Error building tests on Windows 11

[sullivanmj]

When running cargo test on 8019e8a, on a Windows 11 machine, there is a build error that occurs before any tests can be executed.

I don't particularly feel the need to run the tests on my Windows machine, so please don't make this a high priority on my account. With that said, if someone makes a PR that they'd like me to test, I'm happy to help out with that.

Here's the build output, run after running cargo clean:

It turns out that I was unable to link any executable using littlefs2, once I started adding references to its API, so I decided to do a little more investigation. I tried switching toolchains from stable-x86_64-pc-windows-msvc to stable-x86_64-pc-windows-gnu. Once I got that configured correctly, I got some different error output:

I was able to get this error to go away, and successfully run all tests by updating the version of littlefs2-sys's build dependency of bindgen to at least 0.62.0. The latest released version, 0.65.1 also works. I think this means there are actually two issues here, both of which should probably be filed in the littlefs2-sys project:

• The multiple definition of strspn and strcspn linker errors that occur when using the stable-x86_64-pc-windows-msvc toolchain
• The panic that occurs when using the stable-x86_64-pc-windows-gnu toolchain, which may be fixed by updating the version of the bindgen build dependency to at least 0.62.0

I am able to work around all of the above by simply using the stable-x86_64-unknown-linux-gnu rust toolchain, version 1.69.0, via WSL.

[antonello-contini-ok]

I'm facing the same problem.
I think that the linker error caused when building for the x86_64-pc-windows-msvc target can be solved by simply not including the string.c implementation that comes with littlefs2-sys. I've tried it a bit and it seems to work, if someone is interested I can submit a PR.

[robin-nitrokey]

This should probably be fixed by this PR: trussed-dev/littlefs2-sys#15
