Description json_fwd.hpp no longer works. When using it in a header there is an "incomplete class" error in the corresponding code file. I have already figured out why this happens: The basic_json template differs between json_fwd.hpp an...
The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting -DJSON_MultipleHeaders=ON.CMakeYou can also use the nlohmann_json::nlohmann_json interface target in CMake. This target populates the appropriate usage requirements for INTERFACE_INCLUDE_DIRECTORIES...
积分 json.hpp是此处single_include/nlohmann或发布的单个必需文件。需要添加 #包括 < nlohmann / json.hpp > //为了方便 使用json = nlohmann :: json; 到要处理JSON的文件,并设置必要的开关以启用C ++ 11(例如,-std=c++11对于GCC和Clang)。 可以进一步使用fileinclude/nlohmann/json_fwd.hpp进行前向声明。js...
json_fwd.hpp的安装(作为cmake安装步骤的一部分)可以通过设置来实现-DJSON_MultipleHeaders=ON。 CMake的 也可以nlohmann_json::nlohmann_json在CMake中使用接口目标。此目标填充适当的使用要求,INTERFACE_INCLUDE_DIRECTORIES以指向适当的包含目录和INTERFACE_COMPILE_FEATURES必要的C ++ 11标志。 外部 要从CMake项目中...
json.hpp 唯一需要的文件。 只需要添加 AI检测代码解析 #include <nlohmann/json.hpp> // for convenience using json = nlohmann::json; 1. 2. 3. 4. 到你想要处理json的文件中,并且设置支持C++即可。 您可以进一步使用文件include/nlohmann/json_fwd.hpp用于转发声明。json_fwd.hpp的安装(作为cmake安装步骤...

如果我们看一下源代码,我们可以看到json是在json_fwd.hpp中定义的。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 using json = basic_json<>; json是basic_json的别名,因此您需要在声明basic_json之前转发声明json。如果您在json_fwd.hpp中向上滚动一点,您将看到basic_json的大量向前声明。因此,如果您想...
