It seems this xpc.h file is located in the macOS sdk. The derivation of which is created here: https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/darwin/apple-sdk/default.nix

It looks like the derivation depended on is also in the linked file: apple-lib-xpc

Running into the same issue. Here's my diagnostic output:

  • system: "x86_64-darwin"
  • host os: Darwin 18.5.0, macOS 10.14.4
  • multi-user?: no
  • sandbox: no
  • version: nix-env (Nix) 2.2.1
  • channels: "nixpkgs-19.09pre173720.d73f16d6767"
  • nixpkgs: /Users/e/.nix-defexpr/channels/nixpkgs

I tried working around it by not building the broken target. Here's a post I made on discourse about it.

Looks like that linked apple-sdk package is the macOS 10.10 SDK? That's rather old, it should be updated to a more recent SDK. That said, it looks like there's XPC APIs dating back to macOS 10.7, so maybe header paths changed?

lilyball picture lilyball on 10 Apr 2019

On my system the xpc header is now at:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/xpc/xpc.h

sheeldotme picture sheeldotme on 10 Apr 2019

Likewise for mine: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/xpc/xpc.h.

ekmecic picture ekmecic on 10 Apr 2019

In the darwin.apple_sdk derivation the path is /nix/store/hwzi8c5fcvrkcq6h9hinlfn0b43lzimd-MacOS_SDK-10.10-dev/include/xpc/xpc.h. As long as /nix/store/hwzi8c5fcvrkcq6h9hinlfn0b43lzimd-MacOS_SDK-10.10-dev/include is being set as an include path for clang then the #include <xpc/xpc.h> should work.

FWIW when I try on my machine I get a completely different error right off the bat at 0%:

This is true both with a fairly recent nixpkgs-unstable channel, as well as yesterday's nixpkgs master.

@lilyball, @ekmecic and I are both on nix-env (Nix) 2.2.1, maybe this accounts for the differences we see?

sheeldotme picture sheeldotme on 10 Apr 2019

@sheeldotme Unless Nix 2.2.1 changes the include paths that clang uses, I'm not sure how that would be relevant. Not sure why you're on 2.2.1 and I'm only on 2.2 though; I only see Nix-2.2 in the latest nixpkgs master.

lilyball picture lilyball on 10 Apr 2019

@lilyball my nix install is fresh from the website. They mention 2.2.1 as the latest version there. I'll take a look at the clang include paths when I have access to my machine later today.

ekmecic picture ekmecic on 10 Apr 2019

Interesting, I wonder why it's not available in nixpkgs?

As for the error I get, it looks like xray_fdr_logging.h is trying to use a type that hasn't been defined yet, and then xray_fdr_logging.cc has a block that looks like

#if __MACH__
#include <mach/clock.h>
#include <mach/mach.h>
enum clockid_t {
    CLOCK_MONOTONIC = REALTIME_CLOCK,
    CLOCK_REALTIME = REALTIME_CLOCK
};

int clock_gettime(clockid_t clock_id, struct timespec *ts) {
    …
}
#endif

Given that this is defined in the .cc for #if __MACH__ that suggests this expected to be defined already on non-Darwin platforms, and therefore not expected to be defined on Darwin, meaning xray_fdr_logging.h should fail to compile always. Which means I have no idea why you're not getting this same error.

lilyball picture lilyball on 10 Apr 2019

@lilyball I can can reproduce your errors when I run nix-env -i nixpkgs.llvmPackages_8.compiler-rt.
If I run nix-env -i nixpkgs.llvmPackages_8.clang I don't get those particular errors..

sheeldotme picture sheeldotme on 10 Apr 2019

I was just using nix-env -iA nixpkgs.clang_8. Using nix-env -i nixpkgs.llvmPackages_8.clang still gives me the same errors though.

Now I'm wondering if somehow you have a substitute available for compiler-rt that isn't available for me, though I can't think of why that would be.

lilyball picture lilyball on 10 Apr 2019

Would that reflect in different hashes somewhere we could check for?

sheeldotme picture sheeldotme on 11 Apr 2019

I think substitutes have the same hash, but if you had a substitute available then requesting installation of compiler-rt directly should still get you the substitute (unless the attribute for compiler-rt you listed is not the same as what clang_8 uses). But I don't know enough about Nix to talk about this definitively.

lilyball picture lilyball on 11 Apr 2019

I'm in the same boat! @matthewbauer is there something we can do to help you resolve this?

Interesting, on a different macOS machine I get the same error as @lilyball.
