Qtopia how to install i2c-tools ???

Hi, 

I have a question. How I can install i2c-tools ?

thanks.

In the Makefile for i2c-tools replace the line:
CC  := gcc
with
CC  := arm-linux-gcc

Run make to build.

Then copy the resulting binaries to the FriendlyARM and run them...

This does not work.
I compiled with arm-linux-gcc and copied the binaries to 2440.
when i run and i2c-tools command it gives this error:
line 1: syntax error: "(" unexpected

Found out the way..
You also need to change 
CC  := gcc
with
CC  := arm-linux-gcc
OR replace $(CC) with arm-linux-gcc every where
in i2c-tools/tools/Module.mk

Now run make and copy binery files in i2c-tools/tools/ to your FriendlyARM

Hi,

which Python version did you use to compile 2.7 or 3.2?
I try to build only py-smbus, with python 3.2 as a first step, before go to
compile it for arm. But the command python3.2 ./setup.py build failes with
the following errors:
running build
running build_ext

Ok, it tried compile i2c-tools-3.1.0 with Python 2.7 and it work under
Ubuntu 12.04.
Has anyone an idea how to compile it with Python 3.2 and which changes has
to be done in the smbusmodule.c code?
