How to build it with gtk4-layer-shell feature?

[murlakatamenka]

Hi, thanks for the interesting project!

I have issue building it on my Arch, here is what I tried:

git clone --depth 1 <repo>
cd mixxc

cargo build --release --features=Sass,Wayland

output:

   Compiling gdk4-sys v0.7.2
   Compiling gsk4-sys v0.7.3
   Compiling gtk4-sys v0.7.3
   Compiling gtk4-layer-shell-sys v0.1.2
The following warnings were emitted during compilation:

warning: `PKG_CONFIG_ALLOW_SYSTEM_CFLAGS="1" "pkg-config" "--libs" "--cflags" "gtk4-layer-shell-0" "gtk4-layer-shell-0 >= 1"` did not exit successfully: exit status: 1

error: failed to run custom build command for `gtk4-layer-shell-sys v0.1.2`

Caused by:

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

While submitting the issue, I've realized I'm missing gtk4-layer-shell shared, I've installed it via such PKGBUILD:

# Maintainer: Shengyu Zhang <la@archlinuxcn.org>
# Contributor: Brett Cornwall <ainola@archlinux.org>
# Contributor: Adrian Perez de Castro <aperez@igalia.com>

pkgdesc='A library to create panels and other desktop components for Wayland using the Layer Shell protocol and GTK4'
pkgname=gtk4-layer-shell
pkgver=1.0.1
pkgrel=1
arch=(x86_64 aarch64)
license=(MIT)
url="https://github.com/wmww/gtk4-layer-shell"
depends=(
    "gtk4"
    "wayland"
)
makedepends=(
    "gtk-doc"
    "gobject-introspection"
    "meson"
    "ninja"
    "valabind"
    "python"
)
source=("$pkgname-$pkgver.tar.gz::$url/archive/v$pkgver.tar.gz")
sha256sums=('f7b8d352065a540d4cb7b0cbfdeb2c2efea55b57cfb717de5c880fde41e65cb1')

build() {
    meson setup \
          --prefix=/usr \
          --wrap-mode=nofallback \
          --buildtype=plain \
          -Dtests=true \
          -Ddocs=true \
          -Dintrospection=true \
          -Dvapi=true \
          -Dexamples=true \
          "$pkgname-$pkgver" \
          build
    ninja -C build
}

# See: https://github.com/wmww/gtk4-layer-shell/issues/12
# check() {
# ninja -C build test
# }

package() {
    DESTDIR="$pkgdir" ninja -C build install
    install -D -m 644 "$pkgname-$pkgver/LICENSE" "${pkgdir}/usr/share/licenses/${pkgname}/LICENSE"
}

Then mixxc can be successfully built \o/

Sorry for the noise. Hopefully this issue helps someone.

Cheers!

No problems, gtk4-layer-shell unlike it's gtk3 predecessor is not yet packaged for all Linux distributions. (I had to make a template for Void Linux myself)

If you have any other questions, or if some things confuse you, feel free to open an issue, this might help me to improve README for everyone else.
