zwo-asi462mc not found

[procras2]

I have built PlanetaryImager on Archlinux and I am having trouble getting my camera to show up!

I followed the instructions to build it, which went fine and I start it from the build directory with
src/PlanetaryImager --drivers .

The ZWO ASI 462MC camera is not shown in the drop down menu.
Relevant line from .cache/PletaryImager/PlanetaryImager.log includes

DEBUG - std::shared_ptr SupportedDriver::driver() Initializing driver "./src/drivers/zwo_asi/driver_zwo_asi_imager.so"

PlanetaryImager.log

lsusb shows the camera
Bus 004 Device 003: ID 03c3:462b ASUS TEK. ASM107x

The camera works on this box with kstars, libindi_3rdparty 1.8.6-1, /usr/bin/indi_asi_ccd

When the camera is plugged in I see from the journal.

Might be because camera is too new for the asi driver included.

I think that's the case; see e.g. this thread: https://indilib.org/forum/ccds-dslrs/7452-zwo-asi462mc-error-error-connecting-to-the-ccd-16-fixed-with-new-asi-sdk.html?start=12

It seems support for 462 was added in driver version 1.15.0617 2020.6.17, while PlanetaryImager still references 1.14. (Unfortunately I'm not familiar with how this dependency is handled; it could be the case that just updating the two add_sdk calls at the beginning of https://github.com/GuLinux/PlanetaryImager/blob/master/src/drivers/zwo_asi/CMakeLists.txt will suffice.)

Thanks GreatAttractor, I did as you suggested and updated the CMakeLists.txt file to point to the newer SDK.

Line 3 of src/drivers/zwo_asi/CMakeLists.txt becomes

add_sdk(NAME ASI_Linux_Mac MAJOR 1 MINOR 15 PATCH 0915 URL "http://astronomy-imaging-camera.com/software/ASI_linux_mac_SDK_V\${ASI_Linux_Mac_SDK_VERSION}.tar.bz2" HASH_ALGO MD5 HASH ccaa3ab78ccfa5bc25fb9b18803c9629)

The SDK is downloaded, build works fine and program runs
Camera is detected and shows image when loaded, yippee!
