按照如下步骤进行anakin的安装：
https://github.com/PaddlePaddle/Anakin/blob/developing/docs/Manual/INSTALL_ch.md

环境：
ubuntu18.04
make --version GNU Make 4.1
g++ --version g++ (Ubuntu 7.3.0-16ubuntu3) 7.3.0
cmake --version cmake version 3.10.2
protoc --version libprotoc 3.6.1

执行下面命令时：
$ sh Anakin/tools/x86_build.sh

出现以下error：

@duanlin0505 如邮件回复，请降低 GCC 版本。后续我们会完善高版本 GCC 的编译使用，谢谢！
