#!/bin/sh
# Build script for xlibre-xserver (Meson, Template B) — Xvfb-only headless build.
#
# THE crux port of the desktop initiative. Builds ONLY the Xvfb DDX (headless
# software framebuffer): no hardware/DRM/GL, no udev/logind, no xorg/xephyr/etc.
# x11vnc (Task 7a) later bridges the Xvfb display to VNC.
#
# XLibre has BSD CI but no illumos/Hammerhead target, so this port carries
# Hammerhead portability patches in patches/ (applied below).
#
# Meson option notes (verified against this tree's meson_options.txt):
#   * -Dgbm / -Dxf86-input-null from the original manifest capture do NOT
#     exist as options in 25.1.8 and are intentionally dropped (gbm is only
#     ever probed as required:false, and the null input driver isn't an
#     option here). Intent preserved: Xvfb on, all hardware/GL/DRM off.
#   * -Dsha1=libcrypto uses base OpenSSL's libcrypto (find_library('crypto')
#     resolves /usr/lib/libcrypto.so; <openssl/sha.h> in base /usr/include).
#   * libdrm/pciaccess/epoxy/gbm are all probed required:false in meson.build,
#     so the -D*=false switches don't trip a hard missing-dependency error on
#     Hammerhead (none of those libs exist here). Verified by source read.
