Clean up CARGO_CFG_TARGET_FAMILY variable parsing
 2021-03-29 22:00:09 +01:00
Sergey Kvachonok ccaabe3ba5 Apply suggestions from code review: env::var() -> env::var_os() 
and fall back to load_cross_compile_from_sysconfigdata() when unset.

Sergey Kvachonok f91f795fc7 Clean up CARGO_CFG_TARGET_FAMILY variable parsing 
Match the target OS family strings exactly and provide better error messages
when CARGO_CFG_TARGET_FAMILY is not set (e.g. on wasm32).

Merge pull request #1514 from jameshilliard/cross-env-detection 
Ensure we are cross compiling when any cross env variables are set.

Sergey Kvachonok 80c747d2c0 Remove `pyconfig.h` header parsing 
The config header parsing code was supposed to be only invoked when
cross-compiling for Windows, but in reality it fails to correctly parse
the config header files shipped with the upstream Python for Windows.

Given that there are now better options for reliable cross-compiling
for Windows such as `PYO3_CROSS_PYTHON_VERSION` or the `abi3-py3*` features,
it should be OK to remove this config for v0.14.

Update the cross-compilation instructions section of the user guide.

Merge pull request #1518 from ravenexp/main 
Always use correct abi3 Python DLL name for MinGW
 2021-03-25 18:17:19 +00:00
Sergey Kvachonok a0d1c5509d Always set `Py_SHARED` when building for Windows 
Setting `PYO3_NO_PYTHON` results in an extension module built with
a different config feature set (on Windows).
Specifically, `Py_SHARED` config option gets omitted in this code path.

Maturin always sets `PYO3_NO_PYTHON` when cross-compiling abi3 extensions,
which creates a subtle configuration mismatch between `cargo build`
and `maturin build` artifacts.

Always set `Py_SHARED` when compiling abi3 extensions for Windows.

Sergey Kvachonok 2503e61c65 Always use correct abi3 Python DLL name for MinGW 
Compiling an abi3 extension module for `x86_64-pc-windows-gnu` target
links to `python3.dll` import library when `PYO3_NO_PYTHON` is set
and to `python3.Y.dll` import library when `PYO3_NO_PYTHON` is not set.

All abi3 extensions should link to `python3.dll` on Windows,
as required by

https://www.python.org/dev/peps/pep-0384/#linkage

Update the code path for the case when `PYO3_NO_PYTHON` is not set
to yield the same Python DLL import library name.

Christoph Reiter e067b32521 Support building with Mingw Python 
The DLL of the mingw Python in MSYS2 is named libpython3.8.dll:

$ python3 -m sysconfig | grep LIBPYTHON
        LIBPYTHON = "-lpython3.8"

Add another special case to in get_rustc_link_lib() to handle that case.
Afaik the mingw build doesn't support the limited ABI, so skipt that as well.

This makes all tests pass in an MSYS2 environment and lets us build
python-cryptography.
