Can't build using x86_64-pc-windows-gcc

[Quogu]

I'm not able to build the html-py-ever example project on Windows using the x86_64-pc-windows-gcc target.

To reproduce, I did the following:

rustup default stable-x86_64-pc-windows-gnu
conda create -n test python=3.7.* setuptools-rust # This installed setuptools-rust 0.12.1
conda activate test
git clone https://github.com/PyO3/setuptools-rust
cd setuptools-rust/examples/html-py-ever
python setup.py develop

I get the following error log:

The Rust version is rustc 1.52.1 (9bc8c42bb 2021-05-09), and the example code I'm using is at revision 75787159051f133f24dbceeb143ee5ae976c7244. I'm on Windows 10 build 19042.985. My GCC toolchain version is gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0.

Would it be possible to allow setuptools-rust to successfully build against x86_64-pc-windows-gnu please?

I'm not able to help because I don't own a Windows PC, so help wanted.

Hi @Quogu, sorry it has taken me so long to investigate this.

It is possible to build using x86_64-pc-windows-gnu (I was able to build succesfully on my machine just now), but the Python you are building with must also be compiled against the x86_64-pc-windows-gnu target. I think that conda (which you were using above) uses the msvc target. This is also why you had to manually override target - setuptools_rust had detected that your Python was built using msvc.

I had to use the msys2 package mingw-w64-x86_64-python to get a successful build.

[Quogu]

Thanks for the reply, @davidhewitt!

What I don't understand is why this requirement has been added in more recent versions of setuptools-rust / PyO3 - previously we were able to build using x86_64-pc-windows-gnu against a "normal" Python install rather than needing to use a non-standard Python.

As an example, if I checkout dca1a01fc1eed1ea91cf04432240e31d78eac6d2 (the release of 0.10.6, which I'm using internally), and apply the following patch:

If I then run:

rustup default nightly-x86_64-pc-windows-gnu
conda create -n test2 python=3.7.* setuptools-rust=0.10.6
conda activate test2
python setup.py develop

It will successfully build the extension, and I'm able to launch Python and use the module successfully too.

Given that this used to work in previous versions of setuptools-rust and PyO3, this seems like a regression to me. Does that sound reasonable to you, and if so, could this issue be re-opened and investigated, please?

Thanks very much for your time.

[davidhewitt]

Thanks for the reply @Quogu.

So I've done some research and it sounds like DLLs linked with msvc (which your Python from conda will be) can be linked into binaries with the gnu target, as long as the symbols are just plain old C symbols. (From stack overflow it sounds like the issues come from different C++ symbol mangling schemes from the two compilers.)

So yes, I'm happy to consider this a regression. The original change probably came from PyO3/pyo3#1423, which supported the mingw lib name on Windows with the gnu target.

Rather than revert that PR, I'd like to provide a way to configure the DLL name to link against.

[davidhewitt]

(Or even better, I think I might be able to use sysconfig.get_platform() to automatically decide what lib name to use. I'm aiming to put something into PyO3 0.14.2 and release within the next couple of days.)

[davidhewitt]

This should be fixed in PyO3 0.14.2, which I'll put live tomorrow. PyO3/pyo3#1760

Will close again as fixed, please report back if 0.14.2 still doesn't work for you.

[Quogu]

Hi @davidhewitt,

Just to let you know, I managed to test out this change, it took me longer than I was hoping so apologies for that, but it seems good! We get far further than we did the last time we attempted to upgrade, now it's just a case of fixing up the breaking changes between 0.12 and 0.14. :)
