+## 依赖
+
+桌面版本界面使用[sciter](https://sciter.com/), 请自行下载。（sciter暂不支持armhf）
+
+[Linux](https://raw.githubusercontent.com/c-smile/sciter-sdk/master/bin.lnx/x64/libsciter-gtk.so)
+
+## 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。)
+- 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)
+  - [opus](https://pan.baidu.com/s/1fxQayZ7FGq-Z0bn_pjBVfQ) 提取码：xlnx (手动安装)
+
+- 运行 `cargo run`
+
+## 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
