# 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 = systeminfo

### 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:
#VDRDIR = ../../..

# 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)

### 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 -g -O2 -Wall -Woverloaded-virtual -Wno-parentheses

### 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)

LOCDIR = $(VDRDIR)/locale

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

DEFINES += -D_GNU_SOURCE

INCLUDES += -I$(VDRDIR)/include

### Run 'install' for target 'all':

all: install

OLD_I18N = 1

i18n install-i18n:

endif
endif # compatibility section

### 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 += -I$(VDRDIR)/include

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

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

OBJS = $(PLUGIN).o displayinfo.o

### The main target:

all: $(SOFILE) i18n

### Implicit rules:

### Dependencies:
