Hi Helge,
Sorry, I should have given you some more background info on those drivers and on how symlinks work on linux. When you issue this ls statement then you can see that all but one atik drivers are in fact symlinks to this one driver file:
$> ls -al /usr/lib/x86_64-linux-gnu/libatik*
lrwxrwxrwx 1 root root 19 Mar 9 14:46 /usr/lib/x86_64-linux-gnu/libatikcameras.so -> libatikcameras.so.2
lrwxrwxrwx 1 root root 23 Mar 9 14:46 /usr/lib/x86_64-linux-gnu/libatikcameras.so.2 -> libatikcameras.so.2.2.5
-rw-r--r-- 1 root root 4247608 Mar 9 14:46 /usr/lib/x86_64-linux-gnu/libatikcameras.so.2.2.5
lrwxrwxrwx 1 root root 12 Mar 9 14:46 /usr/lib/x86_64-linux-gnu/libatik.so -> libatik.so.2
The arrows, denoted by "->" mean it is a symlink. So in fact the only symlink needed is to the /usr/lib/x86_64-linux-gnu/libatikcameras.so.2.2.5 file. HOWEVER the filename will change with future updates of the driver and that is why the other symlinks exist.
I executed your symlink command and this is the result:
$> sudo ln -s /usr/lib/x86_64_linux_gnu/libatik*.* /usr/local/lib
$> ls -al /usr/local/lib/libatik\*.\*
lrwxrwxrwx 1 root root 36 Apr 5 18:21 '/usr/local/lib/libatik*.*' -> '/usr/lib/x86_64_linux_gnu/libatik*.*'
So you in fact created a symlink to a non-existent file and that is why it still doesn't work.
In short, please execute the symlink command as I stated before:
sudo ln -s /usr/lib/x86_64_linux_gnu/libaltaircam.so /usr/local/lib
and it should work. Actually you'll need to delete the old symlink with
sudo rm /usr/local/lib/libatik\*.\*
Note the two back slashes which are ESSENTIAL to make the command work!!!!
Please also note that with every update of the atik driver you will need to check if the symlink still points to an existing file. If it doesn't and you don't check, you will notice because you return to the same problems
The atik driver maintainer (is that Atik themselves?) should adhere t the INDI standard that the drivers should be in /usr/local/lib OR should add a command to automatically create the symlink when installing the package and actually remove the old one when upgrading the package. fortunately the way apt and dpkg work on Debian based Linux distributions, of which Ubuntu is one, makes this very well possible and actually easy to implement.
Let me know please if it works once you have done all of this
CS, Wouter
