maturin support on solaris sparc

[Ganeshkumhar1]

Bug Description

I work on building python's cryptography package on solaris sparc. with the latest cryptography version 43.0.1 , cryptography moved from setuptool-rust to maturin for builds.
I am unable to build maturin on solaris sparc, does it support on solaris.sparc platform? it seems latest maturin requires rustc 1.74 and newer but I am having 1.70 version.

i tried building older version of maturin like (1.4.0 or 1.5.0 ) but build is failing for me -

error[E0609]: no field domainname on type libc::utsname

How do i build it on sparc .Please suggest.

Your maturin version (maturin --version)

1.5.0

Your Python version (python -V)

3.12.6

Your pip version (pip -V)

42.2

What bindings you're using

None

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

I tried -

python3 -m pip install "maturin==1.5.0" on my sparc box.

Sorry but I don't have access to a solaris sparc box, pull requests are welcome to add support for it.
