`ccls` cannot execute binary file

[MomePP]

Problem description

ccls was installed successfully but when lsp start the process, 'Client 1 quit with exit code 126 and signal 0'

I've try to execute binary directly and it failed to execute.

exec: Exec format error
The file './ccls' is marked as an executable but could not be run by the operating system.

There is no issue while installing the LSP but might be related with build flag.

PS. I've installed llvm stable 13.0.1 from Homebrew

Neovim version (>= 0.6)

NVIM v0.6.1 Build type: Release LuaJIT 2.1.0-beta3

Operating system/version

Darwin 21.3.0 Darwin Kernel Version 21.3.0: root:xnu-8019.80.24~20/RELEASE_ARM64_T8101 arm64

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

Affected language servers

execute ccls directly

Seems to be issue from CMAKE_PREFIX_PATH. I've changed llvm_dir just like the attach screenshot. ccls build macos

And ccls getting back to work as expected after reinstall the LSP.

Hello! Hmm I'm running virtually the same environment but I'm not experiencing any issues. Let's try your suggestion, I see now that the guide suggests appending /lib/cmake to the llvm root path

[williamboman]

@MomePP Does branch ccls-macos-prefix-path fix this?

[MomePP]

@williamboman Yes, it does. I've completely remove ccls and try to switching branch between llvm root path. ccls-macos-prefix-path fixed the issue.
