Compile C programs for asus routers

[sovking]

Hi,
I need to compile a C program to monitor some input on USB port.
(I need to compile this program).

I realize that I need to make cross-compiling. So, I create a Virtual Machine
with Ubuntu 12.04, and there I installed the necessary development tools and then the asus-merlin distribution for my RT-N66u.

Now my question is:
how I can use this building environment to make that program ?
What I have to set in my Makefile to get the right 'make' and 'gcc' working ?

Thanks in advance!

This is a simple solution I found:

Install a development environment for asus-merlin as described here.

Then create your Makefile following this template:

CC = mipsel-uclibc-gcc
CFLAGS = -O2 -Wall -pipe -mtune=mips32r2 -mips32r2 -isystem /home/youruser/asuswrt-merlin/release/src-rt/linux/linux-2.6/include -I./include
OFILES = main.o otherfile.o

TARGET = yourprogram

all:    $(TARGET)

$(TARGET): $(OFILES)
        $(CC) $(OFILES) -o $(TARGET)
        chmod 4711 $(TARGET)

main.o: Makefile main.c include/main.h include/otherfile.h 
        $(CC) $(CFLAGS) -c main.c

otherfile.o: Makefile comm.c include/main.h include/otherfile.h 
        $(CC) $(CFLAGS) -c comm.c

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

Do you think it would be possible for you to show me how to do this for this file? I'm trying to compile a version for 2.03 because I can't find the ipk anywhere.
