# Features

# Uncomment to enable use of sqrt() function in monitor distance calculations.
OPT_CPPFLAGS += -DHAVE_MATH_H
OPT_LDLIBS += -lm

# Uncomment to enable info banner on holding Ctrl+Alt+I.
OPT_CPPFLAGS += -DINFOBANNER

# Uncomment to show the same banner on moves and resizes.  Can be SLOW!
#OPT_CPPFLAGS += -DINFOBANNER_MOVERESIZE

# Uncomment to support the Xrandr extension (thanks, Yura Semashko).
OPT_CPPFLAGS += -DRANDR
OPT_LDLIBS   += -lXrandr

# Uncomment to support shaped windows.
OPT_CPPFLAGS += -DSHAPE
OPT_LDLIBS   += -lXext

# Uncomment to enable solid window drags.  This can be slow on old systems.
OPT_CPPFLAGS += -DSOLIDDRAG

# Uncomment to move pointer around on certain actions.
#OPT_CPPFLAGS += -DWARP_POINTER

# Uncomment to use Ctrl+Alt+q instead of Ctrl+Alt+Escape.  Useful for Cygwin.
#OPT_CPPFLAGS += -DKEY_KILL=XK_q

# Uncomment to include whatever debugging messages I've left in this release.
#OPT_CPPFLAGS += -DDEBUG   # miscellaneous debugging
#OPT_CPPFLAGS += -DXDEBUG  # show some X calls

OPT_CPPFLAGS += -DNDEBUG  # disable asserts

# Uncomment to map KEY_TOPLEFT to XK_z (suitable for quertz keyboards)
#OPT_CPPFLAGS += -DQWERTZ_KEYMAP

# Include file and library paths

# Most Linux distributions don't separate out X11 from the rest of the
# system, but some other OSs still require extra information:

# Solaris 10:
#OPT_CPPFLAGS += -I/usr/X11/include
#OPT_LDFLAGS += -R/usr/X11/lib -L/usr/X11/lib

# Solaris <= 9 doesn't support RANDR feature above, so disable it there
# Solaris 9 doesn't fully implement ISO C99 libc, to suppress warnings, use:
#OPT_CPPFLAGS += -D__EXTENSIONS__

# OpenBSD 6.2
#OPT_CPPFLAGS += -I/usr/X11R6/include
#OPT_LDFLAGS += -L/usr/X11R6/lib

# Mac OS X:
#OPT_LDFLAGS += -L/usr/X11R6/lib
