#
# 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.
# IMPORTANT: the presence of this macro is important for the Make.config
# file. So it must be defined, even if it is not used here!
#
PLUGIN = markad

### ffmpeg usage ####
#
# Set this to 0, if you don't want to use ffmpeg
AVCODEC = 0

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

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

### The C++ compiler and options:

CXX      ?= g++
CXXFLAGS ?= -fPIC -g -O0 -Wall -Woverloaded-virtual -Wno-parentheses
PKG-CONFIG ?= pkg-config

### The directory environment:

VDRDIR = ../../..
LIBDIR = ../../lib
TMPDIR = /tmp

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config

### The version number of VDR's plugin API (taken from VDR's "config.h"):

APIVERSION = $(shell sed -ne '/define APIVERSION/s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/config.h)

### The name of the distribution archive:

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

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

PKG-LIBS += libavcodec
PKG-INCLUDES += libavcodec

INCLUDES += -I$(VDRDIR)/include

DEFINES += -D_GNU_SOURCE -DPLUGIN_NAME_I18N='"$(PLUGIN)"'
DEFINES += -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE

ifeq ($(AVCODEC),1)
DEFINES += -DHAVE_AVCODEC
INCLUDES += $(shell $(PKG-CONFIG) --cflags $(PKG-INCLUDES))
LIBS += $(shell $(PKG-CONFIG) --libs $(PKG-LIBS))
endif

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

OBJS-CMD = markad-standalone.o
OBJS-COMMON = demux.o video.o audio.o decoder.o common.o ts2pkt.o pes2audioes.o
OBJS = $(PLUGIN).o recv.o status.o $(OBJS-COMMON)

### The main target:

all: libvdr-$(PLUGIN).so $(PLUGIN) i18n

### Implicit rules:

%.o: %.cpp
	$(CXX) $(CXXFLAGS) -c $(DEFINES) $(INCLUDES) $<

### Dependencies:

MAKEDEP = $(CXX) -MM -MG
DEPFILE = .dependencies
$(DEPFILE): Makefile
	@$(MAKEDEP) $(DEFINES) $(INCLUDES) $(OBJS:%.o=%.cpp) > $@
	@$(MAKEDEP) $(DEFINES) $(INCLUDES) $(OBJS-CMD:%.o=%.cpp) >> $@
