In addition to those C23 features, there are new command-line options -std=c23, -std=gnu23 and -Wc11-c23-compat. These are equivalent to the previous options -std=c2x, -std=gnu2x and -Wc11-c2x-compat, which are deprecated but remain supported. ...

C23 removes unprototyped functions. It should be possible to reproduce these with older GCC (and Clang) with -std=gnu23 or -std=c23 set manually.gentoo-bot pushed a commit to gentoo/gentoo that referenced this issue Nov 17, 2024 sys-libs/gpm: build with -std=gnu17 … 0208a52 gentoo...

在windows下进行rust开发,编译器有两个选择要么是msvc,要么是MinGW。 msvc不多说,微软自家的C++编译器。 MinGW,是Minimalist GNU for Windows的缩写。它是一个可自由使用和自由发布的Windows特定头文件和使用GNU工具集导入库的集合,允许你在GNU/Linux和Windows平台生成本地的Windows程序而不需要第三方C运行时(C Runti...
