你用的什么编译器？

报错信息显示缺少 libstdc++

你把执行 cmake -P package.cmake 的输出日志全部贴出来，我需要看看 cmake configure 过程的信息。

试试 sudo yum install libstdc++-static

[altairwei]

另外，你的执行 cmake 命令的 shell 的环境变量 PATH 包含了 libstdc++.so 所在位置吗？

看来就是　没有安装　static 的，　只是安装了　so 的

你试试：

git fetch
git checkout develop
cmake -P package.cmake

[hooklab]

你试试：

git fetch
git checkout develop
cmake -P package.cmake

牛逼，已经编译成功，运行起来了，怒赞！！ 有紧急修复？

忘了修复了啥，挺多内容的，可能是依赖问题。
