Steps to Reproduce the Problem
Hi @antonie3007,
Could you run:
mix clean --deps
V=1 mix compile
I think that you may have CFLAGS or LDFLAGS defined in your environment and the value is getting used. The V=1 part will show what's being passed to gcc.
Hi @fhunleth
Here is the result.

@fhunleth
As far as I can see the CFLAGS and LDFLAGS are NOT defined in my environment echo $CFLAGS and echo $LDFLAGS give an empty response
Regards Antonie,
Hmm. My next guess is that this is coming from a compilation mismatch between the defaults (which Circuits.UART is getting) and whatever Erlang is compiled with.
The way to figure that out is by removing -L/usr/lib64/erlang/usr/lib -lei from the link step and trying it again:

You'll get errors about ei library functions not being found, but the ELFCLASS64 one should go away.
If this happens, then I'm not sure why. Maybe some google searches could lead you to some hints? I almost exclusively use asdf to install Erlang, so if that's an option, then I'd probably give that a try.
Hmmmmm,
Retrying it with the command you send me stil get's me the error error loading plugin: /usr/libexec/gcc/x86_64-redhat-linux/13/liblto_plugin.so: wrong ELF-class: ELFCLASS64
I've tried installing Erlang and Elixir with asdf but I get the error:
checking whether the C compiler works... no

This seems like the same error of the liblto_plugin.so

Hi @fhunleth ,
Could this be an issue with Fedora 38 because it had an GNU Toolchain Update (gcc 13.0, binutils 2.39, glibc 2.37, gdb 12.1) in relation to the previous version of Fedora
asdf install of erlang and elixir and compile circuits.uart is working perfectly on Fedora 37
Gr. Antonie
