# 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 = remote

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

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:
PKG_CONFIG ?= pkg-config
PKGCFG = $(if $(VDRDIR),$(shell $(PKG_CONFIG) --variable=$(1) $(VDRDIR)/vdr.pc),$(shell $(PKG_CONFIG) --variable=$(1) vdr || $(PKG_CONFIG) --variable=$(1) ../../../vdr.pc))
LIBDIR = $(DESTDIR)$(call PKGCFG,libdir)
LOCDIR = $(DESTDIR)$(call PKGCFG,locdir)

#
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 stuff
ifeq ($(LOCDIR),)
### The C++ compiler and options:

CXX      ?= g++
CXXFLAGS ?= -fPIC -O2 -Wall -Woverloaded-virtual

### The directory environment:

VDRDIR = ../../..
LIBDIR = ../../lib

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config

### The version number of VDR's plugin API (taken from VDR's "config.h"):

APIVERSION = $(shell sed -ne '/define APIVERSION/s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/config.h)

ifeq ($(APIVERSION),)
### Backward compatibility: use version number of VDR!
APIVERSION = $(shell sed -ne '/define VDRVERSION/s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/config.h)
endif

LOCDIR = $(VDRDIR)/locale
