\*\* environment: linux with Version 1.11.3 (2025-01-21) of julia and the latest version of PackageCompiler.jl

I started studying the PackageCompiler.jl documentation and tried to reproduce the example [sample](https://julialang.github.io/PackageCompiler.jl/stable/apps.html). More precisely, I ran:

```julia
[alex@desk ~]$ cd .julia/packages/PackageCompiler/UbaS4/examples
[alex@desk examples]$ julia
julia> using Pkg
julia> Pkg.generate("MyApp")
julia> exit()
[alex@desk ~]$ julia -q --project
julia> using PackageCompiler
julia> create_app("MyApp", "MyAppCompiled")

```

However, I received:

From what I understand, it seems to be a problem in the PackageCompiler package… Since I’m still new to julia, I would like to check if my assumption is correct? (Problem with the PackageCompiler package) If that’s the case, I’ll report it in the project’s Issues…

Or is it just a beginner’s mistake?

I tried this example and it compiled just fine:

Okay, I must be doing something wrong… Thanks for the feedback.

So… I used this sequence of steps:

```julia
julia
using Pkg
Pkg.generate("MyApp")
exit()
julia -q --project
using PackageCompiler
create_app("MyApp", "MyAppCompiled")

```

The error remains…

Did I forget something? If so, what was the sequence of steps you used?

Also, the version of what I’m using is: PackageCompiler v2.2.0. Does it match yours?

Hm, I did not

```julia
using Pkg
Pkg.generate("MyApp")
exit()

```

because MyApp exists.

I just

```julia
cd /tmp
cp -r ~/.julia/packages/PackageCompiler/UbaS4/examples/MyApp .

julia -q --project

julia> using PackageCompiler
julia> create_app("MyApp", "MyAppCompiled")
julia> exit()

```

I think I’ve figured out the problem… During this week, I tried to reproduce the problem on another OS. So, I followed the same steps I described here in the post using PoP!\_OS 22.04 LTS. In this case, the problem didn’t occur.

My main system is ArchLinux. Since it’s been installed for over two years, I decided to try to reproduce the problem on a “clean install”. As a result, this time Julia didn’t even start. The error reported was:

```julia
$ julia
ERROR: Unable to load dependent library /home/alex/.julia/juliaup/julia-1.11.3+0.x64.linux.gnu/bin/../lib/julia/libopenlibm.so
Message:/home/alex/.julia/juliaup/julia-1.11.3+0.x64.linux.gnu/bin/../lib/julia/libopenlibm.so: cannot enable executable stack as shared object requires: Invalid argument

```

With a quick google search, I found this blog post: [https://discourse.julialang.org/t/error-cannot-enable-executable-stack-when-starting-julia-solved/125655](https://discourse.julialang.org/t/error-cannot-enable-executable-stack-when-starting-julia-solved/125655)

It describes the problem in more detail… But in short, it may have something to do with a glib update (see [https://github.com/JuliaLang/julia/issues/57250](https://github.com/JuliaLang/julia/issues/57250)) for more details…)

The suggestion that worked on (clean Arch Linux install) was:

```julia
git clone https://aur.archlinux.org/execstack.git
sudo pacman -S elfutils (if you don't have it installed)
cd execstack/
makepkg
sudo pacman -U execstack-....pkg.tar.zst
execstack -c /home/user/.julia/juliaup/julia-1.11.3+0.x64.linux.gnu/bin/../lib/julia/libopenlibm.so

julia
] + add PackageCompiler
using Pkg
Pkg.generate("MyApp")
exit()

julia -q --project
using PackageCompiler
create_app("MyApp", "MyAppCompiled")

```

As soon as possible, I’ll test it on my main system (Arch ~2 years old) and update the post.

\*Conclusion: It seems to have nothing to do with PackageCompiler.jl, but I think it’s better not to change the post name because others may have similar problems…
