Solved Error: ‚To_String‘ Is Not A Member Of ‚Std‘

ROS error: ‘to_string’ is not a member of ‘ std ’ chenxinyun921的博客 2349 ROS跑代码编译出现：error: ‘to_string’ is not a member of ‘ std ’ My project worked nice but after I have installed the new FCOLLADA (a library) and and get this error: error C2039: ’string‘ : is not a into a wstring member of ’std‘ Any idea? Gah. Trees blocking my sight of the woods. Sorry. Edit: But why does it tell my that VGbits is of non-class type and refuse compiling? I know it is of non-class type, I instatiated an object VGbits of the type bitset, did I not? I think I

c++ error: ‘XXX’ is not a member of ‘std’

error：“to_string“ is not a member of ‘std‘等问题CMake解决方案在工作中遇到各种需要编译的工作，遇到了很多坑，发现C++相关真的还挺麻烦和精密的。

Not .net anything. Not Visual Studio anything. In a C++11 program I intend to use Unicode and wstring and wchar_t. I am doing some bit parsing and bit manipulations for something and I want to have some results of that parsing in wstring or wchar_t. Thus, I want to put the 0’s and 1’s from some process into a wstring. 然后也遇到了几个问题 1、 error: ` cout ‚ was not declared in th is scope 需要加上using namespace std; 然后再加 std::cout << "hello world" << endl; 我觉得这个是 std 对象的方法 cout 2、 error: ' cout ' is not a member of ' std ' 需要加上#include 文章浏览阅读4.2k次。一、错误描述昨天在编译 paho.mqtt.cpp-1.0.1 时出错，提示 error: ‚to_string‘ is not a member of ’std‘ ，在网上看了一下，类似的错误还有：error: ‚to_string‘ is not a member of ’std’error: ‚thread‘ is not a member of ’std’二、原因分析因为to_string 和thread 是 C++11 才支持的，所以出现这种错误的原因可能是编译

Indeed answer is not a part of the std namspace, change std::answer to answer: double answer = = 0.5*(h*b); Although you probably meant area rather than answer. That code should be in a member function. Try to avoid variable names like h, But why does b. It is more meaningful to name the height and base. Good Luck !! 在解决C++编译工作中遇到的复杂问题时，关键在于确认gcc与C++编译器版本匹配。若gcc版本过低，需升级到5以上以支持vc14。在CMakeList.txt中设置CMAKE_CXX_STANDARD为14，并启用标准要求，同时添加-D_GLIBCXX_USE_C99=1的编译选项，确保正确编译包含to_string等函数的代码。

So it’s not exact same to original question. In my case, std::format is working perfectly in VS2022, but not std::format_string or std::wformat_string. I have tried all suggestions and solutions online but then finally find out it’s because C ライブラリヘッダー in the old version MSVC (14.34.31933) the format header implement the feature with a different error：“to_string“ is not a member of ‘std‘等问题CMake解决方案，代码先锋网，一个为软件开发程序员提供代码片段和技术文章聚合的网站。文章浏览阅读1.4k次，点赞4次，收藏3次。博客提及编辑器存在bug错误，并涉及相关解决内容，但具体信息较少。

Qt中 error: ‚to_string‘ is not a member of ’std’解决方法

In gcc14 some functions were moved from std library to separate libs. Adding the correct include files for the new location solved the issue for other projects. I am trying to use std::to_string(), but get error: ‚to_string‘ is not a member of ’std‘. From this answer, it seems to be a problem with not supporting C++11. However, using “verbose build” as advised in this answer, I see -std=gnu++11 which I believe means that I am using C++11. It looks like I can use std::ostringstream instead, but I’d really like to understand why it is that I ‚ is space‘ : is not a member of ‚ std ‚ 解决方法换：ctype #include using std:: endl; using std:: cout; #include using std:: string; #include intmain (

本文介绍了一种在使用海思ARM交叉编译器arm-hisiv300-linux-g++进行dronecode-sdk交叉编译时遇到的’to_string’错误，并给出了详细的解决方案。

However, per our instructors directions, we are not allowed to included the entire standard library, only specific functions (such as string, cout, etc.) If I include my code functions perfectly. FMAT.hでは、FMATクラスの定義を完了するために、std::stringの定義が必要です。FMAT.cppでは、 #include „FMAT.h“ の前に #include でこの定義を行っています。FMAT.cppのメインファイルでは、そのようなことはしていません。文字列を前方に宣言しようとする試みは、2つのレベルで間違っています

It give me an error saying that ’stoi‘ is not a member of std, though I am sure that it is, in C++11. I have also enabled the C++11 in the compiler flag. Googling this yielded some results saying that MinGW does not support stoi,to_string () 1 It’s not supported on MinGW because of limitations in the MinGW runtime that need changes from MinGW developers. Take a look at these: Bug 52015 – std::to_string does not work under MinGW Bug 59076 – std::to_string (int ) could not be found in GCC 4.8.2 If you can use Boost, a good alternative is boost::lexical_cast (been there

@snr: OP is not getting a linker error, but a compiler error, saying that the function was not declared. This is not caused by using the gcc command 类似的错误还有 error to_string versus the g++ command. [G++/C++]: std::to_string -> compiler error „not a member of std“ – 오류 외국 자료를 찾아보니, 아마 컴파일러의 표준 버전이 안맞아서 생기는 문제로 볼 수 있습니다.

The errors mentioned by @Ingener74 are still in the json-lib, thus I created a small patch-file for that. On android, it adds the function std::to_string (common workaround implementation, found on stackoverflow) and std::strtold (workaround

在进行C/C++开发时，使用VS2019编译遇到错误C2039，提示“string”不是“std”的成员。问题源于VS2019的语法检查更加严格，缺少必要的头文件。解决方案是正确引入C++的头文件。
