#  ======== makefile =======
#  GNUmake-based makefile for linuxonly speech sample app.
#

# This file simulates the build for a generic Linux application that
# happens to use Codec Engine. This makefile has special sections to
# accomodate inclusion of the codec engine, while the rest is standard.
# Codec Engine-specific additions are marked with the [CE] tag.

# [CE] define AUDCP_ROOTDIR to point to root of example directory
AUDCP_ROOTDIR := $(CURDIR)/..

# [CE] include the file that defines paths to XDC packages and XDC tools
include $(AUDCP_ROOTDIR)/xdcpaths.mak

# [CE] add the examples directory itself to the list of paths to packages
XDC_PATH := $(AUDCP_ROOTDIR);$(XDC_PATH)

# [CE] include the makefile that runs XDC configuration step for our
# program configuration script.
#
# Input:
# XDC_CFGFILE: location of the program configuration script (if in different
#              directory, include the relative path to the file)
# Implicit input: XDC_ROOT and XDC_PATH defined by the xdcpaths.mak above
#
# Output:
# XDC_FLAGS:   additional compiler flags that must be added to existing 
#              CFLAGS or CPPFLAGS
# XDC_CFILE:   name of the XDC-generated C file; usually does not need to be
#              used explicitly, the existing .c->.o rules will take care of it
# XDC_OFILE:   name of object file produced by compiling XDC-generated C file;
#              must be linked with the user's application
# XDC_LFILE:   list of Codec Engine libraries that must be supplied to the
#              linker (usually as `cat $(XDC_LFILE)`)
# Implicit output: rule that generates .c file from the program configuration
#              script (XDC_CFGFILE); rule to generate dummy package one dir.
#              level below the script; rule that cleans generated files

# File "xdccfg_linuxarm.mak" is included here to run XDC configuration step.
XDC_CFGFILE = ./ceapp.cfg
include       $(AUDCP_ROOTDIR)/xdccfg_linuxarm.mak

# [CE] Augment the standard $(CPPFLAGS) variable, adding the
# $(XDC_FLAGS) variable, defined by the file above, to it.
CPPFLAGS += $(XDC_FLAGS)


# "normal" makefile settings and rules follow, with some additions for CE
# This app consists of the main, codec-engine unrelated app.c file, and
# the codec-engine-using appcfg.c file.
