CXX      ?= g++
CXXFLAGS ?= -fPIC -O2 -Wall -Woverloaded-virtual
PKG-CONFIG ?= pkg-config

### The directory environment:

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

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config

# 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 = image

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

APIVERSION = $(shell grep 'define APIVERSION ' $(VDRDIR)/config.h | awk '{ print $$3 }' | sed -e 's/"//g')

### The name of the distribution archive:

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

### The version number of ffmpeg (taken from "libavcodec/avcodec.h" ):

ifdef FFMDIR
LIBAVCODECVERSION = $(shell grep "\#define LIBAVCODEC_VERSION " $(FFMDIR)/libavcodec/avcodec.h | \
                    awk '{ print $$3 }' | cut -d "." -f 1 )
endif

### The subdirectories:

SUBDIRS = liboutput libimage

### Implicit rules:

%.o: %.c

### Internationalization (I18N):

PODIR     = po
LOCALEDIR = $(VDRDIR)/locale
I18Npo    = $(wildcard $(PODIR)/*.po)
I18Nmo    = $(addsuffix .mo, $(foreach file, $(I18Npo), $(basename $(file))))
