#!/bin/sh
# Build script for xf86-video-illumosfb (autotools, Template A variant).
#
# Phase 2 Task 3 (M2). This port ships NO pre-generated `configure` - only
# configure.ac/Makefile.am + its own autogen.sh (confirmed via `tar tf` on the
# git-commit-archive tarball). Must run `NOCONFIGURE=1 ./autogen.sh` (which is
# just `autoreconf -v --install` under the hood) before the usual
# libtool/config.sub fix + configure, same shape as base/x11vnc (Task 7a).
#
# configure.ac requires xorg-macros (XORG_MACROS_VERSION/XORG_DEFAULT_OPTIONS)
# at aclocal time. base/util-macros installs xorg-macros.m4 under
# $PREFIX/share/aclocal (/usr/local/share/aclocal), which is NOT on aclocal's
# default search path (/usr/share/aclocal) - export ACLOCAL_PATH so the
# autoreconf inside autogen.sh finds it.
#
# Module install dir: configure.ac defaults --with-xorg-module-dir to
# "$libdir/xorg/modules", but this XLibre build (base/xlibre-xserver-xorg)
# uses a versioned moduledir, $libdir/xorg/modules/xlibre-25 (see that port's
# xorg-server.pc: moduledir=${exec_prefix}/lib/xorg/modules/xlibre-25). The
# driver's own Makefile.am appends "/drivers" to @moduledir@, so pass
# --with-xorg-module-dir="$PREFIX/lib/xorg/modules/xlibre-25" here to land
# illumosfb_drv.so where Xorg's video_drivers_dir actually points.
#
# ABI: illumosfb_driver.c's XF86ModuleVersionInfo uses the SDK's
# ABI_VIDEODRV_VERSION macro directly (no hardcoded ABI number) - building
# against xorg-server.pc's SDK headers means the ABI always matches the
# server it's paired with. No ABI patch expected/needed.
