# 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 = vdrboblight

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

#VERSION = $(shell grep 'static const char \*VERSION *=' vdrboblight.h | awk '{ print $$6 }' | sed -e 's/[";]//g')
VERSION := $(shell git describe --tags master)

### 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)

### Allow user defined options to overwrite defaults:

-include $(PLGCFG)

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

APIVERSION = $(call PKGCFG,apiversion)
ifeq ($(strip $(APIVERSION)),)
APIVERSION = $(shell grep 'define APIVERSION ' $(VDRDIR)/config.h | awk '{ print $$3 }' | sed -e 's/"//g')
NOCONFIG := 1
endif

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

ifdef API1733

VDRSRC = $(VDRDIR)
ifeq ($(strip $(VDRSRC)),)
VDRSRC := ../../..
endif
LIBDIR = $(VDRSRC)/PLUGINS/lib

ifndef NOCONFIG
CXXFLAGS = $(call PKGCFG,cflags)
CXXFLAGS += -g -O3 -Wall -Werror=overloaded-virtual -Wno-parentheses -fPIC
else
-include $(VDRSRC)/Make.global
-include $(VDRSRC)/Make.config
endif

export CXXFLAGS
endif

### 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):

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

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'
### Define GITVERSION used in vdrboblight.c
DEFINES += -DGITVERSION='"$(VERSION)"'

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

OBJS = $(patsubst %.c,%.o,$(wildcard *.c))

### The main target:

ifdef API1733
all: install
else
all: $(SOFILE) $(DEVPLUGTARGETS)
endif

### Implicit rules:

%.o: %.c
	$(CXX) $(CXXFLAGS) -c $(DEFINES) $(INCLUDES) -o $@ $<

### Dependencies:
