Crate python3_dll_a
source · [−]Expand description
Standalone python3.dll
import library generator
Generates import libraries for the Stable ABI Python DLL for MinGW-w64 cross-compile targets.
See https://docs.python.org/3/c-api/stable.html for details.
This crate does not require Python 3 distribution files to be present on the cross-compile host system.
Example build.rs
script
The following script can be used to cross-compile Stable ABI PyO3 extension modules for Windows:
fn main() {
if std::env::var("TARGET").unwrap() == "x86_64-pc-windows-gnu" {
let libdir = std::env::var("PYO3_CROSS_LIB_DIR")
.expect("PYO3_CROSS_LIB_DIR is not set when cross-compiling");
python3_dll_a::generate_implib(&libdir)
.expect("python3.dll import library generator failed");
}
}
A compatible python3.dll
import library will be automatically created in
the directory pointed by PYO3_CROSS_LIB_DIR
environment variable.
Example cargo build
invocation
PYO3_CROSS_LIB_DIR=target/python3-dll cargo build --target x86_64-pc-windows-gnu
Functions
Generates python3.dll
import library directly from the embedded
Python Stable ABI definitions data.
