Running 32-bit AIR 51.2 on 64-bit systems has not been fully tested - I'm getting this message when I run my 64-bit AIR app on 64-bit NixOS and Arch

[GeneralVimes]

I built a Linux version of my game on Virtual Ubuntu 20 using the command:
~/Tools/AIR/AIRSDK_51.2.2/bin/adt -package -tsa none -storetype pkcs12 -keystore "cert/<MyCert>.p12" -storepass <myPass> -target bundle SteampunkIdleSpinnerLinux application.xml -C bin Spinner.swf data -C icons/pc . -extdir ane

The resulting file works well on the virtual Ubuntu. But when I tried to run it on 2 different computers of my friends, one with Arch, another one with NixOS, every time we received a message "Running 32-bit AIR 51.2 on 64-bit systems has not been fully tested. However, 32-bit AIR is expected to run on 64-bit systems if they have required 32-bit libraries and packages installed. The following links describe how to install or upgrade AIR 51.2 on the 64-bit versions of Ubuntu 9.10, Fedora Core 12 and openSuse 11.4"

So the question is, why is this message shown, if my app is 64-bit, not 32-bit? I also tried to add a key -arch x64, but the result was the same.

The game does not use any anes, the folder ane give in -extdir key is empty.

The app in the question: https://airapport.itch.io/farm-and-mine

If you have Linux, could you please try it on your machine, too?

Seems the same issue with some other OSes (ChromeOS, Arch, ...): #3938
Some time ago AIR had similar issue with SteamDeck: #3534

[GeneralVimes]

OK, thank you, will wait till this is fixed - BTW, on SteamDeck the game runs well, without any warning messages

Installing libxml2-legacy package helped me on Arch.

[GeneralVimes]

Cool, thank you! Hopefully this will be solved so that end user wouldn't need too install packages additional to AIR in the bundle

We've just had a look through this on a couple of platforms. Although, grabbing an arch-linux VM seemed to have all the required packages already so it just ran fine for us. On ChromeOS we found it worked after installing libnss3, so we can look at making that somethings that's loaded dynamically.

For @GeneralVimes are you able check on those non-working computers:

• in a terminal, go into the folder where you run the application from
• then do cd Adobe\ AIR/Versions/1.0
• and then share the output of ldd libCore.so | grep not which should list the 'not found' dependencies..

thanks

[ajwfrost]

Also, just looking at how to handle these .. it's unlikely to be very practical to switch everything to dynamic loading and then handle the situation where a dependency isn't actually available. So instead, I was thinking it would be better if we could update that error message so that instead of assuming you're running on a 32-bit machine, we display a message that suggests the packages that need to be installed in order for it to work?

thanks

@ajwfrost, amazing and very useful idea!
