clangd is installed with requirement for newer glibc than existing clangd on system

[Chaz6]

Problem description

When installing support for clangd, instead of using the system clangd, a new clangd installation is downloaded which requires a newer libc than is available on the system, so attempting to use it will fail. I was able to workaround this by deleting the folder ~/.local/share/nvim/lsp_servers/clangd/clangd then restarting neovim. Please note the contents of LspInfo are shown after implementing the workaround.

Neovim version (>= 0.6)

NVIM v0.7.0-dev+1192-g8ed9c8448
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system/version

Centos 7.9.2009 (Core)

I've recently downloaded the latest plugin version of both nvim-lsp-installer and nvim-lspconfig

• Yes

Affected language servers

clangd

Steps to reproduce

1. Install clangd using :LspInstallInfo
2. Open a *.c file and attempt to use the clangd lsp.

Actual behavior

[ERROR][2022-03-06 15:57:57] .../vim/lsp/rpc.lua:420 "rpc" "clangd" "stderr" "clangd: /lib64/libc.so.6: version GLIBC_2.18' not found (required by clangd)\n"`

Expected behavior

If clangd is already available on the system, the installer should use that instead of downloading a fresh copy that is broken on the system.

I found this: clangd/clangd#722 (comment). This doesn't seem like anything that can be fixed here - maybe there could be a check for which glibc version is installed to make sure it's >= 2.18.

If clangd is already available on the system, the installer should use that instead of downloading a fresh copy that is broken on the system.

I'd recommend simply not managing clangd via nvim-lsp-installer instead. You :LspUninstall clangd and then make sure you set up clangd directly via lspconfig somewhere in your config:

lspconfig.clangd.setup {}
