I compiled it with command where lpt.c is source code and lpt is program name compiled.

gcc lpt.c -O2 -o lpt

I used LED with 550 ohms resistor in series and soldered it between pin 2 and 20 to test out this program.

1. I located where is my profile at windows machine. In my case I found it

Q:\Documents and Settings\my_win_username\Application Data\Thunderbird\Profiles\

There was folder named something like ks7f7j02.default with random hash at beginning.That was my profile.

2: I located profiles folder in my kubuntu 8.10, I found it at

/home/my_linux_username/.mozilla-thunderbird/

3. I copied my profile folder with same name in there.

4. I opened file

/home/my_linux_username/.mozilla-thunderbird/profiles.ini

I cant remember what was there before, but I eventually it contained these lines.

[General]
StartWithLastProfile=1

[Profile0]
Name=default
IsRelative=1
Path=ks7f7j02.default

Where Path= is important. You must type your profiles folder name there.

After this I started my thunderbird and I had my account setup in linux. Also it might alert error something like unable to find binary component. This is produced by thunderbird because it does not find your plugins that might be installed when you worked with windows.

In first comment is a much better solution for it. Just copy the all thing.
