# Name of the plugin

PLUGIN = graphtft

### The version number of this plugin (taken from the main source file):

VERSION = $(shell grep 'static const char\* VERSION *=' $(PLUGIN).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:

#
TMPDIR ?= /tmp

### The compiler options:

export CFLAGS   = $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags) -fPIC -Wno-unused-result

### 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)

SOFILE = libvdr-$(PLUGIN).so
