Some dependencies supposed to be skipped in the cross build, along with
not using the gold linker. But in https://github.com/NixOS/nix/pull/6538
this was accidentally not preserved.
Also since https://github.com/NixOS/nix/pull/6538 we saw some new
aarch64-linux static build failures. This is a first attempt to try to
fix those failures. If this is not sufficient, there are other things we
can try next.
It is independent of SourceExprCommand, which is about parsing
installables, except for the fact that parsing installables is one of
the many things influenced by read-only mode.
- `nixpkgsFor` does all of native, static, cross, and the different stdenvs.
- The main Nix derivation is no longer duplicated for static.
- DRY nixpkgs.lib and lib.genAttrs calls.
If this documentation is inaccurate in any way please do not hesitate to suggest corrections.
My understanding of this function is strictly from reading the source code and some limited experience implementing fetchers.
We are looking for *$ because it indicate that it was constructed with a new but
not release. De-referencing shallow copy so deleting as whole might create
dangling pointer that's why we move it so we delete a empty containers + the
nice perf boost.
For static builds, we need to propagate all the static library
dependencies to the link of the program. E.g. if libstore-tests-exe
depends on libnixstore-tests, and libnixstore-tests depends on
libstore, then libstore-tests-exe needs to link against libstore.

- Refer to current version in readme
- Split into flakes and non-flakes section
- Change order to move nix-build to the end, since people often start
with it in the beginning.
- Use proper "Note" syntax
- Add notes about editor integration
- Move information about target platforms and stdenvs into separate
sections

Adding a test to ensure there is no regression.
The tests that are split out of `tests/build.sh` are ones that don't yet
work with CA derivation. I have not yet evaluated whether they should or
not.
This behavior, reported missing in issue #4661, already got fixed in
PR #4818, but didn't get a test case then.
Nixpkgs on aarch64-linux is currently stuck on GCC 9
(https://github.com/NixOS/nixpkgs/issues/208412) and using gcc11Stdenv
doesn't work either.
So use c++2a instead of c++20 for now. Unfortunately this means we
can't use some C++20 features for now (like std::span).
Descriptions for commandline flags may not include newlines and should
be rather short for display in a shell. Truncate the description string
of a flag on '\n' or '.' to and add an ellipsis if needed.
XDG Base Directory is a standard for locations for storing various
files. Nix has a few files which seem to fit in the standard, but
currently use a custom location directly in the user's ~, polluting
it:
- ~/.nix-profile
- ~/.nix-defexpr
- ~/.nix-channels
This commit adds a config option (use-xdg-base-directories) to follow
the XDG spec and instead use the following locations:
- $XDG_STATE_HOME/nix/profile
- $XDG_STATE_HOME/nix/defexpr
- $XDG_STATE_HOME/nix/channels
If $XDG_STATE_HOME is not set, it is assumed to be ~/.local/state.
