写在前面

在下面的位置中写入(先mkdir bits)

stdc++.h文件内容:

参考 gcc 源码 gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/include/precompiled/stdc%2B%2B.h;

对于 llvm-clang/xcode-clang 来说, 需要用下面的头文件:

因为 llvm 没有 glibc. 参考:macOS-stdc.h;

gcc with brew

注意版本号, 每次更新之后都要改:

/opt/homebrew/Cellar/gcc/12.2.0/include/c++/12/bits/

llvm with brew

/opt/homebrew/opt/llvm/include/c++/v1/bits/

xcode

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1

之前是这个路径, 后来更新到 14 之后就变了

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1

一个不错的办法就是

g++ aa.cpp -v

此时会显示链接库和头文件信息

#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /opt/homebrew/include
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1

 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks (framework directory)
End of search list.

xcode 的命令行工具

安装了 xcode 就不需要了

/Library/Developer/CommandLineTools/usr/include/bits
