No developer account needed and you don't need to download the entire — and quite large Xcode package of executables. Within the Xcode Command Line toolkit, Mac users gain access to numerous useful tools, utilities, and compilers, including make, GCC, clang, perl, svn, git, size, strip, strings, libtool, cpp, and many others. Our website provides a free download of Clang GUI 1.1.7 for Mac. The most popular version among the program users is 1.1. The application relates to Developer Tools. Commonly, this program's installer has the following filenames: clanggui.zip and Clang GUI.zip etc.
All of the code in libc++ is dual licensed under the MIT license and the UIUC License (a BSD-like license).

Features and Goals
- Correctness as defined by the C++11 standard.
- Fast execution.
- Minimal memory use.
- Fast compile times.
- ABI compatibility with gcc's libstdc++ for some low-level features such as exception objects, rtti and memory allocation.
- Extensive unit tests.
Why a new C++ Standard Library for C++11?
After its initial introduction, many people have asked 'why start a new library instead of contributing to an existing library?' (like Apache's libstdcxx, GNU's libstdc++, STLport, etc). There are many contributing reasons, but some of the major ones are:
- From years of experience (including having implemented the standard library before), we've learned many things about implementing the standard containers which require ABI breakage and fundamental changes to how they are implemented. For example, it is generally accepted that building std::string using the 'short string optimization' instead of using Copy On Write (COW) is a superior approach for multicore machines (particularly in C++11, which has rvalue references). Breaking ABI compatibility with old versions of the library was determined to be critical to achieving the performance goals of libc++.
- Mainline libstdc++ has switched to GPL3, a license which the developers of libc++ cannot use. libstdc++ 4.2 (the last GPL2 version) could be independently extended to support C++11, but this would be a fork of the codebase (which is often seen as worse for a project than starting a new independent one). Another problem with libstdc++ is that it is tightly integrated with G++ development, tending to be tied fairly closely to the matching version of G++.
- STLport and the Apache libstdcxx library are two other popular candidates, but both lack C++11 support. Our experience (and the experience of libstdc++ developers) is that adding support for C++11 (in particular rvalue references and move-only types) requires changes to almost every class and function, essentially amounting to a rewrite. Faced with a rewrite, we decided to start from scratch and evaluate every design decision from first principles based on experience.Further, both projects are apparently abandoned: STLport 5.2.1 was released in Oct'08, and STDCXX 4.2.1 in May'08.
Platform Support
libc++ is known to work on the following platforms, using g++ and clang. Note that functionality provided by <atomic> is only functional with clang.
- Mac OS X i386
- Mac OS X x86_64
- FreeBSD 10+ i386
- FreeBSD 10+ x86_64
- FreeBSD 10+ ARM
- Linux i386
- Linux x86_64
Current Status
libc++ is a 100% complete C++11 implementation on Apple's OS X.
LLVM and Clang can self host in C++ and C++11 mode with libc++ on Linux.
libc++ is also a 100% complete C++14 implementation. A list of new features and changes for C++14 can be found here.
libc++'s C++17 implementation is not yet complete. A list of features and changes for C++17 can be found here.
A list of features and changes for the next C++ standard, known here as 'C++2a' (probably to be C++20) can be found here.
Implementation of the post-C++14 Technical Specifications is in progress. A list of features and the current status of these features can be found here.
As features get moved from the Technical Specifications into the main standard, we will (after a period for migration) remove them from the TS implementation. This process is detailed here.

Note
Please note that you do not need to install PlatformIO Core (CLI) separatelyif you are going to use PlatformIO IDE for Atom. PlatformIO Core (CLI) is built intoPlatformIO IDE and you will be able to use it within PlatformIO IDE Terminal.
Also, PlatformIO IDE allows one to install PlatformIO Core (CLI) Shell Commands(
pio
, platformio
) globally to your system viaMenu:PlatformIO>InstallShellCommands
.- Download and install GitHub’s official Atom text editor. PlatformIO IDE is built on top of it.
- Open Atom Package Manager
- Mac OS X,
Menu:Atom>Preferences>Install
- Windows,
Menu:File>Settings>Install

package - Install PlatformIO IDE.
PlatformIO IDE uses Clang for the Intelligent CodeCompletion. To check that
clang
is available in your system, pleaseopen Terminal and run clang--version
. If clang
is not installed,then install it and restart Atom:- Mac OS X: Install the latest Xcodealong with the latest Command Line Tools(they are installed automatically when you run
clang
in Terminal for thefirst time, or manually by runningxcode-select--install
- Windows: Download Clang 3.9.1 for Windows.Please select “Add LLVM to the system PATH” option on the installation step.WarningPLEASE DO NOT INSTALL CLANG 4.0. TEMPORARILY, WE SUPPORT ONLY CLANG 3.9.If you see a
FailedtofindMSBuildtoolsetsdirectory
error inthe installation console, please ignore it and press any key to closethis window. PlatformIO IDE uses only the Clang completion engine, whichshould work after that without any problems. - Linux: Using package managers:

PlatformIO IDE uses clang for the Intelligent Code Completion.To install it or check if it is already installed, please follow see the stepII. Clang for Intelligent Code Completion from Installation guide.
Warning
The libraries which are added/installed after the initializing process willnot be reflected in the code linter. You need
Menu:PlatformIO>RebuildC/C++ProjectIndex(Autocomplete,Linter)
.PlatformIO IDE uses PlatformIO’s pre-built GCC toolchains for Smart Code Linterand rapid professional development.The configuration data are located in
.gcc-flags.json
. This file will beautomatically created and preconfigured when you initialize project usingMenu:PlatformIO>InitializenewPlatformIOProjectorupdateexisting..
.Warning
If some libraries are not visible in PlatformIO IDE for Atom and Code Completion orCode Linting does not work properly, please perform
Menu:PlatformIO>RebuildC/C++ProjectIndex(Autocomplete,Linter)
Please navigate to PlatformIO Core Install Shell Commands.
Smart Code Linter is disabled by default for Arduino files(
*.ino
and .pde
) because they are not valid C/C++ basedsource files:- Missing includes such as
#include<Arduino.h>
- Function declarations are omitted.
There are two solutions:
Recommended! See Convert Arduino file to C++ manually.
To force Smart Code Linter to use Arduino files as C++ please
- Open
.gcc-flags.json
file from the Initialized/Imported project and add-xc++
flag at the beginning of the value ofgccDefaultCppFlags
field:
- Perform all steps from Convert Arduino file to C++ manually(without renaming to
.cpp
).
Warning
Please do not modify other flags here. They will be removed on a next“Project Rebuild C/C++ Index” stage.Please use build_flags for “platformio.ini” (Project Configuration File) instead.
