基本构建步骤

• 下载ubuntu18.04_rootfs.tar.gz 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 编译参考教程 系统自带的cmake版本为3.10.2，编译vcpkg-2020.11时会报版本过低

  • 在板编译（qemu虚拟机我没搭建成功）

• 安装vcpkg, 正确设置VCPKG_ROOT环境变量。建议下载vcpkg-2020.11，我暂时用的是这个版本

  • Linux: vcpkg install libyuv
  • libvpx 提取码：xlnx (手动安装)
  • opus 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

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

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

root@pynq:~/cmake-3.14.5# ./bootstrap
