# 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.

### The version number of this plugin (taken from the version header file):
VERSION = $(shell grep 'static const char \*VERSION *=' version.h | awk '{ print $$6 }' | sed -e 's/[";]//g')

### 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_PATH="$$PKG_CONFIG_PATH:../../../.." $(PKG_CONFIG) --variable=$(1) vdr))
LIBDIR = $(call PKGCFG,libdir)
LOCDIR = $(call PKGCFG,locdir)
#
TMPDIR ?= /tmp

### The compiler options:
export CFLAGS   = $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

### compiler version dependent options
CXXVERSION=$(shell $(CXX) -dumpversion | cut -d"." -f1)
$(info version:  ${CXXVERSION})
ifeq ($(CXXVERSION),4)
	export CXXFLAGS += -std=c++11   # to prevent a lot of compiler warnings with g++ V4
endif
ifeq ($(CXXVERSION),5)
        export CXXFLAGS += -std=c++11   # to prevent compiler errors with g++ V5
endif
ifeq ($(CXXVERSION),13)                 # prevent "warning: "_FORTIFY_SOURCE" redefined"
        ifneq (,$(findstring D_FORTIFY_SOURCE,$(CXXFLAGS)))
                export CXXFLAGS := -U_FORTIFY_SOURCE $(CXXFLAGS)   # append before options from vdr.pc
        endif
endif

### The version number of VDR's plugin API:
APIVERSION = $(call PKGCFG,apiversion)
$(info VDR plugin API version is ${APIVERSION})

### The name of the distribution archive:
ARCHIVE = $(PLUGIN)-$(VERSION)
PACKAGE = vdr-$(ARCHIVE)

SOFILE = libvdr-$(PLUGIN).so
