#
# Makefile for the Vodcatcher VDR 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 = vodcatcher

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

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

### The C++ compiler and options:

CXX      ?= g++
CXXFLAGS ?= -fPIC -O2 -Wall -Woverloaded-virtual

### The directory environment:

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

### Conditionals:
#DEBUG=1

### Some defaults that can be overriden:

DEFAULT_CACHE_DIR = /var/cache/vdr-plugin-vodcatcher

### 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)
