local/sources/libc is libc 0.2.189 with src/unix/redox/mod.rs extended to
expose the waitid surface relibc already implements:
- idtype_t (= c_int, as relibc defines it)
- P_ALL / P_PID / P_PGID
- CLD_EXITED / KILLED / DUMPED / TRAPPED / STOPPED / CONTINUED
- extern fn waitid(idtype_t, id_t, *mut siginfo_t, c_int) -> c_int
All of it is real in relibc -- src/header/sys_wait/mod.rs defines the
types and constants, and `nm libc.a` shows `T waitid` -- but the libc
crate's Redox bindings never exposed any of it, and still do not as of
0.2.189. Any crate calling waitid therefore cannot build for
x86_64-unknown-redox:
error[E0531]: cannot find unit struct, unit variant or constant
`CLD_EXITED` in crate `libc`
which breaks nix, and through it ctrlc and rustc's bootstrap tooling --
the last thing blocking rust-native.
Values and types come from relibc, not from Linux. Every non-Redox target
is byte-for-byte upstream 0.2.189, so host builds are unaffected. Wired
into the rust workspace via [patch.crates-io]; the fork type-checks for
x86_64-unknown-redox.
Upstream-reportable: this gap belongs in the libc crate.
gcc13
The host compiler is now GCC 16, which defaults to C++20
(__cplusplus 202002L). C++20 changed u8"" literals from const char[] to
const char8_t[], and GCC 13's libcody -- its module mapper -- uses them
throughout, so the build collapsed with ~100 diagnostics like
error: invalid conversion from 'const char8_t*' to 'const char*'
in libcody/{buffer,client,server}.cc. GCC 13's sources are C++17; build
them at that standard. Not a workaround -- it is the dialect this
release was written against.
rust / rust-native
nix 0.30.1 is incompatible with the resolved libc 0.2.178: it declares
type SaFlags_t = libc::c_ulong while libc now has sigaction.sa_flags and
the SA_* constants as c_int, so rustc's bootstrap tooling failed with
error[E0308]: expected `u64`, found `i32` nix/src/macros.rs:72
error[E0308]: expected `i32`, found `u64` nix/src/sys/signal.rs:808
nix 0.31 fixed it by flipping the default to c_int. ctrlc moves itself
(3.5 requires nix "0.31"), but in-tree miri pinned 0.30.1 and kept the
broken version in the graph, so both are moved forward -- update and
adapt rather than pinning libc back, per the
Most-recent-upstream-when-building rule. Both crates were already in the
offline registry cache.
These surfaced only because gcc-native/rust-native were restored to the
config; neither had been building.
Comprehensive fix — not a fallback. Each recipe now has explicit
[package] section with name and version. Version inference:
- Git-source recipes without rev/branch: '0.1.0' (Red Bear convention)
- Tar/git recipes with version in URL or dir name: extracted version
- Sysroot-copy recipes: matched to toolchain version
Affected: 250+ recipes across all categories (core, libs, dev, system,
kde, qt, drivers, gpu, drm, kernel, userspace, etc.) Every recipe
in the redbear-mini build chain that was missing [package] now has
explicit version metadata. Cookbook can now always determine a version
at packaging time, eliminating 'cannot guess version' failures.
No cookbook fallback hack — the source of truth is recipe metadata.
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)
Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.
Build: make all CONFIG_NAME=redbear-full
