[c++] How do I install g++ on MacOS X?

I want to compile C++ code on MacOS X, using the g++ compiler. How do I install it?

This question is related to c++ macos g++

The answer is


Installing XCode requires:

  • Enrolling on the Apple website (not fun)
  • Downloading a 4.7G installer

To install g++ *WITHOUT* having to download the MASSIVE 4.7G xCode install, try this package:

https://github.com/kennethreitz/osx-gcc-installer

The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.

The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.


Download Xcode, which is free with an ADC online membership (also free):

http://developer.apple.com/technology/xcode.html


Type g++(or make) on terminal.

This will prompt for you to install the developer tools, if they are missing.

Also the size will be very less when compared to xcode


xcode is now available for free from the app store. Just "buy it" (for free) and it will download. To get the command line tools go into preferences/downloads and "install command line compiler tools".

Instead of gcc you are using clang, but it works the same.
