出现“std::filesystem' has not been declared”错误通常意味着编译器没有正确识别或使用C++17标准,其中std::filesystem是C++17中新增的一个库。以下是一些解决这个问题的步骤: 确认编译器和C++标准: 确保你使用的编译器支持C++17或更高版本。例如,GCC 7及以上版本、Clang 5及以上版本、MSVC 2017及以上版本都...
查阅资料后知道,出现此类错误是由于GCC的C语言扩展与C标准产生了冲突。 寻找出错的原因:进入到工程目录下,在debug目录下Eclispe已经自动生成了Makefile,在终端上进入此目录,输入make命令,得到编译输出的更相信的信息,在第一个出错的信息中可以看到编译器给出了错误提示和解决方法:”and must be enabled with the -st...
