The command
```
nix-build -A tests.trivial-builders.references --show-trace
```
fails eval with
```
in job ‘nixpkgs.tests.trivial-builders.references’:
error: The option `meta.description' does not exist. Definition values:
- In `makeTest parameters': "Run the Nixpkgs trivial builders tests"
```
because `meta.description` and `meta.license` are not valid for
`nixosTest`s (they are valid for `mkDerivation` of course).
This has been causing Hydra eval failures:
https://hydra.nixos.org/jobset/nixos/pr-209870-gcc-external-bootstrap#tabs-errors
Let's fix eval by removing these attributes.
Without this change $target-cpp is used unwrapped and is missing
standard header search paths among other things).
Example failure:
$ nix build -f. -L pkgsStatic.netbsd.compat

This commit adds basic support for tree-sitter in the emacs build,
such that (if the user opts into tree-sitter support), tree-sitter
will be enabled and binary library files for tree-sitter can be
included in the `lib` directory of packages passed to
`emacsWithPackages`. The libraries will be aggregated and included in
treesit-extra-load-path.
The previous pattern for this in the community was to add tree-sitter
libaries by patching emacs's `RUNPATH` with `patchelf` in a post-fixup
phase. However, this has the substantial drawback that two different
emacs installations with different lists of available tree-sitter
libraries must be entirely separate builds. By supplying the
tree-sitter libraries in the wrapping layer of `emacsWithpackages`, it
becomes possible to share a single, more-cacheable "core emacs".
This support defaults to "on" only in emacs 29 and up, since previous
versions do not support tree-sitter out of the box.
`fixupPhase` move `$out/man` to `$out/share/man`. So the information of their location in the dune-project file is outdated which breaks dependencies on packages ( `(package foo)`).
Sometimes it's more ergonomic to set up the build environment in
hooks, to add to the default behaviour rather than replacing it. It's
very surprising that the fetcher works fine with a custom unpackPhase,
but not with custom preUnpack or postUnpack.
Packages that use preUnpack or postUnpack and Cargo FODs seem to be
very rare. I searched Nixpkgs for files containing one of
"cargoHash", "cargoDeps", and "cargoSha256", and one of "preUnpack" or
"postUnpack", and only found two such packages:
python3.pkgs.tokenizers and rustdesk. Neither of their Cargo FOD
hashes are affected by this change. So if that's any indication,
we're unlikely to be breaking many out-of-tree hashes with these
changes either.
Currently, separate-debug-info adds a debug output, and the build fail when it is
not created. the output is only created when at least one elf file is
stripped.
As a result, adding separateDebugInfo = true on a lib will break the
static build (unless the lib also contains an executable). In order to
not have to remember to add an exception every time, let's just create
the debug output unconditionally.
(and gitiles)
This allows fetching a patch from servers that return them
base64-encoded, like this:
fetchpatch {
name = "gcc.patch";
url = "f37ae3b1a8^!?format=TEXT";
decode = "base64 -d";
sha256 = "11j1bqz2p8xrfzgfrylgdvmqs45489c4ckl7l0ra1dpfgbqy94a8";
}
Fixes linker errors while building build.rs where it tries to link libiconv but cannot find it.
Rust executable build for Darwin need libiconv, and indeed buildInputs already has this case handled.
So why is another change needed? Suppose we are cross compiling from Darwin (the build platform) to something else, and the package has a build.rs build script.
The build script is built for the build platform (Darwin) and is also a regular Rust executable, needing libiconv, but due to cross compilation (and strict deps) we need an extra nativeBuildInput.
