#
# Makefile for the 'LIVE' 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.
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')

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

### 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 = $(call PKGCFG,libdir)
LOCDIR = $(call PKGCFG,locdir)
PLGCFG = $(call PKGCFG,plgcfg)
#
TMPDIR ?= /tmp

### The compiler options:
export CFLAGS   = $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

ECPPC ?= ecppc

### The version number of VDR's plugin API:
APIVERSION = $(call PKGCFG,apiversion)

### Allow user defined options to overwrite defaults:
-include $(PLGCFG)

### Determine tntnet and cxxtools versions:
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 }')
CXXTOOLVER = $(shell cxxtools-config --version | sed -e's/\.//g' | sed -e's/pre.*//g' | awk '/^..$$/ { print $$1."000"} /^...$$/ { print $$1."00"} /^....$$/ { print $$1."0" } /^.....$$/ { print $$1 }')

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

### export all vars for sub-makes, using absolute paths
LIBDIR := $(shell cd $(LIBDIR) >/dev/null 2>&1 && pwd)
LOCDIR := $(shell cd $(LOCDIR) >/dev/null 2>&1 && pwd)
export
unexport PLUGIN

### 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):
DEFINES	 += -D_GNU_SOURCE -DPLUGIN_NAME_I18N='"$(PLUGIN)"' -DTNTVERSION=$(TNTVERSION) -DCXXTOOLVER=$(CXXTOOLVER)
SUBDIRS	  = pages css javascript
VERSIONSUFFIX = gen_version_suffix.h
