Linux binaries (WSL Ubuntu) made by PackageCompiler.jl hangs (\>1hr) while maxing out RAM. Windows binaries work though. How to debug?

I guess you need to tell us more about the code that you compiled to get a useful answer.

It’s a FDTD simulator [GitHub - paulxshen/Luminescent.jl](https://github.com/paulxshen/Luminescent.jl)
Windows binaries work.
Linux binaries hangs now but worked few months ago.
Tried couple different Linux machines to same effect.
My entry point returns immediately on empty ARGS - still hangs in this case - so it’s not even executing my code.

I guess I can try using older PackageCompiler when it last worked. But still nice to know what’s causing the current issue

Can you:
1. provide the output of `using Pkg; Pkg.status()` ?
2. provide the code you use to run PackageCompiler ?

Tried incremental=false didn’t work. Tried rolling back to 2.1.17 but got some jll error on julia 1.11 - not worth debugging.
Odd why compiling on windows works…

One thing I had to do was to add `include_transitive_dependencies=true,`:
```julia
PackageCompiler.create_sysimage(
[:Dierckx, :StaticArrays, :Parameters, :NLsolve, :DocStringExtensions, :Sundials, :KiteUtils,
:KitePodModels, :AtmosphericModels, :OrdinaryDiffEqCore, :OrdinaryDiffEqBDF, :OrdinaryDiffEqSDIRK,
:ModelingToolkit, :DSP, :JLD2, :Colors];
sysimage_path="kps-image_tmp.so",
include_transitive_dependencies=true,
precompile_execution_file=joinpath("test", "test_for_precompile.jl")
)
```
Furthermore, if you want more support I am afraid you have to provide a “minimal working example” that allows others to reproduce your problem, see: [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757)

Thanks I think include\_transitive\_dependencies=true is default - anyways I tried it and didn’t work. Also tried w/o luck incremental true. MWE is good practice but IDK if it has any additional useful info here. Meanwhile I interrupted ^C when it hangs and got:

Because it’s hanging even on a dummy function that returns 0, I assume it’s stuck deserializing the sysimage? There were couple other github issues on apps hanging but no responses. .

Did you try if it works with Julia 1.10?

Thanks for trying Julia 1.10.6 !
Now we only need a reproducable MWE (minimal working example) so that someone else can reproduce your problem.

CUDA is problem. see my new thread [CUDA app by PackageCompiler hangs at runtime on Ubuntu / Debian](https://discourse.julialang.org/t/cuda-app-by-packagecompiler-hangs-at-runtime-on-ubuntu-debian/124995)
