This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

根据报错提示，你漏掉了 -std=c++11 flag，可能是改错了CMakeList.txt文件导致的

[741075810]

CMakeList.txt 文件我是这样改的 if (CMAKE_CXX_COMPILER_ID STREQUAL "Clang") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread --std=c++11 -O2") elseif(CMAKE_CXX_COMPILER_ID STREQUAL "MSVC") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DNOMINMAX -O2 /std:c++11 /arch:AVX /source-charset:utf-8") else() set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread --std=c++11 -O2 -march=native") endif()

是我哪里改错了吗

[kiranosora]

用的编译器是gcc吗？版本是多少？如果版本过低建议升级下gcc

[741075810]

是gcc，版本是10.1.0的，应该不会低了吧

[kiranosora]

清空build目录，重新运行一下cmake，看下CXX_FLAGS是什么

[Sberm]

试下这个:

export CC=`which gcc`
export CXX=`which g++`

请问您这个问题解决了吗？我也遇到了

[biyou]

加上这个解决了 set (CMAKE_CXX_STANDARD 11)
