1. cmake设置C++标准 cmake有如下一些方式设置C++标准: 1.1 CMAKE_CXX_FLAGS 方式: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17") 1.2 CXX_STANDARD 方式: 设置单个目标的C++标准 add_executable(myapp main.cpp) set_property(TARGET myapp PROPERTY CXX_STANDARD 17) set_property(TARGET myapp...
[MSVC 踩坑记录]set(CMAKE_CXX_STANDARD)需要设置/Zc:__cplusplus 最近在使用 MSVC 编译项目 CFSApp 的时候,eigen 总是报错说我 C++ 语言标准太低,在 cmakelists 中写了set(CMAKE_CXX_STANDARD 17)也不行,后来发现是 MSVC 的问题。 在使用 MSVC 的时候,如果没有带上/Zc:__cplusplus选项, 宏__cplusplus...
通过设置变量 CMAKE_CXX_STANDARD 的值来设置项目的 C++ 语言标准。 set(CMAKE_CXX_STANDARD17)set(CMAKE_CXX_STANDARD_REQUIREDON) C++ language standard
set( my_std_pre "-std=" ) endif() set( basic_cxx17 "c++17" ) set( str_cxx17 "${my_std_pre}${basic_cxx17}" ) include( CheckCXXCompilerFlag ) check_cxx_compiler_flag( "${str_cxx17}" _cpp_17_flag_supported ) if ( _cpp_17_flag_supported ) set( CMAKE_CXX_STANDARD 17 )...
CMakeLists.txt 是用于编写 CMake 构建脚本的文件。下面需要重点讲述CMake语法,其语法主要由以下几个部分组成: 注释 使用井号(#)开头的行是注释行,会被 CMake 忽略。 # 这是一个注释 变量 在CMake 中,你可以使用set()命令定义变量: set(VARIABLE_NAMEvalue) ...
如何在不为每个特定编译器编写标志的情况下以 C++17 为目标?我当前的全局设置不起作用: # https://cmake.org/cmake/help/latest/prop_tgt/CXX_STANDARD.html set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS OFF) # expected behaviour #set(CMAKE_CXX_FLAGS ...
It can't be overridden with -DCMAKE_CXX_STANDARD=17. Goal: Builds with Trezor support should work without manual intervention with system dependencies installed. Option 1/n: Do not set CMAKE_CXX_STANDARD (allowing CMake to use the compiler's default [2], which matches what we need for ...
我正在使用VS 15.3,它支持集成的CMake 3.8.如何在不为每个特定编译器编写标志的情况下定位C++ 17?我当前的全局设置不起作用: # https://cmake.org/cmake/help/latest/prop_tgt/CXX_STANDARD.htmlset(CMAKE_CXX_STANDARD17)set(CMAKE_CXX_STANDARD_REQUIRED ON)set(CMAKE_CXX_EXTENSIONS OFF)# expected behav...
set (CMAKE_CXX_STANDARD 17) set (CMAKE_CXX_STANDARD_REQUIRED ON) but I get the sense that's not the Right Way to do it. What is the Right Way? Is it this?: target_compile_features(Foo PUBLIC cxx_std_20) where Foo is the name of my target (and same for every target?) If...
#增加-std=c++17 set(CMAKE_CXX_STANDARD 17) 1. 2. 3. 4. 5. 6. 2、在执行 cmake 命令的时候指定出这个宏的值 #增加-std=c++11 cmake CMakeLists.txt文件路径 -DCMAKE_CXX_STANDARD=11 #增加-std=c++14 cmake CMakeLists.txt文件路径 -DCMAKE_CXX_STANDARD=14 ...
