### The version number of this plugin (taken from the main source file):
VERSION = $(shell grep 'const char\* WIRBELSCAN_VERSION *= ' wirbelscan.cpp | awk '{ print $$5 }' | 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)

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

### 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):
INCLUDES += $(shell pkg-config --cflags $(LIBREPFUNC))
DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'
LDFLAGS += $(shell pkg-config --libs $(LIBREPFUNC))
