Can't cross compile to windows "cannot set a minimum Python version 3.8 higher than the interpreter version 3.7" #2436
Description
Bug Description
I have a crate that I'm trying to cross compile to windows using:
maturin build --target x86_64-pc-windows-gnu --release
and it fails with

💥 maturin failed
Caused by: Failed to build a native library through cargo
Caused by: Cargo build finished with "exit status: 101": `env -u CARGO PYO3_CONFIG_FILE="/home/xxxx/xxxx/target/maturin/pyo3-config-x86_64-pc-windows-gnu-3.7.txt" "cargo" "rustc" "--target" "x86_64-pc-windows-gnu" "--message-format" "json-render-diagnostics" "--manifest-path" "/home/xxxx/xxxx/xxx-client-python/Cargo.toml" "--release" "--lib"`
Some relevant parts of the Cargo.toml:
pyo3 = { version = "0.23", features = ["extension-module", "generate-import-lib", "abi3-py38"] }
pyo3-async-runtimes = { version = "0.23", features = ["tokio-runtime"] }
It seems very misleading, because it mentions python3.7, when I'm not using or specifying that version anywhere. It seems that while it says Not using a specific python interpreter (automatically generating windows import library) it's using 3.7 to some extent under the hood. The same configuration used to work with a lower version of PyO3, I'm not sure if I should report it there.
Your maturin version (maturin --version)
1.8.1
Your Python version (python -V)
Python 3.12.3
Your pip version (pip -V)
pip 24.0
What bindings you're using
pyo3
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
maturin build --target x86_64-pc-windows-gnu --release
