On Windows 11 with Visual Studio 2022 I can embed Julia (version is 1.10.2) and that works fine. When I test the code inside a sandbox or on a different new computer, the initialisation fails and the error I get is :

Unable to find compatible target in cached code image.  
Target 0 (goldmont): Rejecting this target due to use of runtime-disabled features

Anybody a clue?

It is unclear to me what you are doing. Can you please elaborate what you are mean with “embed”?

It is a c++ program where I can call Julia functions.  
The line where I get the error message is

```
    jl_init_with_image(JuliaHomeDir, JuliaSysImage);

```

In my development environment it works fine. If I test the code on the same computer but in a sandbox, I get the above error message

How do you create `JuliaSysImage`? Presumably you have differences in the architectures or instruction sets between your workstation and the target, and may need to generate the sysimage for a common architecture.

The sys image is created with the PackageCompiler, I have a CJM.jl that contains the functions for the system image.

The jl script that I use to create the image is  
using Pkg  
Pkg.add(“PackageCompiler”)  
using PackageCompiler

#pkg.activate(“CJM”)  
Pkg.develop(path=“CJM”)  
PackageCompiler.create\_sysimage([:CJM],sysimage\_path=“…\bin64\Julia\bin\CJM.dll”)  
Pkg.activate(“”)

Architecture should not play a role, since when I test it in a sandbox, it is basically using the same computer hardware, only the windows environment is fresh.

And I also get this when I use jl\_init() with no parameters, when it is using its own system image.

Not sure if it is required to recreate the sys image when running on a different machine, even if I restrict those machine to be Windows 10/11 / 64bit
