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

RELEASE := $(shell grep 'static const char \*VERSION *=' $(PLUGIN).c | awk '{ print $$6 }' | sed -e 's/[";]//g')
SUBREL  := $(shell if test -d .git; then \
                     echo -n "-git-"; (git rev-parse --short HEAD 2>/dev/null || echo -n "Unknown") | sed -e 's/ .*//'; \
                   fi)
VERSION := $(RELEASE)$(SUBREL)
#VERSION = $(shell grep 'static const char \*VERSION *=' $(PLUGIN).c | awk '{ print $$6 }' | sed -e 's/[";]//g')

### 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_PATH="$$PKG_CONFIG_PATH:../../.." pkg-config --variable=$(1) vdr))
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)

### The version number of VDR's plugin API:

APIVERSION = $(call PKGCFG,apiversion)

# backward compatibility with VDR version < 1.7.34
API1733 := $(shell if [ "$(APIVERSION)" \< "1.7.34" ]; then echo true; fi; )

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

ifdef API1733
INCLUDES += -I$(VDRDIR)/include
endif

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'

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

OBJS = $(PLUGIN).o dish.o epghandler.o setupeepg.o equivhandler.o util.o eit2.o

### The main target:

ifdef API1733
all: libvdr-$(PLUGIN).so i18n
else
