Issue

Hi,

Apologies if the below is based on my misunderstanding.

It appears that all julia conda-forge Linux packages >v1.8.5 are missing libz.so.1 in the directory expected by libLLVM-15jl.so (or libLLVM-14jl.so for julia 1.9.x), that is, path_to_conda_environment/lib/julia. Instead, these packages rely on the libz.so.1 being present in a standard system search path (e.g. /lib/x86_64-linux-gnu/ on my machine). When this library isn't present in a standard system search path, running julia produces the error e.g.:

Unable to load dependent library /usr/local/bin/../lib/julia/libjulia-codegen.so.1.10
Message: libz.so.1: cannot open shared object file: No such file or directory

I think the relevant shared library dependency hierarchy is:

libjulia-codegen.so.1.10 depends on libLLVM-15jl.so depends on libz.so.1.

libLLVM-15jl.so is located at path_to_conda_environment/lib/julia/libLLVM-15jl.so, and has Library runpath: [$ORIGIN] (as output by readelf -d ). However, for the conda-forge julia installlibz.so.1 is located a directory higher at path_to_conda_environment/lib, and so it isn't found by libLLVM-15jl.so.

In the conda-forge julia v1.8.5 install, the libLLVM-13jl.so library has Library rpath: [$ORIGIN:$ORIGIN/..], and so it finds libz.so.1 at path path_to_conda_environment/lib.

For julia v1.10.4 downloaded directly from https://julialang.org/downloads/#current_stable_release (Generic Linux on x86, glibc binaries), libLLVM-15jl.so also only has Library runpath: [$ORIGIN], but libz.so.1 is present in lib/julia/, so it's not an issue.

This is all described in a bit more detail in the issue thread here, if it's useful.

If my understanding of the issues above is correct, would it be possible to fix this?

Thanks for any help!

Cheers,

Chris
