PLUGIN    = graphtftng

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

VERSION = $(shell grep 'define _VERSION ' $(HISTFILE) | awk '{ print $$3 }' | sed -e 's/[";]//g')
LASTHIST    = $(shell grep '^\#[0-9][0-9]' $(HISTFILE) | head -1)

BRANCH      = $(shell git rev-parse --abbrev-ref HEAD)
GIT_REV     = $(shell git describe --always 2>/dev/null)

# 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) -ggdb -fPIC -Wall -Wunused-variable -Wunused-label -Wunused-value -Wunused-function -Wno-unused-result

### 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
