PLUGIN   = seduatmo
HISTFILE = "HISTORY.h"

### 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')

LASTHIST    = $(shell grep '^20[0-3][0-9]' $(HISTFILE) | head -1)
LASTCOMMENT = $(subst |,\n,$(shell sed -n '/$(LASTHIST)/,/^ *$$/p' $(HISTFILE) | tr '\n' '|'))
LASTTAG     = $(shell git describe --tags --abbrev=0)
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) -fPIC

CXXFLAGS += -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

### Includes and Defines (add further entries here):

INCLUDES +=

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'

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

OBJS = $(PLUGIN).o
OBJS += seduthread.o common.o config.o ledsconf.o seduservice.o

### The main target:

all: $(SOFILE) i18n

### Implicit rules:

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

### Dependencies:

MAKEDEP = $(CXX) -MM -MG

-include $(DEPFILE)
