pkgsCross.aarch64-embedded.llvmPackages_16.stdenv.mkDerivation failure

benjaminmordaunt commented 1 year ago

Steps To Reproduce

Steps to reproduce the behaviour:

Create a default.nix that tries to use cross LLVM 16 for aarch64:

{
pkgs ? import (fetchTarball {
url = "https://github.com/NixOS/nixpkgs/archive/refs/tags/23.05.tar.gz";
}) {}
}:
pkgs.pkgsCross.aarch64-embedded.llvmPackages_16.stdenv.mkDerivation rec {
# ...
}

Build log

CMake Error at /nix/store/x27c0x6982aj1ycrywlr7pl7piz3cqjj-cmake-3.25.3/share/cmake-3.25/Modules/CMakeTestCCompiler.cmake:70 (message):

  It fails with the following output:

Additional context

Seems that it cannot find ld.lld?

Reproducer

pkgs.pkgsCross.aarch64-embedded.hello.override { stdenv = pkgs.pkgsCross.aarch64-embedded.llvmPackages_16.stdenv; }

with --keep-failed config.log shows

clang-16: error: unable to execute command: Executable "ld.lld" doesn't exist!
clang-16: error: ld.lld command failed with exit code 1 (use -v to see invocation)

{ pkgs ? import ./. { }, }:

let
  lStdenv = pkgs.pkgsCross.aarch64-embedded.llvmPackages_16.stdenv;
  llvmStdenvWithBintools = pkgs.overrideCC lStdenv (lStdenv.cc.override {
    bintools = pkgs.pkgsCross.aarch64-embedded.buildPackages.llvmPackages_16.bintools;
  });
in
pkgs.pkgsCross.aarch64-embedded.hello.override { stdenv = llvmStdenvWithBintools; }

Using llvm bintools gets us ld.lld.

the build still fails with a unrelated error lib/getprogname.c:287:4: error: "getprogname module not ported to this OS"
