Hello, again.

And many thanks for answer, Erik.

After that:

cd compile/libv4l-0.4.0
wwarlock@mdv2k8 ~/compile/libv4l-0.4.0 $ make all

make: *** [export] Error 1

One error because this is not first export. But, it does not matter.


Then i'm exporting LD variables how writen in documentation.

And when i'm trying to use any capturing program (i.e. cheese, vlc, 
xawtv) my laptop just hangs.

Nor Ctrl+Alt+F1, nor Ctrl+Alt+SysRq - combinations does not working.
Only Caps Lock is flashing.

Doctor, please say me, is my patient will be alive? ))

With best regards,
Dmitriy.
