## 基本构建步骤
- 下载[ubuntu18.04_rootfs.tar.gz](https://pan.baidu.com/s/1pmjw7OBn5NbiCvM6GGaEgQ) 提取码：xlnx (我试了好几个版本的ubuntu系统，只有在这个上面成功了，编译好的可执行文件是可以在其他armhf系统下面用的。PS：如果你不放心系统来源，你也可以基于本教程在你的系统中编译，如果成功了记得提交方案来取代本教程。)
- [PYNQ官方资源](http://www.pynq.io)|[PYNQ-github](https://github.com/Xilinx/PYNQ)|[ubuntu](https://ubuntu.com/blog/microk8s-memory-optimisation)
- 下载编译[cmake-3.14.5](https://cmake.org/files/v3.14/cmake-3.14.5.tar.gz)  编译[参考教程](https://blog.csdn.net/weixin_43793181/article/details/118157012) 系统自带的cmake版本为3.10.2，编译[vcpkg-2020.11](https://github.com/microsoft/vcpkg/archive/refs/tags/2020.11.tar.gz)时会报版本过低
  - 在板编译（qemu虚拟机我没搭建成功）
  
- 安装[vcpkg](https://github.com/microsoft/vcpkg), 正确设置`VCPKG_ROOT`环境变量。建议下载[vcpkg-2020.11](https://github.com/microsoft/vcpkg/archive/refs/tags/2020.11.tar.gz)，我暂时用的是这个版本

  - Linux: vcpkg install libyuv 
  - [libvpx](https://pan.baidu.com/s/1fgi0PzOrT4VpL6p3MY-IVA) 提取码：xlnx (手动安装，至于为什么指定该文件，我想表达的是我基于该文件成功编译了，你也可以下载其他文件来代替本文件。)
  - [opus](https://pan.baidu.com/s/1fxQayZ7FGq-Z0bn_pjBVfQ) 提取码：xlnx (手动安装，原因同上。)

- 编译 `cargo build --release`

## 在 armhf 上编译

### 安装Ubuntu 18.04到SD卡

```sh
sudo tar zxmf ./ubuntu18.04_rootfs.tar.gz -C /your sd path/rootfs/
#用户名(usrname)：xilinx
#密码(passwd)：xilinx
```

### 安装cmake
```sh
tar -xzvf cmake-3.14.5.tar.gz
cd cmake-3.14.5/
#这两步可能需要很长时间，依次输入
./bootstrap
make -j4
sudo make install
```
```sh
root@pynq:~/cmake-3.14.5# ./bootstrap

### 安装依赖项

```sh
sudo apt install -y g++ gcc git curl wget nasm yasm libgtk-3-dev clang libxcb-randr0-dev libxdo-dev libxfixes-dev libxcb-shape0-dev libxcb-xfixes0-dev libasound2-dev libpulse-dev ninja-build
```

### 安装 vcpkg

```sh
tar zxmf vcpkg-2020.11.tar.gz
mv vcpkg-2020.11 vcpkg
vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=$HOME/vcpkg
export VCPKG_FORCE_SYSTEM_BINARIES=1
vcpkg/vcpkg install libyuv
```

```sh

### 构建

```sh
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
#git clone https://github.com/rustdesk/rustdesk
#目前只测试过rustdesk-1.1.8版本
#https://github.com/rustdesk/rustdesk/archive/refs/tags/1.1.8.zip
tar zxmf rustdesk-1.1.8.tar.gz
mv rustdesk-1.1.8 rustdesk
cd rustdesk
#需要修改rustdesk/Cargo.toml两个地方：
#第3行：version = "1.1.6"-> version = "1.1.8"
#第20行：whoami = "1.1" -> whoami = "1.2"

cargo build --release
#接下来漫长等待
#如果是下载阶段感觉不顺畅的，可以ctrl+c结束后重试，直到成功为止

### 测试
- 查看版本号
```sh
root@pynq:~/rustdesk# ./target/release/rustdesk --version

```
别高兴太早，启动服务只是获取了ID，你需要设置密码才能被其他终端访问。
- 设置密码
```sh
root@pynq:~/rustdesk# ./target/release/rustdesk --password qwertyuiop123123 #密码请随意，这只是个例子
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Connection refused (os error 111)', src/main.rs:106:55
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
#虽然有错误提示，但不影响设置密码
```
- 重启服务，等待连接
```sh
root@pynq:~/rustdesk# ./target/release/rustdesk --service &
[1] 20186
```
你可能会立刻打开PC版的rustdesk直接连接，不过连接之后你会发现
```sh
Unsupported display server type tty,x11 expected
```
如果你想要看到桌面，可能需要得到[sciter](https://sciter.com/)的支持，接下来我给出一种命令行连接的方式,这基于你在Windows PC或者Linux PC上安装了rustdesk。下面以Windows 7为例,测试目标机的SSH功能：
```sh
#找到你安装RustDesk的位置
C:\Users\Administrator\Desktop>cd C:\Program Files\RustDesk 
C:\Program Files\RustDesk>RustDesk.exe --port-forward ur_dev_id 11000 127.0.0.1 22
```
然后用SSH客户端去连接本地IP和端口
```sh
Connecting to 127.0.0.1:11000...
Connection established.
To escape to local shell, press 'Ctrl+Alt+]'.

连接的过程会弹出输入远程机密码，建议选上记住密码，这样下次你就可以直接在rustdesk APP上看到连接记录，并直接用APP上的TCP隧道功能连接而非命令行方式。当然，最好建议[@rustdesk](https://github.com/rustdesk)在APP界面上的[传输文件]()按钮左边再加一个[TCP隧道]()按钮，这样就不用命令行就可以连接目标设备了。
