program. For example:

& vi /etc/resolv.conf

Press d several times to remove all lines. Press I to enter insert mode. Type:

& nameserver 192.168.0.1

(Again this is example. You should add you DNS-server.)

After you finish entering this press Esc. This will set the program in command mode. In

command mode press:

& :wq

This should do the work. To check connection use ping. If it doesn't check your

configuration again and router settings. You can use ifconfig to see OLinuXino settings.

III. Using GCC to make Hello_World

In the home folder there are some examples

& cd /home/examples

& ls

And you should see all files and folders. You can create new folder (if you want) with the

command:

& mkdir <some dir>

To see our HelloWorld program go to /HelloWorld folder

& cd /home/examples/HelloWorld

& ls

In this folder are two files:

- hello

- hello_world.c

The C file is the sourse code. Actually this is text file with .c extention. Type vi or cat

hello_world.c to view the source. You could modify the source whatever you want. After

the source is ready to compile the file use:

& gcc -o hello_world.c hello

For more complicated compiling type:

& man gcc

To execute the program:

& ./hello <some name>

The result of the execution should be:

Hello <some name>.

In the other directory /home/i2c are three examples for hardware I2C. You could compile

them using the same command:

& gcc -o <file>.c <file>
