Unable to find the location of C++'s standard libraries in OS/X?

Question

I have looked at /System/Library, but I have not found the iostream library/module by

ack iostream

Where are the standard libraries in OS/X?

Answer 1

在 OS X 10.10 Yosemite 上，它们位于：

/usr/include/c++

Answer 2

Please make sure you have XCode installed first.

Without xcode you won't be able to develop C/C++ applications since xcode includes all linkable standard libraries and headers.

Answer 3

iostream是一个C ++的东西，而不是C.如果你适当地重新标记你的问题，你可能会得到更多的帮助。

Answer 4

for me it is under the Xcode library directory: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/.

My OS is Catalina.

Answer 5

Apple keeps moving it. To see the current location, run

xcrun --show-sdk-path

On Big Sur the location is:

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

Answer 6

IIRC, /usr/local/lib ... Try adding -L/usr/local/lib to your GCC build options. Although the stdc++ libraries should be in your linker path already. Compiler errors usually indicate missing headers / syntax error while linker errors indicate missing binary blobbage.

Answer 7

在 macOS MOJAVE 10.14 上，它位于：

usr/local/include/c++/

Answer 8

试试 /usr/lib/ 或 /usr/local/lib/
