# 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 $$6 }' | sed -e 's/[";]//g')
$(shell GITVERSION=`git rev-parse --short HEAD 2> /dev/null``git status -uno --porcelain 2> /dev/null | grep -qc . && echo " patched"`; if [ "$$GITVERSION" ]; then if [ -f ../version.h ]; then LASTVERSION=`grep VERSION ../version.h | sed "s/^.*(\(.*\)).*$$/\1/"`; fi; if [ "$$GITVERSION" != "$$LASTVERSION" ]; then sed "s/\";/ ($$GITVERSION)\";/" ../version.dist > ../version.h; fi; else cp -p ../version.dist ../version.h; fi)

### 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))

### 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})
