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_PATH="$$PKG_CONFIG_PATH:../../.." pkg-config --variable=$(1) vdr))

#
TMPDIR ?= /tmp

### The compiler options:

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

ifeq ($(CFLAGS),)
$(warning CFLAGS not set)
endif
ifeq ($(CXXFLAGS),)
$(warning CXXFLAGS not set)

### 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
