在centos上无法通过POSIX/Python下的cmake

[hxxyyangyong]

我在mac上所有的步骤都能成功，但是迁移到centos上就出现了错误

各种版本：
cmake 3.20.2
Python 3.9.18
clang 16.0.6

不论是我自己构建：
cd mmkv/POSIX mkdir build cd build cmake .. make

还是直接
python3 setup.py install

都是如下的报错
报错信息如下：

I currently don't have a CentOS env at hand, it will take some time.
I noticed that in your posted log, you are using GCC. What's the version of it?
And what is the version of your CentOS?

[lingol]

I just noticed that your code is not up to date. Line 20 of PBUtility.cpp in the master branch.
https://github.com/Tencent/MMKV/blob/master/Core/PBUtility.cpp#L20

PS: the master branch is known for some GCC & Linux compile failures. You can checkout the dev branch for testing.

我可以试试dev分支，
但我在mac上执行都是OK的，只是将执行环境迁移到了centOS而已，当然两边的基础环境工具版本是不一致的。

dev branch is ok, need run setup.py ,custom build Still failed
