#!/bin/sh
# Build script for Lua 5.4 (plain uname-keyed Makefile - NOT autotools).
#
# Lua's src/Makefile only has a "guess"/named-platform target dispatch (no
# dedicated Hammerhead/illumos entry) and its "posix"/"solaris" targets only
# ever produce a STATIC liblua.a - there is no shared-library target at all
# upstream, on any platform. So this build.sh does two passes:
# 1. `gmake posix` - the generic POSIX target (illumos has no dedicated
# target; "solaris"/"SunOS" exists but drags in Solaris-specific
# readline assumptions we don't want) - gives us liblua.a + lua/luac
# binaries, and validates the objects build cleanly.
# 2. Manually recompile the library objects -fPIC and link them into a
# real liblua.so.5.4 - conky/neovim need a *shared* liblua, which
# upstream never ships, so this has to be done by hand.
# Finally we write a lua.pc by hand (upstream Lua ships NO pkg-config file
# at all) so consumers (conky, neovim) can find it via pkg-config.

# --- Pass 2: shared liblua.so.5.4 ---
# CORE_O/LIB_O objects were already compiled -fPIC above (MYCFLAGS carried
# -fPIC into SYSCFLAGS via MYCFLAGS), so relink into a shared object rather
# than recompiling. lua.o/luac.o are excluded (those are the standalone
# interpreter/compiler mains, not part of the library).
# NOTE: coral invokes build.sh via `zsh script.sh` (not `sh script.sh`), so
# the shebang is not honored and zsh's default (no word-splitting on
# unquoted variable expansion) applies - an "$CORE_O $LIB_O" variable
# reference collapses to a single argument and breaks the link. Inline the
# object list literally (plain script tokens, not a variable) to sidestep
# the shell-dependent splitting behavior entirely.
