falco/userspace/engine/rule_reader.cpp:31:21: error: ‘class YAML::Node’ has no member named ‘Mark’

源码编译Falco时报错

已经执行了如下语句：

apt install libssl-dev libc-ares-dev libprotobuf-dev protobuf-compiler libjq-dev libgrpc++-dev protobuf-compiler-grpc libcurl4-openssl-dev libyaml-cpp-dev

还是报错，已经安装了libyaml-cpp-dev。没有效果，

https://falco.org/docs/getting-started/source/官网上有这么一句：

If you are on Ubuntu 18.04, instead of cmake .. do cmake -DUSE_BUNDLED_DEPS=ON ...

本人的系统刚好是Ubuntu 18.04.2 LTS \n \l

所以执行

 cmake -DUSE_BUNDLED_DEPS=ON .. 

即可。

它会下载源码进行编译安装：

-- Downloading...
   dst='/home/jack/code/falco/falco/build/yamlcpp-prefix/src/yaml-cpp-0.6.2.tar.gz'
   timeout='none'
   inactivity timeout='none'
-- Using src='https://github.com/jbeder/yaml-cpp/archive/yaml-cpp-0.6.2.tar.gz'
-- [download 100% complete]
 

后面还是会报错：

重新下载编译一次，就好了。

Ubuntu 20.04.4 LTS  也报错误：

解决方式同上。
