### 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 C++ compiler and options:

CXX      ?= g++
CXXFLAGS ?= -O2 -Wall -Woverloaded-virtual

### The directory environment:

DVBDIR = ../../../../DVB
VDRDIR = ../../..
LIBDIR = ../../lib
TMPDIR = /tmp

### Allow user defined options to overwrite defaults:

-include \$(VDRDIR)/Make.config

### The version number of VDR (taken from VDR's "config.h"):

VDRVERSION = \$(shell grep 'define VDRVERSION ' \$(VDRDIR)/config.h | awk '{ print \$\$3 }' | sed -e 's/"//g')

### The name of the distribution archive:

ARCHIVE = \$(PLUGIN)-\$(VERSION)
PACKAGE = vdr-\$(ARCHIVE)

### Includes and Defines (add further entries here):

INCLUDES += -I\$(VDRDIR)/include -I\$(DVBDIR)/include

DEFINES += -DPLUGIN_NAME_I18N='"\$(PLUGIN)"'

### The object files (add further files here):

OBJS = \$(PLUGIN).o

### Implicit rules:

%.o: %.c
	\$(CXX) \$(CXXFLAGS) -c \$(DEFINES) \$(INCLUDES) \$<

# Dependencies:

MAKEDEP = g++ -MM -MG
DEPFILE = .dependencies
\$(DEPFILE): Makefile

The next steps you should perform now are:

* fill in the code skeleton in "$PLUGIN_NAME.c" to implement your plugin function
* add further source files if necessary
* adapt the "Makefile" if necessary
* do "make plugins" from the VDR source directory to build your plugin
