例如,确保你的PATH环境变量正确设置了编译器的路径,或者检查是否有其他依赖项或库需要更新。 通过以上步骤,你应该能够解决“configure: error: your compiler does not have the necessary c++17 support!”这一错误。如果问题仍然存在,你可能需要查看项目的文档或寻求更具体的帮助。
'language feature' 需要編譯器旗標 'compiler option' 語言功能需要特定的編譯程式選項來支援。 錯誤C2429:語言功能 'nested-namespace-definition' 需要編譯程式旗標 '/std:c++17',如果您嘗試定義複合命名空間,該命名空間包含一或多個範圍巢狀命名空間名稱,從 Visual Studio 2015 Update 5 開始。 (在 Visual Stu...
具有指定名稱的多個符號位於範圍內。 請參閱下列錯誤訊息,以瞭解針對模棱兩可符號找到的編譯程式位置與宣告。 若要修正此問題,您可以使用其命名空間來完整限定模棱兩可的符號,例如std::byte或::byte。 您也可以使用命名空間別名,為包含的命名空間提供方便的簡短名稱,以在原始程式碼中釐清符號時使用。 如果頭檔包含...
Recommendation: Always use an include guard as shown above to optimize build times and avoid weird build errors. If your compiler supports and optimized #pragma once as an include guard mechanism, you should use that because it is usually more performant and less error prone than using an expli...

By default, MSVC is compatible with the ANSI C89 and ISO C99 standards, but not strictly conforming. In most cases, portable C code compiles and runs as expected. The compiler provides optional support for the changes in ISO C11 and C17. To compile with C11 and C17 support, use the com...
However, when I run meson setup, it shows Compiler for C++ supports arguments -std=c++11: NO when the compiler does support c++11. Here is my meson.build file: project('tutorial', 'cpp') cxx = meson.get_compiler('cpp') cxx_standards = {} foreach std : ['98', '03', '11', ...
Errors in the 1990 ISO C standard were corrected in two Technical Corrigenda published in 1994 and 1996. GCC does not support the uncorrected version. Iso9899:1990 标准里面的错误,在随后的 1994和1996发布的两个技术勘误中被更正。GCC 不支持 未更正的标准(即,GCC 里面指定C90标准,指的是1996年技术勘...
