# Build script for st (suckless, plain Makefile - NO configure, NOT a
# template build). Deps: libX11, libXft, fontconfig, freetype.
#
# st's shipped config.mk hardcodes X11INC/X11LIB to /usr/X11R6 (doesn't
# exist on Hammerhead) and links -lX11/-lXft directly instead of going
# through pkg-config. Rewrite config.mk to resolve everything via
# pkg-config against $PREFIX (falls back cleanly since x11/xft/
# fontconfig/freetype2 .pc files all live under $PREFIX/lib/pkgconfig).

# __linux / __OpenBSD__ / __NetBSD__ / __APPLE__ / __FreeBSD__ /
# __DragonFly__ - none of which match illumos-derived GCC (which defines
# __sun / __SVR4 instead), so no header gets included at all and openpty()
# is an implicit (and on this GCC, fatal-by-default) declaration. openpty()
# lives in libutil.h on illumos, same as the FreeBSD/DragonFly branch -
# add a __sun arm alongside it.

# GOTCHA: the Makefile's `install` target ends with `tic -sx st.info` to
# register st's terminfo entry. That's GNU-ncurses tic syntax; Hammerhead
# only ships illumos' native SVR4 /usr/bin/tic, which doesn't understand
# -s/-x and errors out ("Unknown option"), taking `gmake install` down
# with it even though the binary+man install (the two steps before it)
# already succeeded. Do the bin/man install ourselves and treat terminfo
# registration as best-effort (harmless if it's a no-op - st still runs
# fine falling back to $TERM=xterm-compatible entries already present).
