The Zig standard library had a major restructuring in 0.16.0, primarily around the new Io abstraction. This updates all source files to use the new APIs: - std.process.getEnvVarOwned → b.graph.environ_map.get (build.zig) and std.process.Environ (runtime) - std.fs.cwd() → std.Io.Dir.cwd() - File methods (close, stat, writer, reader) now take io: Io parameter - std.fs.getAppDataDir removed; replaced with manual XDG/platform logic - std.process.execve → std.process.replace - Build module methods (addIncludePath, addCSourceFile, linkSystemLibrary) moved from Compile step to root_module - main() accepts std.process.Init for Io and Environ access Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Any reason you dropped support for glibc and went musl only? |

Yeah, this branch still contains non-sense change for debug and test purposes, I will sort out branch to remove non sense changes and then force push them. |

changed the title
Cross-compilation fixes (Zig 0.16.0 API changes): - Replace std.c.stat with Io.Dir.cwd().statFile - Rename Permissions.unixNew → Permissions.fromMode - Remove unused arena parameter from maybe_install_musl_runtime - Comptime-guard the musl runtime call site on macOS - Guard Permissions.toMode() on Windows (enum, no POSIX mode bits) Process spawning (cross-platform): - Replace std.process.replace with std.process.spawn + child.wait (std.process.replace does not work reliably on macOS arm64) - Unify Windows/Unix code paths via the same spawn+wait pattern CI: - Add Zig 0.16.0 to the cross-build matrix - Add macOS arm64 (macos-14) runner
Passing '-elixir ansi_enabled true' and '-s elixir start_cli' as single argv entries (with embedded spaces) caused the BEAM to hang in __select when spawned via std.process.spawn on macOS. erlexec passes them through to beam.smp as-is, and beam.smp doesn't split space-delimited args. Splitting them into separate argv entries fixes the hang.
