vasilito af03420bcc libpng, zsh: two more GCC 14+ strictness regressions
libpng
  contrib/libtests/pngvalid.c calls feenableexcept(), a glibc extension
  relibc does not provide, and GCC 14+ makes the implicit declaration an
  error. It is a test program, so build it the way AGENTS.md
  § CONVENTIONS already prescribes for cross builds -- '--disable-tests'.
  The library is unaffected; only check_PROGRAMS is skipped, and those
  binaries cannot run on the build host regardless.

zsh
  zsh 5.9 probes for the termcap symbol arrays with
      char **test = boolcodes; puts(*test);
  and ncurses declares boolcodes as 'const char * const *'. GCC 14
  promoted -Wincompatible-pointer-types to an error, so the probe stopped
  compiling, configure concluded boolcodes=no, HAVE_BOOLCODES was left
  undefined, and Src/Modules/termcap.c fell back to defining its own
  array -- colliding with the header:
      termcap.c:45: error: conflicting types for 'boolcodes'
  The probe uses a bare shell variable, not an ac_cv_ cache entry, so
  there is nothing to override; restoring the pre-GCC-14 severity is what
  lets it reach the right answer. Scoped to this recipe so the rest of the
  tree keeps the stricter default.

Both cook clean.

Zsh on Redox

Production recipe for Zsh 5.9 on Red Bear OS / Redox.

Status

  • Builds: yes
  • Runtime: basic shell works; times builtin is a no-op stub
  • Blockers: times() not yet in relibc; getrusage() present but returns zeroed data (microkernel design)

Patch Summary

File Change Reason
configure.ac Remove getrusage from AC_CHECK_FUNCS Historical: relibc now has getrusage (returns zeroed data)
Src/builtin.c Stub bin_times() times() unavailable in relibc
Src/Builtins/rlimits.c Disable set_resinfo() / free_resinfo() These depend on getrusage()

Configure Flags

  • --disable-gdbm — avoid GNU dbm dependency
  • --disable-pcre — avoid PCRE dependency
  • --disable-cap — avoid POSIX capabilities dependency
  • zsh_cv_sys_elf=no — skip ELF detection (not applicable on Redox)

Dependencies

  • ncursesw — wide-character terminal library

Install Targets

Zsh uses non-standard install targets:

make install.bin install.modules install.fns DESTDIR="${COOKBOOK_STAGE}"

Configuration Files

The recipe installs Manjaro-inspired system-wide zsh configuration:

File Purpose
/etc/zsh/zshenv Environment variables for all zsh shells
/etc/zsh/zprofile Login shell profile (sources /etc/profile for compatibility)
/etc/zsh/zshrc Interactive shell config: history, completion, colors, prompt, aliases
/etc/skel/.zshrc Template for new users
/etc/skel/.zprofile Template for new users (login shell)

Features (Manjaro-style)

  • Colored prompt: green for user, red for root, with hostname and working directory
  • Right-side prompt: shows exit code on error
  • Tab completion: with menu selection, approximate matching, and colorized listings
  • History: shared across sessions, ignores duplicates and leading-space entries
  • Aliases: ls, ll, la, grep, cp, mv, rm with color and safety flags
  • Convenience: AUTO_CD, CORRECT, NO_BEEP
  • Optional plugins: zsh-syntax-highlighting, zsh-autosuggestions (loaded if available)

Future Work

  • Re-enable times builtin when relibc gains times() support
  • Re-enable resource-limit info getrusage is now available (returns zeroed data)
  • Evaluate enabling gdbm, pcre, or cap if those libraries are ported
  • Package zsh-syntax-highlighting and zsh-autosuggestions plugins
