can't build on windows #28

asuper0 · 2022-08-05T09:25:27Z

My Environment:
Windows 10 1809
Visual studio 2022
vcpkg commit 6a29f32
libvpx & opus installed with vcpkg:
libvpx:x64-windows 1.11.0#1
opus:x64-windows 1.3.1#6

I have tried some ffmpeg binding crates with vcpkg and succeed, so the vcpkg settings would be correct.
when I run "cargo build", it shows

Thank you for your issue!
It seems that the problems are located in vpx-rs and opus-rs which are not able to retrieve the dynamic libraries on Windows. Could you try to build the two crates independently and see if they work on Windows?

Thanks for your reply! As you see, its the same.

asuper0 · 2022-08-05T10:05:00Z

BTW, I'm trying to build static version of libvpx & opus by vcpkg. It will take some time.

Luni-4 · 2022-08-05T10:41:22Z

Thank you for your effort!

As fast solution, we can try to replace metadeps with system_deps like we already do for aom. We just need to implement these changes

Otherwise we can add a build feature which builds the libraries from scratch and then links them, but this is one is much difficult to have

asuper0 · 2022-08-05T14:58:45Z

I tried to use the system_deps but failed. I also found vpx_rs is using the system_deps as well as aom_rs, so I tried them both, and failed again.

I use vcpkg_cli to check the aom lib :

I noticed that the system-deps github page says "For now only pkg-config dependencies are supported, but we are planning to gdesmott/system-deps#3 at some point." . So that would be the problem. I'm not familiar with pkg-config. It seems that pkg-config in windows should use mingW, which is not compatible with msvc. So I'd prefer use vcpkg rather than pkg-config.

I found that rusty_ffmpeg and rust-ffmpeg-sys use another build system which support vcpkg. Could you please take a look at that?

Luni-4 · 2022-08-05T16:51:11Z

Yeah, you're right, I haven't noticed that part, I thought system-deps was a cross-platform crate.

rust-ffmpeg-sys uses the vcpkg crate to find dependencies. Here adds the library to Cargo.toml and here and here implements that. We can add that code to our three -sys crates to find vcpkg dependencies.

Unfortunately, I will be out of town for one week, so I won't be able to work on that, but you can try to verify whether it works locally for you. If something happens, feel free to open a PR in each of the three repos, I will be happy to review them when I come back.

asuper0 · 2022-08-05T17:16:13Z

Thanks for your advise. I'll try to solve it, though I am new to Rust 😅

Luni-4 · 2022-08-05T17:20:01Z

Welcome to Rust! Oh, no problem. take your time! 😃

lu-zero · 2022-08-05T21:27:47Z

I'd argue that either vcpkg gets reimplemented to remove the telemetry or maybe not everybody would be cool with it.

(also http://pkgconf.org/ exists)

Luni-4 · 2022-08-05T22:12:47Z

Another solution could be to build on Windows through msys2, so we don't have any telemetry, and the packages can be installed easily. It should be sufficient installing msys2 and the mingw target with rustup toolchain install stable-x86_64-pc-windows-gnu

To install packages:

vpx
opus

To build: cargo build --target x86_64-pc-windows-gnu

asuper0 · 2022-08-09T10:40:55Z

I just created two PR for vpx and opus. The code may not so rusty but works.

for aom, I meet a type convert error https://github.com/rust-av/aom-rs/blob/master/src/encoder.rs#L100-L102 . The aom-sys require aom 3.0.0 but my aom in vcpkg is 3.2.0, and they differ in the type of aom_image.cp, aom_image.tc, aom_image.mc. While my ffmpeg depends on aom, rebuilt them will take a long time. So, I would not try to fix aom-rs.

I need to say its important to me to make these package support for vcpkg, because all my dev env are built on it.
I also trid the msys2 solution, but don't know where to continue after installing the toolchina whit rustup toolchain install stable-x86_64-pc-windows-gnu

Thanks for your PRs @asuper0! I'm going to review them as soon as possible!

For what concerns aom, please open an issue on aom repository about the errors you have found. I suppose the first one is a clippy error, while the second one is related to a missing update. Feel free to open PRs if you want, I would like to add dav1d and aom decoders in these examples as well.

I propose to hide vcpkg behind a Rust feature, in this way it's not an official solution, so @lu-zero statement is respected, but at the same time you can use your dev env. You can add this feature, we can call it vcpkg, to your PRs and try if it works on Windows with cargo build --feature vcpkg.

Have you installed msys2? If you have, try to install opus package with this command pacman -S mingw-w64-x86_64-opus and then try to build opus-rs with cargo build --target x86_64-pc-windows-gnu. vpx-rs is analogous but with the package pacman -S mingw-w64-x86_64-libvpx
Let me know if it works!

asuper0 · 2022-08-16T03:11:45Z

@lu-zero #rust-av/opus-rs#27
You're right. I apologize for my hesitation when you suggest to use the pkg-config. I built the example without changing any code by simply installing a pkg-config tool and setting the PKG_CONFIG_PATH to vcpkg\installed\x64-windows\lib\pkgconfig. Everything works perfectly except the VERSION string in opus.pc is "0", and I modified it myself.

To @Luni-4 , thanks for the help. While the system_deps with pkg-config works well, my PR may be closed, it depends on you. Maybe a build tutorial for windows is good for rust-av or other projects.

@lu-zero #rust-av/opus-rs#27 You're right. I apologize for my hesitation when you suggest to use the pkg-config. I built the example without changing any code by simply installing a pkg-config tool and setting the PKG_CONFIG_PATH to vcpkg\installed\x64-windows\lib\pkgconfig. Everything works perfectly except the VERSION string in opus.pc is "0", and I modified it myself.

Probably the vcpkg people should be made aware of the problem, they seem fairly responsive from what I saw in the system-deps discussion.

A good tutorial for windows would be great, we have less experience with the platform so your help would be precious :)

Great that you solved your problem @asuper0! Can you please add here the series of steps you have used to compute the examples with vcpkg? I want to add that to the CIs of the three repositories, in this way CI works as documentation too for other people. Thank you!

Download pkg-config-lite . I find this on stackoverflow ;
Extract it, add the bin folder to your $PATH ;
Add your_vcpkg_root\installed\x64-windows\lib\pkgconfig to $PKG_CONFIG_PATH . (noticed, x64-windows is depens on your config) ;
Restart or relogin to make the environment variables work .
In the project dir, run cargo build.

It seems it is possible to install pkg-config-lite through chocolatey. Perhaps we can skip steps 1 and 2. May you please also tell me how to install packages through vcpkg?

asuper0 · 2022-08-16T10:07:29Z

vcpkg make .pc files automatically when your run vcpkg install some_package, and all of them are at the same location. Here is mine:

It is annoying that pkgconf.org doesn't offers builds otherwise it would be an even nicer alternative :/

Luni-4 · 2022-08-18T07:40:58Z

@asuper0
Could you please write down the commands to install opus and vpx? Because it seems I have problems with the packages

asuper0 · 2022-08-18T08:21:18Z

What kind of problem?
With $VCPKG_DEFAULT_TRIPLET set to x64-windows :

vcpkg install opus
vcpkg install libvpx

or without the environment variable :

vcpkg install opus:x64-windows
vcpkg install libvpx:x64-windows

Notice that vpx is named libvpx. Your can use vcpkg search vpx if you are not sure the name.
