initializer lists是c++11的特性 (参见std::initializer_list(点击打开链接)) so,对于cmake生成的项目,我们就需要在CMakeLists.txt中添加如下编译选项 add_definitions(“-std=c++11”) 或者 add_definitions(“-std=gnu++11) 然后重新生成makefile,编译警告就消失了。

1)在 CMake 中添加-std=c++11编译选项可以通过设置CMAKE_CXX_FLAGS变量来实现。在 CMakeLists.txt 文件中添加以下代码: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 1. 这会将-std=c++11添加到编译器的选项中。 2)仅针对特定的目标添加该选项,可以使用target_compile_options命令。例如: ...

After looking at this, I can't help but think the point is to trigger the CPP 11 std lib. But that makes no sense, so why is this part of the example?Contributor czoido commented Mar 4, 2022 Hi @LeeRuns, The add_definitions("-std=c++11") is there because the required library ...
