#!/bin/sh
# Build script for imlib2 (autotools, Template A).
# NOTE: imlib2's optional loaders (gif/tiff/webp/heif/jxl/...) are each
# auto-probed via AC_CHECK_LIB/pkg-config in configure.ac - there are no
# --without-<format> flags to pass. Since none of those libs are ported to
# Hammerhead yet, the loaders auto-disable and only png/jpeg (both present)
# get built.
#
# REVISED (Task 1b-3, 2026-07-22): originally built --without-x on the
# assumption that "X11 client apps link libX11 themselves" - WRONG. imlib2's
# X11 support (gated by AC_PATH_XTRA/BUILD_X11) is not just SHM plumbing; it
# ships the imlib_context_set_{display,visual,colormap,drawable}() /
# imlib_render_image_on_drawable*() / imlib_create_image_from_drawable() API
# that feh (wallpaper-setting) and other imlib2 consumers (tint2's
# IMLIB2>=1.4.2 dep) call directly. --without-x drops those symbols entirely,
# so feh failed to link ("undefined reference to imlib_context_set_drawable"
# etc). Enable X11 support instead (needs no explicit flag - AC_PATH_XTRA
# auto-detects libX11 under $PREFIX via the CFLAGS/LDFLAGS -I/-L already
# exported below).

# MANDATORY libtool fix - see Template A comment in DESKTOP_XLIBRE_PHASE1A_PLAN.md.
