把: MoonGen_submodule_update.tar.gz 发到内网 CentOS 7.4机器上.

二, 内网编译

环境说明:

MoonGen 对 编译器, 汇编器, 链接器 要求较高,
CentOS 7.4 默认 gcc 4.8.5 版本太低

环境参考:

分别升级GCC 与 ld

GCC 升级方法1

GCC 版本  我编译升级的是 7.5, 可参考以下链接

CentOS7 升级GCC 7.5

binutils  我编译升级的是 2.36

GCC 升级方法2

同时升级 GCC 与 ld
yum install devtoolset-9

scl enable devtoolset-9 bash
