
Platform: x86_64-apple-darwin23.4.0

Editor/LSP plugin:

neovim

Operating system:

macOS Sonoma 14.4.1

Please start by looking at

https://clangd.llvm.org/troubleshooting#cant-find-standard-library-headers-map-stdioh-etc

and

https://clangd.llvm.org/guides/system-headers#query-driver

--query-driver in particular tends to resolve this category of issue.

Thank you very much, this is definitely a progress! I have added the line
cmd = {"clangd", "--query-driver=/usr/bin/clang"}
to one of the configuration files in nvim:

local base = require("plugins.configs.lspconfig")
local on_attach = base.on_attach
local capabilities = base.capabilities

--disable snippets
--capabilities.textDocument.completion.completionItem.snippetSupport = false

local lspconfig = require("lspconfig")

-- fixing some clangd + nvchad bug
lspconfig.clangd.setup({
  on_attach = function(client, bufnr)
    client.server_capabilities.signatureHelpProvider = false
    on_attach(client, bufnr)
  end,
  capabilities = capabilities,
  cmd = {"clangd", "--query-driver=/usr/bin/clang"}
})

This is great, but I would still like to understand why this suddenly happened and why it worked without this line before.

Also I realized on more thing: this solution for some reason messes up the colorscheme -- all the variables are green (in the case of the colorscheme I am using) instead of just white.

If you share verbose logs without --query-driver, that might shed light on this question.

Thank you very much!

It is quite a mess, but here is the log file.

It is quite a mess, but here is the log file.

Unfortunately these logs are incomplete. I'm looking for the full stderr from the server, these seem to include only one line from the server's stderr, and a bunch of client-side logging.

Ok, so the relevant parts of the log are:

I[09:02:47.844] ASTWorker building file /Users/peterzeman/test.cpp version 0 with command clangd fallback
[/Users/peterzeman]
/Library/Developer/CommandLineTools/usr/bin/clang -resource-dir=/Users/peterzeman/.local/share/nvim/mason/packages/clangd/clangd_18.1.3/lib/clang/18 -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -- /Users/peterzeman/test.cpp

In the absence of --query-driver, what clangd has to go on to try to find standard library headers is basically the compiler path from the file's compile command, /Library/Developer/CommandLineTools/usr/bin/clang.

And then:

V[09:02:47.849] Driver produced command: cc1 -cc1 -triple x86_64-apple-macosx14.0.0 -Wundef-prefix=TARGET_OS_ -Werror=undef-prefix -Wdeprecated-objc-isa-usage -Werror=deprecated-objc-isa-usage -fsyntax-only -disable-free -clear-ast-before-backend -disable-llvm-verifier -discard-value-names -main-file-name test.cpp -mrelocation-model pic -pic-level 2 -mframe-pointer=all -ffp-contract=on -fno-rounding-math -funwind-tables=2 -target-sdk-version=14.4 -fcompatibility-qualified-id-block-type-checking -fvisibility-inlines-hidden-static-local-var -fbuiltin-headers-in-system-modules -fdefine-target-os-macros -target-cpu penryn -tune-cpu generic -debugger-tuning=lldb -fdebug-compilation-dir=/Users/peterzeman -target-linker-version 820.1 -fcoverage-compilation-dir=/Users/peterzeman -resource-dir /Users/peterzeman/.local/share/nvim/mason/packages/clangd/clangd_18.1.3/lib/clang/18 -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -internal-isystem /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1 -internal-isystem /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/local/include -internal-isystem /Users/peterzeman/.local/share/nvim/mason/packages/clangd/clangd_18.1.3/lib/clang/18/include -internal-externc-isystem /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include -fdeprecated-macro -ferror-limit 19 -stack-protector 1 -fblocks -fencode-extended-block-signature -fregister-global-dtors-with-atexit -fgnuc-version=4.2.1 -fskip-odr-check-in-gmf -fcxx-exceptions -fexceptions -fmax-type-align=16 -no-round-trip-args -D__GCC_HAVE_DWARF2_CFI_ASM=1 -x c++ /Users/peterzeman/test.cpp

which tells us that, based on this compiler path, clangd came up with the following system include directories:

-internal-isystem /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1
-internal-isystem /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/local/include
-internal-isystem /Users/peterzeman/.local/share/nvim/mason/packages/clangd/clangd_18.1.3/lib/clang/18/include
-internal-externc-isystem /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include

The path for C++ standard library includes, in particular, is /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1. As you can see, it's expressed relative to the path containing the compiler executable, /Library/Developer/CommandLineTools/usr/bin.

Presumably, if you're getting unresolved include errors, this path (/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1) does not exist?

Presumably, if you're getting unresolved include errors, this path (/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1) does not exist?

Ok, I see the problem. The path exists, but for some reason it does not contain the include files that I am looking for only some that I am absolutely not familiar with:

__cxx_version     __cxxabi_config.h cxxabi.h

__bit:
bit_cast.h

__charconv:
chars_format.h      from_chars_result.h to_chars_result.h

__compare:
common_comparison_category.h compare_three_way_result.h   ordering.h                   three_way_comparable.h
compare_three_way.h          is_eq.h                      synth_three_way.h

__concepts:
arithmetic.h            common_reference_with.h copyable.h              equality_comparable.h   regular.h               swappable.h
assignable.h            common_with.h           derived_from.h          invocable.h             relation.h              totally_ordered.h
boolean_testable.h      constructible.h         destructible.h          movable.h               same_as.h
class_or_enum.h         convertible_to.h        different_from.h        predicate.h             semiregular.h

__format:
format_arg.h             format_context.h         format_string.h          formatter_bool.h         formatter_integer.h      formatter_string.h
format_args.h            format_fwd.h             formatter.h              formatter_char.h         formatter_integral.h     parser_std_format_spec.h

__functional:
bind_back.h compose.h

__iterator:
unreachable_sentinel.h

__ranges:
counted.h       iota_view.h     join_view.h     range_adaptor.h reverse_view.h  single_view.h   take_view.h

__utility:
decay_copy.h

The path for C++ standard library includes, in particular, is /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1. As you can see, it's expressed relative to the path containing the compiler executable, /Library/Developer/CommandLineTools/usr/bin.

Ok, so I found out that the path for C++ standard library includes actually is
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1
