# === USER SETTINGS ====================================================

# --- user settings relevant for all builds ----------------------------

# Specify this if you want to hard-code the operating system to appear
# in the lower-left hand corner of -mdoc manuals.
#
# CFLAGS	+= -DOSNAME="\"OpenBSD 5.5\""

# IFF your system supports multi-byte functions (setlocale(), wcwidth(),
# putwchar()) AND has __STDC_ISO_10646__ (that is, wchar_t is simply a
# UCS-4 value) should you define USE_WCHAR.  If you define it and your
# system DOESN'T support this, -Tlocale will produce garbage.
# If you don't define it, -Tlocale is a synonym for -Tacsii.
#
CFLAGS	 	+= -DUSE_WCHAR

CFLAGS		+= -g -DHAVE_CONFIG_H

# --- user settings related to database support ------------------------

# If you want to build without database support, for example to avoid
# the dependency on SQLite3, comment the following line.
# However, you won't get apropos(1) and makewhatis(8) in that case.
#
BUILD_TARGETS	+= db-build

# The remaining settings in this section
# are only relevant if db-build is enabled.
# Otherwise, they have no effect either way.

# If your system has manpath(1), uncomment this.  This is most any
# system that's not OpenBSD or NetBSD.  If uncommented, apropos(1)
# and makewhatis(8) will use manpath(1) to get the MANPATH variable.
#
#CFLAGS		+= -DUSE_MANPATH

# On some systems, SQLite3 may be installed below /usr/local.
# In that case, uncomment the following two lines.
#
#CFLAGS		+= -I/usr/local/include
#DBLIB		+= -L/usr/local/lib

# OpenBSD has the ohash functions in libutil.
# Comment the following line if your system doesn't.
#
DBLIB		+= -lutil

SBINDIR		 = $(PREFIX)/sbin

# --- user settings related to man.cgi ---------------------------------

# To build man.cgi, copy cgi.h.example to cgi.h, edit it,
# and enable the following line.
# Obviously, this requires that db-build is enabled, too.
#
#BUILD_TARGETS	+= cgi-build

# The remaining settings in this section
# are only relevant if cgi-build is enabled.
# Otherwise, they have no effect either way.

# If your system does not support static binaries, comment this,
# for example on Mac OS X.
