Good point, it will fail with two cameras of the same type connected. I have to add the same naming feature as I did for SX driver... But I do believe that you don't have or at least don't use 4 same atik cameras at once
I have the following cameras: 383L+, 414ex, Titan. I also have the 16ic but I suspect that FTDI haven't produced an ARM version of their serial library.. if they have then it's possible to get around the ill fated FTDI ChipID library that seems to have died a death as long as the user knows their camera identifier.
One of the 300mm is f4 but the other is f5.6 so I think I may just stick to the f4..
I think we can put this down as as work around using the existing armhf binaries.
edit .bashrc or /etc/profile for a global change and then add something like export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my/armhf/directory/with/32bit/libcfitsio
I've also noted that when building the indi system from scratch that you'll need to add /usr/lib to the LD_LIBRARY_PATH too.
I've posted a couple of images with a full arm v8 64bit build (indilib, 3rdparty drivers and kstars) and although the eqmod and focuser etc are all running 64bit the indi driver process for the ATIK support has been the arm v7 32bit (armhf) binary straight from the cloud makers site.
