stack-shim's Issues

wrong ELF class: ELFCLASS32

Hello,

Many thanks for publishing this on GitHub!

I am running Debian GNU/Linux 12 (bookworm) amd64 and I was at a loss on how to fix the eschalon segfault until I read this!

What I did is as follows:

$ pushd /tmp
/tmp ~
$ git clone https://github.com/darktjm/stack-shim.git

And then the launch menu appears and the sound starts playing!!!

Any ideas why I get those wrong ELF class errors? Do you get them too? Are they harmful?

Thanks again,
