[sigc] Alian doesnt work ?

[Jeffry Molanus <Gila home nl>]

Hi there,

I have a small problem compiling the alian tutorial from the website.

When i'm compiling i get:

/tmp/ccb4OyYu.o(.text+0x47): In function `main':
: undefined reference to `AlienDetector::AlienDetector[in-charge]()'
/tmp/ccb4OyYu.o(.text+0xc0): In function `main':
: undefined reference to `AlienDetector::run()'
collect2: ld returned 1 exit status


Thx in advance!
