##
## Installation paths
##

# Installation path prefix. Unless you know what you're doing, the default
# of /usr/local is likely the correct choice.
PREFIX=/usr/local

# Unless you are creating a package conforming to some OS's standards, you
# probably do not want to modify the following directories:

# Main binaries
BINDIR=$(PREFIX)/bin
# Configuration .lua files
ETCDIR=$(PREFIX)/etc/ion3
# Some .lua files and ion-* shell scripts
SHAREDIR=$(PREFIX)/share/ion3
# Manual pages
MANDIR=$(PREFIX)/share/man
# Some documents
DOCDIR=$(PREFIX)/share/doc/ion3
# Nothing at the moment
INCDIR=$(PREFIX)/include/ion3
# Nothing at the moment
LIBDIR=$(PREFIX)/lib
# Modules
MODULEDIR=$(LIBDIR)/ion3/mod
# Compiled Lua source code
LCDIR=$(LIBDIR)/ion3/lc
# ion-completefile (does not belong in SHAREDIR being a binary file)
EXTRABINDIR=$(LIBDIR)/ion3/bin
# For ion-completeman system-wide cache
VARDIR=/var/cache/ion3
# Message catalogs
LOCALEDIR=$(PREFIX)/share/locale

# Executable suffix (for Cygwin).
#BIN_SUFFIX = .exe


##
## Modules
##

# Set PRELOAD_MODULES=1 if your system does not support dynamically loaded
# modules through 'libdl' or has non-standard naming conventions.
# You will likely need this option on e.g. Cygwin and Mac OS X.
#PRELOAD_MODULES=1

# Flags to link with libdl. Even if PRELOAD_MODULES=1, you may need this
# setting (for e.g. Lua, when not instructed by pkg-config).
DL_LIBS=-ldl


##
## Lua
##

# If you have installed Lua 5.1 from the official tarball without changing
# paths, this should do it.
LUA_DIR=/usr/local
LUA_LIBS = -L$(LUA_DIR)/lib -llua
LUA_INCLUDES = -I$(LUA_DIR)/include
LUA=$(LUA_DIR)/bin/lua
LUAC=$(LUA_DIR)/bin/luac

# If you are using the Debian packages, the following settings should be
# what you want.
#LUA_LIBS=`pkg-config --libs lua5.1`
#LUA_INCLUDES=`pkg-config --cflags lua5.1`
#LUA=/usr/bin/lua5.1
#LUAC=/usr/bin/luac5.1

## X libraries, includes and options

# Paths
X11_PREFIX=/usr/X11R6
# SunOS/Solaris
#X11_PREFIX=/usr/openwin

X11_LIBS=-L$(X11_PREFIX)/lib -lX11 -lXext
X11_INCLUDES=-I$(X11_PREFIX)/include

# XFree86 libraries up to 4.3.0 have a bug that can cause a segfault.
# The following setting  should  work around that situation.
DEFINES += -DCF_XFREE86_TEXTPROP_BUG_WORKAROUND

# Use the Xutf8 routines (XFree86 extension) instead of the Xmb routines
# in an UTF-8 locale. (No, you don't need this in UTF-8 locales, and 
# most likely don't even want. It's only there because both Xmb and 
# Xutf8 routines are broken, in different ways.)
#DEFINES += -DCF_DE_USE_XUTF8

# Remap F11 key to SunF36 and F12 to SunF37? You may want to set this
# on SunOS.
#DEFINES += -DCF_SUN_F1X_REMAP


##
## Localisation
##

# If you're on an archaic system (such as relatively recent *BSD releases)
# without even dummy multibyte/widechar and localisation support, you may 
# have to uncomment the following line:
#DEFINES += -DCF_NO_LOCALE -DCF_NO_GETTEXT

# On some other systems you may need to explicitly link against libintl.
#EXTRA_LIBS += -lintl
# You may also need to give the location of its headers. The following
# should work on Mac OS X (which needs the above option as well) with
# macports.
#EXTRA_INCLUDES += -I/opt/local/include


##
## libc
##

# You may uncomment this if you know that your system C libary provides
# asprintf and  vasprintf. (GNU libc does.) If HAS_SYSTEM_ASPRINTF is not
# defined, an implementation provided in libtu/sprintf_2.2/ is used. 
#HAS_SYSTEM_ASPRINTF=1

# The following setting is needed with GNU libc for clock_gettime and the
# monotonic clock. Other systems may not need it, or may not provide a
# monotonic clock at all (which Ion can live with, and usually detect).
EXTRA_LIBS += -lrt

# Cygwin needs this.
#DEFINES += -DCF_NO_GETLOADAVG


#
# If you're using/have gcc, it is unlikely that you need to modify
# any of the settings below this line.
