Using `JuliaC` on Centos7

[bmxam]

Hi,

I'm trying to compile a julia script (just a simple helloworld, like in the JuliaC repo) using JuliaC on a Centos7 machine. I know Centos7 is EOL, but this is a constraint for an old HPC cluster.

As far as I know, the main constraint with Centos7 is the GLIBC version : 2.17.

What I've tried so far (using Docker images):

• centos:7 + download julia 1.12.4 + app add JuliaC + juliac (...)
• centos7-gcc13 + git clone julia (v1.12.4) + compile (USE_BINARYBUILDER=1) + app add JuliaC + juliac (...)
• centos7-gcc13 + git clone julia (v1.12.4) + compile (USE_BINARYBUILDER=0) + app add JuliaC + juliac (...)

juliac manages to compile an executable, but when I try to run this executable, the following error is raised:

error: runtime auto-initialization failed due to bad sysimage lookup
       (this should not happen, please file a bug report)

Do you have any clue on how to solve this? Is it even possible (with the constraint GLIBC = 2.17)?

Thank you!

I also tried with devtoolset-9 gcc on CentOS 7, same error.

Running under gdb, I see this dlopen returns NULL and running dlerror prints "/build/bin/app_test_exe: cannot dynamically load executable"

Running the executable on another machine (pop os 22.04, glibc 2.35) works fine. So I guess something changed in how dlopen works?
