Hi3559A V100R001C02SPC030 SDK包osdrv编译时提示如下：编译器是有安装的当加上sudo又提示如下：请问这是什么原因？

操作系统和软件介绍操作系统为openEuler 20.03 (LTS-SP1)   可用如下命令查询：cat /etc/os-release uname -iCodeViz介绍CodeViz是《Understanding The Linux Virtual Memory Manager》的作者 Mel Gorman 写的一款分析C/C++源代码中函数调用关系的open source工具（类似的open source软件有 egypt、ncc）。其基本原理是给 GCC 打个补丁（如果你的gcc版本不符合它的要求还得先下载正确的gcc版本），让它在编译每个源文件时 dump 出其中函数的 call graph，然后用 Perl 脚本收集并整理调用关系，转交给Graphviz绘制图形（Graphviz属于后端，CodeViz属于前端）。Graphviz + CodeViz编译安装1. 安装 GraphViz调用图的生成依赖于 GraphViz，所以首先要安装 GraphViz。可以下载源码包编译、安装。可以直接yum安装：[root@1ocalhost ~]# yum install graphviz2. 安装 CodeViz下载CodeVize源码包： 很多源都失效了，还好下面这个还在 https://github.com/petersenna/codeviz 进入/root目录下载[root@1ocalhost ~]# cd /root/ [root@1ocalhost ~]# wget https://github.com/petersenna/codeviz/archive/refs/heads/master.zip --2021-08-24 00:12:07-- https://github.com/petersenna/codeviz/archive/refs/heads/master.zip Resolving github.com (github.com)... 52.74.223.119 Connecting to github.com (github.com)|52.74.223.119|:443... connected.
