ImageView not precompiling -- UndefVarError

General Usage
1

I have been unable to precompile ImageView from midway in the 1.9.0 dev series to now 1.10.0-Dev.38.
In all attempts there is a common error flagged:

ERROR: LoadError: UndefVarError: #imshow##kw not defined

It would be cool to have my own cheap Photoshop, below are the woeful messages generated:

I hope this is an easy fix.
I also am very excited about JuliaCon 2022!

Indeed, but perhaps you could try Julia 1.8 for now. I don’t know whether all packages have been updated for 1.9 and 1.10 yet.

Thanks, I am not so unstable that running stable is a problem.
Now, will running the latest stable version screw up any chance of a dev release
being able to precompile packages correctly?
Is it possible to have ./julia for the stable release and for instance specify
./julia-dev for a development release?

I’m not quite sure what this means… but according to “semver” (semantic versioning) Julia 1.9 should run code that runs OK on Julia 1.8.

But, as I understand it, a new version of a package that relies on new features introduced in 1.9 will not even be available for loading on 1.8 - because its Project.toml file will contain the line

julia = "1.9"

so you wont be able to add that version to a 1.8 environment.

@cormullion
Thanks for your reply, I saw it first the day before yesterday in an email notification. The email had a reply button which I selected to respond but at least for me, the reply went to the bit bucket.
I am running stable for ImageView. I’ll compile a dev release every few days to see if the missing variable error gets rectified.
On account of that error I am leaving this topic open.
Again, thanks for your time and patience!
