* fix: prevent initial clipboard sync from overwriting newer updates

* fix: invalidate initial clipboard snapshots on remote and file updates

* fix: handle clipboard changes during initial sync

Track clipboard changes even when they produce no sync message.
Refresh invalidated snapshots to preserve sync after Wayland startup.
Prevent repeated PeerInfo responses from restarting initial sync.

* fix: skip file clipboard reads when file sync is not required

Check is_file_required() before reading clipboard file URLs to avoid
unnecessary clipboard access when no session needs file synchronization.

* fix: refresh clipboard requirements before listener startup

Update Flutter's text and file clipboard requirements before starting the
shared clipboard loop so startup notifications use the current settings.

* fix: exclude disconnected sessions from clipboard requirements

Only count connected Flutter sessions when checking clipboard requirements.
Recompute them on disconnect so a remaining session with sync disabled
does not keep unnecessary clipboard reads enabled.

* fix: filter disconnected sessions from clipboard requirements

Exclude disconnected Flutter sessions from text and file clipboard
requirement calculations, even when their tabs remain open.

* fix: skip Wayland host startup clipboard broadcasts

Signed-off-by: fufesou <linlong1266@gmail.com>

* fix: respect initial clipboard sync setting on Wayland

Stop broadcasting startup selections through the normal clipboard sync
path. Keep generation invalidation for snapshots captured before the
listener becomes active.

* fix: wait for clipboard listener readiness before initial sync

Wait for Linux clipboard backends to finish subscribing before the
initial read. Update clipboard-master to use its readiness callback.

Report completion for empty or failed reads so initial sync does not
remain pending. Document snapshot invalidation across listener restarts.

* fix: wait for Linux clipboard readiness asynchronously

Use watch notifications to keep the connection loop responsive during
clipboard startup. Cancel readiness waits when the session channel closes.

Advance generation on readiness and capture it with each initial read
so listener restarts invalidate older snapshots.

* fix: preserve Wayland startup file clipboard sync

Distinguish startup selections from normal clipboard changes.
Process startup files through the existing client clipboard worker,
while keeping text initial sync and host startup suppression unchanged.

Signed-off-by: fufesou <linlong1266@gmail.com>

* fix: bound clipboard readiness waits on Linux

Add a five-second timeout to the initial-sync readiness wait and
log failures.

Update clipboard-master to support timeout and cancellation while
waiting for the initial Wayland selection.

Dependencies

Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.

Please download Sciter dynamic library yourself.

Raw Steps to build

  • Prepare your Rust development env and C++ build env

  • Install vcpkg, and set VCPKG_ROOT env variable correctly

    • Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
    • Linux/macOS: vcpkg install libvpx libyuv opus aom
  • run cargo run

Install vcpkg

git clone https://github.com/microsoft/vcpkg
cd vcpkg
git checkout 2023.04.15
cd ..
vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=$HOME/vcpkg
vcpkg/vcpkg install libvpx libyuv opus aom

Fix libvpx (For Fedora)

cd vcpkg/buildtrees/libvpx/src
cd *
./configure
sed -i 's/CFLAGS+=-I/CFLAGS+=-fPIC -I/g' Makefile
sed -i 's/CXXFLAGS+=-I/CXXFLAGS+=-fPIC -I/g' Makefile
make
cp libvpx.a $HOME/vcpkg/installed/x64-linux/lib/
cd

Build

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
git clone --recurse-submodules https://github.com/rustdesk/rustdesk
cd rustdesk
mkdir -p target/debug
wget https://raw.githubusercontent.com/c-smile/sciter-sdk/master/bin.lnx/x64/libsciter-gtk.so
mv libsciter-gtk.so target/debug
VCPKG_ROOT=$HOME/vcpkg cargo run

How to build with Docker

Begin by cloning the repository and building the Docker container:

git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .

Then, each time you need to build the application, run the following command:

docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder

Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:

target/debug/rustdesk

Or, if you're running a release executable:

target/release/rustdesk

Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
