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 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

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

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.
