要使其成为独立环境的符合标准的独立实现,请使用选项-ffreestanding.然后它将定义__STDC_HOSTED__到 0,而不是对标准库中函数名称的含义进行假设。 fno-rtti选项: 禁用运行时类型信息 fno-exceptions选项: 禁用异常机制 总结:一般只有对程序运行效率及资源占用比较看重的场合才会使用, 如果要做这两个的话最好连libst...

libCrunG3.so Library When compiling code in GNU mode, the Oracle Developer Studio C++ compiler uses the GNU C++ library, but it also needs to link an additional library called libCrunG3.so to supply support functions for RTTI, exceptions, and other language features. This library corresponds ...

在编写程序时,GCC 提供了一个开关,允许程序员禁用 "逗号的左手操作数无效" 警告。"逗号的左手操作数无效" 警告主要是因为程序员使用逗号时,误将逗号用作操作数的一部分。禁用此警告有助于提高代码的可读性和易维护性。 为了帮助您禁用 "逗号的左手操作数无效" 警告,以下是一个示例: 代码语言:gcc ...
