#
# Makefile for a Video Disk Recorder plugin
#
# $Id$

# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.

PLUGIN = graphlcd

### The version number of this plugin (taken from the main source file):

VERSION = $(shell grep 'static const char \*VERSION *=' plugin.c | awk '{ print $$6 }' | sed -e 's/[";]//g')

### The directory environment:

# Use package data if installed...otherwise assume we're under the VDR source directory:
PKGCFG = $(if $(VDRDIR),$(shell pkg-config --variable=$(1) $(VDRDIR)/vdr.pc),$(shell pkg-config --variable=$(1) vdr || pkg-config --variable=$(1) ../../../vdr.pc))
LIBDIR = $(DESTDIR)$(call PKGCFG,libdir)
LOCDIR = $(DESTDIR)$(call PKGCFG,locdir)
PLGCFG = $(call PKGCFG,plgcfg)
#
TMPDIR ?= /tmp

### The compiler options:

export CFLAGS   = $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

### The version number of VDR's plugin API:

APIVERSION = $(call PKGCFG,apiversion)

### Allow user defined options to overwrite defaults:

ifeq ($(PLGCFG),)
    VDRDIR ?= ../../..
    PLGCFG = $(VDRDIR)/Make.config
endif
-include $(PLGCFG)

# fallback for building against old VDR versions (like 1.4.7) in the VDR source tree, where you should have Make.config
ifeq ($(LIBDIR),)
    LIBDIR = ../../lib
endif
INCDIR ?= $(VDRDIR)
PREFIX ?= /usr

# make sure to have a correct RESDIR
MYRESDIR = $(call PKGCFG,resdir)
ifeq ($(MYRESDIR),)
    MYRESDIR = /usr/share/vdr
endif
RESDIR := $(DESTDIR)$(MYRESDIR)/plugins/$(PLUGIN)

# make sure to always have a correct APIVERSION
ifeq ($(strip $(APIVERSION)),)
  APIVERSION = $(shell grep 'define APIVERSION ' $(VDRDIR)/config.h | cut -d'"' -f2)
endif

# define this if you built graphlcd-base with freetype:
HAVE_FREETYPE2 ?= 1

# define this if femon-plugin <= 1.7.7 is used AND which has already been patched (see README)
# either define this setting here or in $VDRDIR/Make.config or in $VDRDIR/Make.global
HAVE_VALID_FEMON ?= 0

# define the path to the graphlcd.conf file. if not defined, path = "/etc/graphlcd.conf"
#PLUGIN_GRAPHLCDCONF = "$(CONFDIR)/plugins/$(PLUGIN)/graphlcd.conf"

# defines if installing of TTF should be omitted (default is to install)
SKIP_INSTALL_TTF ?= 0

# defines if installing of documentation should be omitted (default is to install)
SKIP_INSTALL_DOC ?= 0

# if we install the documentation ourselves, do it here:
export INSTALLDOCDIR = $(DESTDIR)$(PREFIX)/share/doc/vdr-$(PLUGIN)-$(VERSION)


### The name of the distribution archive:

ARCHIVE = $(PLUGIN)-$(VERSION)
PACKAGE = vdr-$(ARCHIVE)

### The name of the shared object file:

SOFILE = libvdr-$(PLUGIN).so

### Includes and Defines (add further entries here):

INCLUDES += -I./graphlcd-base/ -I$(INCDIR)/include -I$(PREFIX)/include

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'

ifneq ($(HAVE_FREETYPE2), 0)

# if we add documentations to additional install targets
ifeq ($(SKIP_INSTALL_DOC), 0)
    INS_TARGET_DOCS = docs

### The object files (add further files here):

OBJS = alias.o common.o display.o menu.o plugin.o setup.o skinconfig.o state.o strfct.o service.o extdata.o

ifneq ($(shell grep -l 'Phrases' $(VDRDIR)/i18n.c),$(VDRDIR)/i18n.c)
