Rustc 1.78 Undefined Reference to getauxval

[tustvold]

Code

I'm afraid the reproducer is in a fairly chunky docker image, with the wonder that is conda, but I suspect there might be a more generic issue here perhaps??

$ docker run --rm  -it --entrypoint bash apache/arrow-dev:amd64-conda-integration@sha256:16d358c1fe5f333d18bae2a648a780481148ad934fe85cf4a3be1b11f3453998

Then within the image

If you downgrade to version 1.77 compilation works as expected

The version of glibc does not appear to be especially old

Version it worked on

It most recently worked on: Rust 1.77

Version with regression

rustc --version --verbose:

cargo 1.78.0 (54d8815d0 2024-03-26)

This appears to have been introduced by #113525 FYI @workingjubilee

[workingjubilee]

@tustvold getauxval is in glibc 2.16 and we demand a higher minimum glibc than that. I am struggling to understand how it is possible for you to link our code at all given we pervasively reference other libc symbols in the stdlib. The only thing I can imagine is that a minimum-qualifying libc is not actually linked in (somehow, yes I see the ldd --version invocation, it's possible something else actually gets found on the PATH... somehow...?) and you essentially lucked out before.

[workingjubilee]

Yeah, the problem is in what you've done with conda. apache/arrow-rs#5719 (comment)

Our glibc minimum is 2.17 and you have not followed the directions to cause conda to use the required glibc for linkage. You need to change the sysroot_linux-64 version. We raised the glibc requirements past 2.16 in 2022.
