# 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 = rpihddevice

### 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:

# 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)
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)

### 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
