编译安装的过程中遇到这个问题，请问各位大大怎么解决的？GCC更新到了5.30，ＣＭＡＫＥ版本也是最新。
CMake Error at storage/tokudb/PerconaFT/cmake_modules/TokuSetupCompiler.cmake:180 (message):
/usr/bin/c++ doesn't support -std=c++11 or -std=c++0x, you need one that
does.

有可能你/usr/bin/c++ 不是你更新到5.30的gcc，你可以用 /usr/bin/c++ -v 检查一下版本。
运行cmake时可以添加参数-DWITHOUT_TOKUDB=1，禁止安装tokudb引擎。
