Can't build on Windows

[pansila]

Are there any instructions to build it on Windows?

1. I run 'cargo build' but failed with wrapper.h:1:10: fatal error: 'libuvc/libuvc.h' file not found.
2. I download libuvc source code and extracted to uvc-src/source, ran 'cargo build' in uvc-src, but end up with the error:

  error occurred: Command "C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.27.29110\\bin\\HostX64\\x64\\cl.exe" "-nologo" "-MD" "-Z7" "-Brepro" "-I" "d:\\workspace\\libuvc-rs\\target\\debug\\build\\uvc-src-4dd37a42ddbc29e6\\out\\include" "-I" "d:\\workspace\\libuvc-rs\\target\\debug\\build\\libusb1-sys-aaea21a84a91340c\\out\\include" "-Fod:\\workspace\\libuvc-rs\\target\\debug\\build\\uvc-src-4dd37a42ddbc29e6\\out\\source/src/ctrl.o" "-c" "source/src/ctrl.c" with args "cl.exe" did not execute successfully (status code exit code: 2).

This crate is using cargo features, you can build a static/vendored binary with cargo b --features vendor. The sources can be downloaded using git submodule --init --recursive instead of extracting an archive

@mulimoen Still getting the error.

@pansila That error is a bit mysterious, could you try getting a more verbose output with e.g. cargo b --features vendor -vvv?

[mulimoen]

If you don't have libusb installed you might have to configure libusb to also be vendored. You can do this by adding features = ["vendored"] under uvc-src/Cargo.toml.

<sys/time.h> can not be found. It's not in the MSVC toolchain. A similar one is C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\ucrt\time.h. I can only find it in the C:\msys64\mingw64\x86_64-w64-mingw32\include\sys\time.h, but building it against mingw's headers doesn't work.

I'm afraid using this for windows is not possible at the momen. The c library (which this crate wraps) does not support windows: https://github.com/libuvc/libuvc/issues/136. Workarounds exists, see that issue. If you install a functioning libuvc, it should be possible to link to system uvc, but I do not have any windows experience, so I can't help you much there.

[pansila]

Thanks for your quick reply. Looks libuvc has no plan to support Windows.

https://github.com/pupil-labs/libuvc You will have better lucks with the above libuvc fork for Windows.
