State of Windows support

[fanc999]

Hi,

I was able to compile the latest GIT checkout with Rust 1.66.0 with the stable-x86_64-pc-windows-msvc toolchain, along with Visual Studio 2015, however:

• I had to drop the following lines, for pretty clear reasons:

 fn main() -> anyhow::Result<()> {
-    #[cfg(not(unix))]
-    {
-        return Err(anyhow::anyhow!("Add support for target platform"));
-    }

• The program panicked on startup, with RUST_BACKTRACE=full I had:

%HOMEPATH%\.cargo\bin\glide e:/mp3/BeyondBeauty/4.mp3
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: BoolError { message: "Failed to get cast value to a different type Unexpected None", filename: "C:\\Users\\fanc999\\.cargo\\registry\\src\\github.com-1ecc6299db9ec823\\glib-0.15.12\\src\\object.rs", function: "glib::object", line: 2353 }', C:\Users\fanc999\.cargo\registry\src\github.com-1ecc6299db9ec823\glib-0.15.12\src\object.rs:2359:42

Oh, I was running (all built with Visual Studio 2015 or 2017):

• gtk+-3.24.36
• gdk-pixbuf-2.42.10
• cairo-1.17.6
• pango-1.50.12
• harfbuzz-6.0.0
• gstreamer 1.20.4 (with base, good, bad and ugly plugins)
• glib-2.74.4

[philn]

That looks like an issue in the gtk-rs bindings?

[philn]

Can you check again? git master was ported to GTK4 and Adwaita. Using GStreamer 1.22 would be good too.
Ideally I suppose we could somehow make a windows installer bundling all the deps, but I have no idea (or interest, sorry) how to do that.

Hi, I was just testing compiling on Windows. I was getting some error which I fixed by downloading pkg-config binary and putting it into path, but then I got stuck on not having gio-2.0:

  The system library `gio-2.0` required by crate `gio-sys` was not found.
  The file `gio-2.0.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `gio-2.0.pc`.

Apparently installing GLib should fix that, but I didn't manage to figure out where to download that from.

[philn]

Have you tried this? https://www.gtk.org/docs/installations/windows/

[philn]

Also, https://gtk-rs.org/gtk4-rs/stable/latest/book/installation_windows.html

[sdasda7777]

Thanks for the replies! I did find the first page, but it's too complicated for me :/ Does it not have an installer?

[philn]

I really have no idea about this windows stuff :( Maybe some of the tooling/packaging done by GPS can be reused though, see https://gitlab.freedesktop.org/dabrain34/GstPipelineStudio/
