截至2022 年 9 月, 不, GCC 12 还不支持 std::format。MSVC( 16.10 及更高版本)是唯一完全支持 std::format 的编译器。 Clang 14 (带有 libc++14)也几乎完全支持 std::format。由于std::format 基于fmt 库,您可以使用 fmt::format 直到std::format 到达GCC。{fmt} 库 GitHub 存储库请参阅此处的编译...
此选项意味着 -ftrapping-math。 此选项导致定义预处理器宏 __SUPPORT_SNAN__。 默认值为 -fno-signaling-nans。 此选项是实验性的,目前不保证禁用所有影响信号 NaN 行为的 GCC 优化。 -fsingle-precision-constant 将浮点常量视为单精度常量,而不是将其隐式转换为双精度常量。 以下选项控制可以提高性能的优化...

gnu++1y GNU dialect of -std=c++1y. Support is highly experimental, and will almost certainly change in incompatible ways in future releases. -fgnu89-inline The option -fgnu89-inline tells GCC to use the traditional GNU semantics for "inline" functions when in C99 mode. This option is ...
Internally,basic_format_stringusesstd::convertible_to. So, this issue is likely the same as:#11038 This appears to be (arguably) a gcc-13 header bug, as it's using a built-in without checking for support for that built-in, as the system headers do elsewhere. ...
