02:25 <levdub> I have been reinstalling nix on my mac trying to fix some issues. Now my ~/.nix-profile is a dangling symlink. /nix/var/nix/profiles/per-user/lev/profile does not exist. this seems pretty bad.. how would this happen?

11:28 <gchristensen> levdub: that happens if you haven't installed anything yet

14:28 <patrol02> Hello!

14:31 <patrol02> My `cc --version` shows `Apple LLVM version 10.0.1 (clang-1001.0.46.4)`, but when build with GHC (installed with Nix) it seems to be using `clang version 7.1.0 (tags/RELEASE_710/final)`. And then it errors out. What would be a way to tell it to use `clang` that is available and not the older version that pops up somehow?

14:41 <patrol02> When I use `binutils` it tries to build, but produces tons of warnings like `was built for newer OSX version (10.14) than being linked (10.10)`. But I am using `10.14`, not `10.10`.

17:57 <LnL> nix doesn't use what's installed on your system, that's kind of the point

17:59 <LnL> but we have multiple versions of llvm/clang in nixpkgs which you could use instead of the default

18:00 <levdub> gchristensen: my (poor) understanding is that ~/.nix-profile should contain some SSL certs that are needed in order to curl and install things

18:01 <levdub> without them, I get an issue like "error (ignored): unable to download 'https://cache.nixos.org/jl50iznh81znnf2jw9fy32hs9m0s577d.narinfo': Problem with the SSL CA cert (path? access rights?) (77)" and "error: unexpected end-of-file"

18:58 <LnL> for a single-user install, yes

19:14 <levdub> LnL: do you mean that the certs are stored there for single-user install but elsewhere for multi-user?

19:19 <LnL> indeed, it separates per-user software from the system profile (where nix is installed)

19:29 <levdub> yeah that makes sense. where would the certs be in multi-user mode? I am having a fair bit of trouble getting started with nix-darwin

19:30 <levdub> during install, theres a step that prints "generating SSL certs" or something similar, but it doesnt show where they are

21:47 <patrol02> I see the point in not using defaults, however the compiler that is on Nix seems to be way behind from the default Mac OS which causes some problems :(

22:45 <LnL> it's one version behind the last llvm release which is pretty normal and you can configure your build to use clang8 if you want

22:46 <LnL> also I highly doubt that the actual problem
