I am trying to build a system image for a package. The system image is built in a different machine than the one that it runs on. For efficiency reasons I want to be able to build for the cpu type of the target which is `znver3`.

Unfortunately, the resulting system image is not loadable in the target machine, resulting in:

```julia
ERROR: Unable to find compatible target in system image

```

Here is the versioninfo of the machine that created the system image:

```julia
julia> versioninfo()
Julia Version 1.9.0
Commit 8e630552924 (2023-05-07 11:25 UTC)
Platform Info:
  OS: Linux (x86_64-linux-gnu)
  CPU: 4 × Intel(R) Xeon(R) Platinum 8375C CPU @ 2.90GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-14.0.6 (ORCJIT, icelake-server)
  Threads: 1 on 4 virtual cores
Environment:
  JULIA_GPG = 3673DF529D9049477F76B37566E3C7DC03D6E495
  JULIA_VERSION = 1.9.0
  JULIA_PATH = /usr/local/julia

```

and here is the one that is supposed to use it:

```julia
julia> versioninfo()
Julia Version 1.9.0
Commit 8e630552924 (2023-05-07 11:25 UTC)
Platform Info:
  OS: Linux (x86_64-linux-gnu)
  CPU: 16 × AMD EPYC 7B13
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-14.0.6 (ORCJIT, znver3)
  Threads: 16 on 16 virtual cores
Environment:
  JULIA_DEPOT_PATH = /root/.julia
  JULIA_NUM_THREADS = auto

```

Note that `znver3` appears when in the output of `julia -C help` in both machines.

The code used to create the system image is:

```julia
julia -e 'using Pkg; Pkg.add("PackageCompiler")'
julia --project=/my_project/ -e 'using Pkg, PackageCompiler; create_sysimage(["MyPackage"]; sysimage_path="/my_project/sysimage.so", cpu_target="znver3")'

```

and the code that makes use of it:

```julia
julia -J/my_project/sysimage.so --project=/my_project 

```

Any ideas what is going wrong or how can I get more debug information? I can provide a full dockerized example, if that’s useful.

maybe try setting cpu target to generic?

Thanks, I tried that and it works, but it can have performance implications.

Actually, using `generic` results in a drastic slowdown in my use case.
