PackageCompiler with VS Code

Tooling VS Code
1

I’ve been making custo system images like so

using PackageCompiler
create_sysimage([:StatsPlots,:LinearAlgebra,:Calculus, :MCMCChains, :StatsPlots, :Distributions, :BenchmarkTools,
:Tullio, :LoopVectorization], sysimage_path="JuliaSysimage.dll", precompile_execution_file="to_compile.jl")

This works like a charm when starting Julia with the appropriate flags. However, I was under the impression that VScode would automatically find the sys image when it is saved as “JuliaSysimage.dll” in the folder with my project.toml. I lauch the REPL in VS Code from the desired folder. It automatically uses the correct environment. But It is very clear from TTFP that I’m not using my custom system image. Not sure what I’m doing wrong.

This is on Windows 10, Julia 1.6.1, PackageCompiler 1.2.6, and up to date VS code + Julia extension.

Thanks

Also. Is there a way to specify the sysimage you want to use with VS code?

There is a setting in the extension that enables this and that is off by default.

Hello.
If you have multiple sysimages, after turning the setting in the Julia extension on, how does VS Code ‘know’ where to look for the right/wanted .so file?

It looks for the sysimage file in the same folder where the Manifest.toml is.
