#!/bin/sh
# Build script for tint2 (CMake, Ninja generator).
# Deps: cairo, pango, glib2, libX11, libXinerama, libXrandr, libXrender,
# libXcomposite, libXdamage, imlib2 (all ported).
#
# CMake doesn't recognize Hammerhead and won't set UNIX=TRUE / pick the
# right shared-lib conventions without a Platform module (same gotcha as
# base/libjpeg-turbo's cmake build) - map it to the SunOS platform module.
#
# ENABLE_BATTERY=OFF: no battery in a VM (task brief).
# ENABLE_TINT2CONF=OFF: tint2conf is a GTK+2 theme configurator - NO GTK
# anywhere per the toolkit-durability decision, and GTK+2 isn't ported.
# ENABLE_RSVG=OFF / ENABLE_SN=OFF: librsvg / libstartup-notification are
# not ported; both are optional (launcher SVG icons / startup-notification
# only) and tint2's CMakeLists gates them cleanly behind these options.

# GOTCHA (found 2026-07-22): src/util/window.c and src/util/timer.c use the
# BSD u_int32_t/u_int64_t typedefs, which illumos's <sys/types.h> does NOT
# provide (unlike glibc, which defines them unconditionally) - not even
# behind __EXTENSIONS__. window.c already includes <stdint.h>, so just
# swap the type names to their POSIX/C99 uintNN_t equivalents; timer.c
# needs the #include added too.

# <string.h>) - several tint2 files call it without including that header,
# an implicit-declaration error under GCC 14. Prepend the include to every
