More Teensy3.1 Makefile Questions

I am switching over to a Teensy3.1 from a Teensy 2.0.

I want to use C code to be able to access some features (Quadrature Decoding on the Flex Timer Module).

So the first step is getting the Makefile working and I am a Makefile newbie.

I edited the included Makefile

Code: 
# The name of your project (used to name the compiled .hex file)
TARGET = main

# configurable options
OPTIONS = -DF_CPU=48000000 -DUSB_SERIAL -DLAYOUT_US_ENGLISH

# options needed by many Arduino libraries to configure for Teensy 3.0
OPTIONS += -D__MK20DX128__ -DARDUIO=104


#************************************************************************
# Location of Teensyduino utilities, Toolchain, and Arduino Libraries.
# To use this makefile without Arduino, copy the resources from these
# locations and edit the pathnames.  The rest of Arduino is not needed.
#************************************************************************

# path location for Teensy Loader, teensy_post_compile and teensy_reboot
TOOLSPATH = ../../../ARM/Arduino/arduino-1.0.5/hardware/tools   # on Linux
#TOOLSPATH = ../../../tools/avr/bin   # on Mac or Windows

# path location for the arm-none-eabi compiler
COMPILERPATH = ../../../ARM/Arduino/arduino-1.0.5/hardware/tools/arm-none-eabi/bin

#************************************************************************
# Settings below this point usually do not need to be edited
#************************************************************************

# CPPFLAGS = compiler options for C and C++
CPPFLAGS = -Wall -g -Os -mcpu=cortex-m4 -mthumb -nostdlib -MMD $(OPTIONS) -I.

# compiler options for C++ only
CXXFLAGS = -std=gnu++0x -felide-constructors -fno-exceptions -fno-rtti

# compiler options for C only
CFLAGS =

# linker options
LDFLAGS = -Os -Wl,--gc-sections -mcpu=cortex-m4 -mthumb -Tmk20dx128.ld

# additional libraries to link
LIBS = -lm


# names for the compiler programs
CC = $(abspath $(COMPILERPATH))/arm-none-eabi-gcc
CXX = $(abspath $(COMPILERPATH))/arm-none-eabi-g++
OBJCOPY = $(abspath $(COMPILERPATH))/arm-none-eabi-objcopy
SIZE = $(abspath $(COMPILERPATH))/arm-none-eabi-size

# automatically create lists of the sources and objects
# TODO: this does not handle Arduino libraries yet...
C_FILES := $(wildcard *.c)
CPP_FILES := $(wildcard *.cpp)
OBJS := $(C_FILES:.c=.o) $(CPP_FILES:.cpp=.o)


# the actual makefile rules (all .o files built by GNU make's default implicit rules)

all: $(TARGET).hex

$(TARGET).elf: $(OBJS) mk20dx128.ld
	$(CC) $(LDFLAGS) -o $@ $(OBJS) $(LIBS)

%.hex: %.elf
	$(SIZE) $<
	$(OBJCOPY) -O ihex -R .eeprom $< $@
	$(abspath $(TOOLSPATH))/teensy_post_compile -file=$(basename $@) -path=$(shell pwd) -tools=$(abspath $(TOOLSPATH))
	-$(abspath $(TOOLSPATH))/teensy_reboot


# compiler generated dependency info
-include $(OBJS:.o=.d)

clean:
	rm -f *.o *.d $(TARGET).elf $(TARGET).hex

and am trying to compile the sample program

Code: 
#include "WProgram.h"

extern "C" int main(void)
{

	// To use Teensy 3.0 without Arduino, simply put your code here.
	// For example:

	pinMode(13, OUTPUT);
	while (1) {
		digitalWriteFast(13, HIGH);
		delay(500);
		digitalWriteFast(13, LOW);
		delay(500);
	}

}

I get the error
main.cpp|1 col 22| fatal error: WProgram.h: No such file or directory

How to tell the Makefile/program where to find the #include files. I am used to using the <avr\xxx.h> for Teensy 2.0.

Thanks,

Quick question:

The default Makefile included under arduino-1.0.5\hardware\teensy\cores\teensy3 includes the line:

Code: 
# options needed by many Arduino libraries to configure for Teensy 3.0
OPTIONS += -D__MK20DX128__ -DARDUIO=104

Does DARDUIO refer to the Arduino version and have to be updated to 105?

I updated MK20DX128 to MK20DX256 for Teensy 3.1.

Blinky works fine with the original line, but I assume there might be something more sophisticated where it matters.

Is there supposed to be a teensy31 directory somewhere? Or am I looking in a completely wrong place.

I am looking at the default Makefile included under arduino-1.0.5\hardware\teensy\cores\teensy3

From the website:
To use Teensy 3.0 without Arduino, first install Teensyduino. A sample makefile is installed in hardware/teensy/cores/teensy3
Click to expand...

I just ran the Teensyduino 1.18-rc1 Installer. The date stamp shows it updated this Makefile.

The Makefile is still configured for Teensy 3.0 and Arduino 1.0.4.

Code: 
# options needed by many Arduino libraries to configure for Teensy 3.0
OPTIONS += -D__MK20DX128__ -DARDUIO=104

I couldn't find any other Teensy3+ Makefile under the directory structure.

Is there an updated version of the sample Makefile past the one that has

Code: 
# options needed by many Arduino libraries to configure for Teensy 3.0
OPTIONS += -D__MK20DX128__ -DARDUIO=104

If so, it is not showing up in the Windows XP version of Teensyduino 1.18-rc1.

Re your response

You have an old version. This typo was fixed some time ago.

I have re-downloaded and re-ran to make sure I have the latest version available. And the installer says Teensyduino 1.18-rc1 Installer
