Makefile

#
# Makefile for a Video Disk Recorder plugin
#
# $Id$

# 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 = mlist

### Set this to '0' if you don't want mlist to auto-configure itself
AUTOCONFIG=1

### If AUTOCONFIG is not active,you can manually enable the
### optional modules or patches for other plugins:

ifeq ($(AUTOCONFIG),0)
	# If you want to use Perl compatible regular expressions (PCRE) or libtre for
	# unlimited fuzzy searching, uncomment this and set the value to pcre/pcre2
	# or tre; also have a look at INSTALL for further notes on this.
	#REGEXLIB = pcre2
endif

### 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')

# 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)
PLGCFG = $(call PKGCFG,plgcfg)
#
TMPDIR = /tmp

### The compiler options:

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

### The module configuration:

ifeq ($(AUTOCONFIG),1)
	ifeq (exists, $(shell $(PKG_CONFIG) libpcre2-posix && echo exists))
		REGEXLIB = pcre2
	else ifeq (exists, $(shell $(PKG_CONFIG) libpcre && echo exists))
		REGEXLIB = pcre
	else ifeq (exists, $(shell $(PKG_CONFIG) tre && echo exists))
		REGEXLIB = tre
	endif
endif

### The PCRE settings:

ifeq ($(REGEXLIB), pcre2)
	LIBS += $(shell pcre2-config --libs-posix)
	INCLUDE += $(shell pcre2-config --cflags)
	DEFINES += -DHAVE_PCRE2POSIX
else ifeq ($(REGEXLIB), pcre)
	LIBS += $(shell pcre-config --libs-posix)
	INCLUDE += $(shell pcre-config --cflags)
	DEFINES += -DHAVE_PCREPOSIX
else ifeq ($(REGEXLIB), tre)
	LIBS += -L$(shell $(PKG_CONFIG) --variable=libdir tre) $(shell $(PKG_CONFIG) --libs tre)
	DEFINES += -DHAVE_LIBTRE
	INCLUDE += $(shell $(PKG_CONFIG) --cflags tre)
endif

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

APIVERSION = $(call PKGCFG,apiversion)
DOXYFILE = Doxyfile
DOXYGEN  = doxygen

### 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 += -I$(call PKGCFG,incdir)
DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'

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

OBJS = $(PLUGIN).o

### Internationalization (I18N):

PODIR     = po
I18Npo    = $(wildcard $(PODIR)/*.po)
I18Nmo    = $(addsuffix .mo, $(foreach file, $(I18Npo), $(basename $(file))))
I18Nmsgs  = $(addprefix $(LOCDIR)/, $(addsuffix /LC_MESSAGES/vdr-$(PLUGIN).mo, $(notdir $(foreach file, $(I18Npo), $(basename $(file))))))
I18Npot   = $(PODIR)/$(PLUGIN).pot
