How to Install C++ Code::Blocks in Macintosh

By Stephen R. Davis

The Macintosh version of Code::Blocks for C++ relies on the Xcode distribution from Apple for its compiler. The installation is done in three separate parts for this reason.

Installing Xcode

Xcode is a free development package offered by Apple that you will need. Follow these steps to install it first:

  1. Open the Safari browser and go to the Apple Developer site.

  2. Click on Download Xcode to get the most recent version.

    This will open the Xcode download dialog box shown in this figure


  3. Click on the Free icon to change it to Install App. Click on it again.

  4. Enter your system password (the one you log in with when your Mac boots up).

    The icon changes to Installing.

    The download and installation takes quite some time, as Xcode is a little over 2GB as of this writing.

Installing the Command Line Tools

As big as Xcode is, you would think that it has everything you need, but you would be wrong. You need one more package from Apple to make your joy complete and to get a working gcc compiler on your Macintosh. Follow these steps to install the Command Line Tools for Xcode:

  1. Open the Safari browser and go to Apple Developer download website.

    You may be asked to sign up for an Apple Developer ID. Go ahead and do so — it’s free.

  2. Search for Command Line Tools for Xcode. Select the application shown in the following figure. Click on the Download icon.

  3. Double-click on the mpkg package that downloads to install it.

  4. Accept all of the default values.

    The installation should finish with Installation Was Successful.


Installing Code::Blocks

Now, you can finish your installation by downloading the Code::Blocks editor:

  1. Open the Safari browser and go to Code::Blocks Downloads page.

  2. Click on Downloads→Binaries.

  3. Click on Mac OS X.

  4. Select either the BerliOS or mirror for the most recent version.

    At the time of this writing, CodeBlocks-13.12 was the most recent.

  5. Install the downloaded Zip file into the Applications folder.

    If you have never installed an application from a third-party site, you may need to execute these extra steps before you can do so:

    1. Click on System Preferences.

    2. Click on Security and Privacy.

    3. Click the padlock in the lower-left corner of the dialog box to allow changes.

    4. Click on Allow Applications Downloaded from: Anywhere, as shown in the following figure.

      Once you have completed the installation of Code::Blocks, you may choose to return to this dialog box and restore the settings to Mac App Store.


  6. Double-click on the Code::Blocks icon.

    The first time you do this, the Mac OS will ask, “Are you sure you want to open it?”

  7. Select Don’t Warn Me When Opening Applications on This Disk Image and click Open.

    Code::Blocks should start and find the gcc compiler installed with the Command Line Tools.

  8. Select the gcc compiler, as shown in the following figure. Click on Set as Default and then click on OK to continue starting Code::Blocks.

    Code::Blocks will open with a banner page followed by a menu across the top of the dialog box.

  9. Select Settings→Compiler, then click the Have g++ Follow the Coming C++0x ISO C++ Language Standard. Click on OK to close the dialog box.

    You are now ready to build your first C++ program.
