You can build (partially) with LLVM toolchain using the useLLVM flag.
This works like so:
nix-build -A hello --arg crossSystem '{ system =
"aarch64-unknown-linux-musl"; useLLVM = true }'
also don’t separate debug info in lldClang
It doesn’t work currently with that setup hook. Missing build-id?
Comments on conflicts:
- llvm: d6f401e1 vs. 469ecc70 - docs for 6 and 7 say the default is
to build all targets, so we should be fine
- some pypi hashes: they were equivalent, just base16 vs. base32
For a long time now, tracing has been broken in Nixpkgs. So when you
have an eval error you would get something like this:
error: while evaluating the attribute 'buildInputs' of the derivation 'hello-2.10' at /home/mbauer/nixpkgs/pkgs/stdenv/generic/make-derivation.nix:185:11:
while evaluating 'chooseDevOutputs' at /home/mbauer/nixpkgs/lib/attrsets.nix:474:22, called from undefined position:
while evaluating 'optionals' at /home/mbauer/nixpkgs/lib/lists.nix:257:5, called from /home/mbauer/nixpkgs/pkgs/stdenv/generic/make-derivation.nix:132:17:
This is coming from how Nix handles string context and how
make-derivation messes with the "name" attribute. This commit should
restore the old behavior so you get a nice line number like:
error: while evaluating the attribute 'buildInputs' of the derivation 'hello-2.10' at /home/mbauer/nixpkgs/pkgs/applications/misc/hello/default.nix:4:3:
while evaluating 'chooseDevOutputs' at /home/mbauer/nixpkgs/lib/attrsets.nix:474:22, called from undefined position:
while evaluating 'optionals' at /home/mbauer/nixpkgs/lib/lists.nix:257:5, called from /home/mbauer/nixpkgs/pkgs/stdenv/generic/make-derivation.nix:132:17:
NOTE: This will still be broken for cross compilation due to the
prefixes we are adding to name.
This behavior ended up breaking the handleEvalIssue functionality by hiding those packages. So something like this:
$ nix-env -iA nixpkgs.zoom-us
would silently fail, without telling the user how to fix it! Regardless, this "bug" should be handled in Nix - not Nixpkgs.
Fixes#38952.
We can't run the checkPhase when build != host, so we may as well make
the checkInputs native.
This signicantly improves the situation of Python packages when enabling
strictDeps.
* add generic x86_32 support
- Add support for i386-i586.
- Add `isx86_32` predicate that can replace most uses of `isi686`.
- `isi686` is reinterpreted to mean "exactly i686 arch, and not say i585 or i386".
- This branch was used to build working i586 kernel running on i586 hardware.
* revert `isi[345]86`, remove dead code
- Remove changes to dead code in `doubles.nix` and `for-meta.nix`.
- Remove `isi[345]86` predicates since other cpu families don't have specific model predicates.
* remove i386-linux since linux not supported on that cpu
Hydra's page showing evaluation errors is about a mile long, showing
buckets of user-friendly errors, like this:
in job ‘seyren.aarch64-linux’:
Package ‘oraclejre-8u191’ in /nix/store/fa9zzkbljkvdavwzirkrr5irg25ymbjl-source/pkgs/development/compilers/oraclejdk/jdk-linux-base.nix:71 has an unfree license (‘unfree’), refusing to evaluate.
a) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.
in job ‘jetbrains.webstorm.x86_64-linux’:
Package ‘webstorm-2018.3.1’ in /nix/store/fa9zzkbljkvdavwzirkrr5irg25ymbjl-source/pkgs/applications/editors/jetbrains/default.nix:230 has an unfree license (‘unfree’), refusing to evaluate.
a) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.
This makes it extremely hard to find actual issues in the output. This
patch set makes the output much more condensed in Hydra:
Failed to evaluate nifticlib-2.0.0: «unsupported»: is not supported on ‘x86_64-apple-darwin’
Failed to evaluate dmd-2.081.2: «unsupported»: is not supported on ‘aarch64-unknown-linux-gnu’

Adds the static overlay that can be used to build Nixpkgs statically.
Can be used like:
nix build pkgsStatic.hello
Not all packages build, as some rely on dynamic linking.
crossOverlays only apply to the packages being built, not the build
packages. It is useful when you don’t care what is used to build your
packages, just what is being built. The idea relies heavily on the
cross compiling infrastructure. Using this implies that we need to
create a cross stdenv.
Some trivial builders use the name attr to choose the exec name
produced. For example nixos-install,
nixos-install = makeProg {
name = "nixos-install";
src = ./nixos-install.sh;
nix = config.nix.package.out;
path = makeBinPath [ nixos-enter ];
};
When cross compiling, this puts the prog in,
/bin/nixos-install-powerpc64le-unknown-linux-gnu
