SObjs libmng.so.1 is missing, required by 8SVX datatype.

So, my notification sound in AmIRC mysteriously disappeared. Seems its because the AK-8SVX datatype (in Enhancer 2.2) requires libmng.so.1: "Failed to find canonical name for " it says when double-clicking AK-8SVX.

So, where do I find that one?

Is it perhaps part of another SO?

libmng seems to be a graphics library. I wonder what a sound datatype uses it for?

@Deniil

Are you sure that's where the message is coming from? Both ListDynDep and readelf -d indicate that AK-8SVX.datatype has no dynamic section, and therefore does not require any shared objects.

Double-clicking a datatype's icon normally runs "C:AddDataTypes", which adds the associated datatype to the system. But I notice that the default tool for the AK-8SVX icon is "MultiViewer:MultiViewer", which isn't really what you want (though MultiViewer doesn't use any shared objects, either).

Perhaps your default tool somehow got set to some other program?

Apparently the JNG.datatype has a ref to this SO. I have JNG and MNG.datatypes. Have no idea what they are for

Maybe MultiViewer tried to load the datatype (icon?) as a PNG image, which might use one of those?

sounds like your MNG.datatype descriptor has matched against some of your ordinary png files.

Multiviewer will display a GUI when displaying sound files that has png elements in it.

@Deniil

JNG and MNG are graphics formats (MNG is animated... I think). They aren't common. If I can locate the code and it's easy to do I'll rebuild them statically.

It looks like I uploaded it back in 2020 for some reason.

One of the descriptors replaces the PNG datatype, so that might be in use, and reverting to the original descriptor is probably sensible.
