NXT_USB is a C++ library used to control a LEGO Mindstorms NXT robot over a USB connection.

This code was modified from:
*NXT++: http://nxtpp.sourceforge.net
*Device::USB: http://search.cpan.org/~gwadej/Device-USB-0.21

= Linux Installation =

== Reqirements ==
# This code can be used only on a Linux distribution with root access.  Remember to run any software utilizing this code as root.
# libusb: http://libusb.sourceforge.net/

== Instructions ==
Download libusb from:
  http://libusb.sourceforge.net (version 0.1.12)

Then run:
  tar zxvf libusb-0.1.12.tar.gz
  cd libusb-0.1.12/
  ./configure CFLAGS=-funsigned-char --prefix=<your libusb directory> --exec-prefix=<your libsub directory>
  make
  make install

Then add the libusb directory to your $LD_LIBRARY_PATH variable.
Note that the INSTALL.libusb file has information about the installation process.

Another alternative is to use CMake:

  SET(CMAKE_CXX_FLAGS
    "-funsigned-char"
  )

  INCLUDE_DIRECTORIES(
    ...
    <your libusb directory (can be a relative path)>
  )

  ADD_LIBRARY(<your library name>
    ...
    NXT_USB.cxx
    NXT_USB_linux.cxx
  )

  FIND_LIBRARY(LIBUSB_LIB
    NAMES libusb-lib
    PATHS
     <your libusb directory (can be a relative path)>/lib
  )

  TARGET_LINK_LIBRARIES(Lego
    ...
    <your libusb directory (should be an absolute path)>/lib/libusb.so
  )

The simplest way to use this library is to keep the four NXT_USB files (NXT_USB.h, NXT_USB.cxx, NXT_USB_linux.h, and NXT_USB_linux.cxx) in the same directory as your program.  Simply #include "NXT_USB.h" and compile as usual.
