#
# 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.

### Configuration (edit this for your needs)

# Source documentation:

# enable this to write the OSD as png into /tmp (only GLES mode)
PNG ?= 0
# enable this to mark the corners of the rectangles on the OSD
GRID ?= 0

VERSION = $(shell grep 'static const char \*const VERSION *=' $(PLUGIN).cpp | awk '{ print $$7 }' | 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))

#
TMPDIR ?= /tmp

### The compiler options:

export CFLAGS	= $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

ifeq ($(CFLAGS),)
$(warning CFLAGS not set)
endif
ifeq ($(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:
