#
# Makefile for a Video Disk Recorder plugin
#

# 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.
# IPORTANT: 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 = live

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

VERSION = $(shell grep '\#define LIVEVERSION ' setup.h | awk '{ print $$3 }' | sed -e 's/[";]//g')

### The C++ compiler and options:

CXX	 ?= g++
ECPPC	 ?= ecppc

### This variable is overriden in pages/Makefile because we don't want the
### extra warnings in the tntnet generated files. So if you change here
### something be sure to check pages/Makefile too.
CXXFLAGS ?= -fPIC -O2 -Wall
LDFLAGS	 ?= -fPIC -g

### Check for libpcre c++ wrapper
HAVE_LIBPCRECPP = $(shell pcre-config --libs-cpp)

### The directory environment:

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

### Make sure that necessary options are included:

-include $(VDRDIR)/Make.global

### 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/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/config.h)
I18NTARG   = $(shell if [ `echo $(APIVERSION) | tr [.] [0]` -ge "10507" ]; then echo "i18n"; fi)
TNTVERSION = $(shell tntnet-config --version | sed -e's/\.//g' | sed -e's/pre.*//g' | awk '/^..$$/ { print $$1."000"} /^...$$/ { print $$1."00"} /^....$$/ { print $$1."0" } /^.....$$/ { print $$1 }')
TNTVERS7   = $(shell ver=$(TNTVERSION); if [ $$ver -ge "1606" ]; then echo "yes"; fi)

CXXFLAGS  += $(shell tntnet-config --cxxflags)
LIBS      += $(shell tntnet-config --libs)

### Optional configuration features
PLUGINFEATURES =
ifneq ($(HAVE_LIBPCRECPP),)
	PLUGINFEATURES += -DHAVE_LIBPCRECPP
	CXXFLAGS       += $(shell pcre-config --cflags)
	LIBS           += $(HAVE_LIBPCRECPP)
endif

### The name of the distribution archive:

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

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

INCLUDES += -I$(VDRDIR)/include
ifneq ($(TNTVERS7),yes)
	INCLUDES += -Ihttpd

SUBDIRS	  = pages css javascript
ifneq ($(TNTVERS7),yes)
	SUBDIRS += httpd
endif

VERSIONSUFFIX = gen_version_suffix.h
