Describe the bug
The ccls server does not start.

To Reproduce

I'm using the the latest ccls version and the config from the wiki with this minimal vimrc:

vim set nocompatible set runtimepath^=/path/to/coc.nvim filetype plugin indent on syntax on set hidden
When editing a C file I get the following error:
[coc.nvim] Error output from languageserver.ccls: ccls exited with code: null

The issue persists when I try to edit test.c with the following folder layout:
test/test.c
test/.env

[chemzqm]

No idea about the crash of ccls, can't reproduce with stable release of ccls.

[quebin31]

Could be related with MaskRay/ccls #363?

Buildings with clang 8 seems to fix that problem. I've tried manually building the package but I still get the same error.

[sainnhe]

For arch linux users who install ccls from AUR, try to modify build() in PKGBUILD

cmake -H. -Bbuild -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_CXX_COMPILER=clang++

It solves my problem.

Thanks this also solves the problem on my machine. Maybe the issue is Arch-specific?

[sainnhe]

@yhamdoud I don't know, some said it's because clang has been updated to version 8. Maybe people who use other distro will also encounter this problem if they update clang.

[quebin31]

@yhamdoud It doesn't neccesarily is Arch specific, as noted in the issue it's the problem with the default g++ compiler, it triggers Arch because we are on the bleeding-edge of updates.

Also mine. The AUR package have that fixed now.

[chemzqm]

Closing, since it's compile issue of ccls and should be fixed now.
