Clang seems to have problems finding c++ related headers, rdm crashes #1198

Open tuvok opened 6 years ago

tuvok commented 6 years ago

Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

  1. Clone repo: https://github.com/tuvok/spacebrowser/tree/passwordManager
  2. Use cmake to generate compile_commands.json and load them with rc -J
  3. Open PasswordManager.cpp with emacs, somewhere in one of the functions write "gpg." + company-complete
  4. No useful completions show up and rdm is crashed

Expected behavior rdm should provide completions without crashing

Screenshots/Backtrace When I start rdm without additional options, this is the output:

If I start rdm with additional include paths, the output is a bit different, but it still crashes:

Environment (please complete the following information):

I will gladly provide any additional info needed

Sorry about the long delay.

I suppose this problem isn't really limited to spacebrowser.

I think this is related to your clang install and rtags' assumptions about where its central headers are supposed to be installed.

Are you building this clang yourself or getting it from gentoo's package system?

Can you try to let rtags build clang for you?

E.g.

cmake -DRTAGS_BUILD_CLANG=1 ...

There's some more info on this in the readme.

tuvok commented 6 years ago

I'm using clang from gentoo's package system. Is there a way to point rtags to the right headers directory? I'd prefer to use system installed clang if possible.
