С Compiler For Mac Eclipse

17-04-2021 by



The Compiler is usually used on command line. The Debugger is running as command line version idbc or the graphical version idb (using JRE). I strongly recommend to not integrate the IDB Debugger to Eclipse since the graphical Debugger idb is already a Eclipse-Framework based solution.

Installing G++ on a Mac

С Compiler For Mac Eclipse

Dev-C for Mac has not been released by Orwell so far, so you can't use it if you switch to Mac. However, there are many C/C compilers that can easily replace all functions of Dev-C for Mac. With the help of this list of alternatives, you can find similar software to. The Eclipse Foundation - home to a global community, the Eclipse IDE, Jakarta EE and over 375 open source projects, including runtimes, tools and frameworks. Your question title is asking about compilers, yet you were actually interested in IDE (Integrated Development Environment). I will just assume you actually meant IDE. If you are on Mac, Xcode is generally not a bad choice as it is able to handle.

This section is intended to get you quickly started with C++ programming on your Mac. We'll be installing GCC 4.8.1 and GDB through a tool called Homebrew. If you want an additional guide on all of the following steps (except for installing GCC), the one by Moncef Belyamani is quite helpful. When you follow it, ignore anything about installing Ruby; that is, stop after setting up git.

Homebrew

Homebrew 'installs the stuff that you need that Apple don't'. It's like Ubuntu's apt-get, where one can install packages easily from repositories. Instead of having to download, configure, and install something yourself, all you need to do is run one command, and Homebrew will take care of the rest for you.

Pre-requisites

Homebrew requires that you have either Xcode or the Xcode command line tools installed on your Mac. Xcode is a free integrated development environment similar to Eclipse designed by Apple and mainly intended for iOS development or targeting the clang compiler. In this class, we will focus on gcc.

Xcode is quite a big install, so if you do not want to install it, you can get away with just installing the Xcode command line tools. See a Stackoverflow discussion for instructions on how to install the command line tools regardless of whether you have Xcode installed.

Installing Homebrew

You need xcode command line tools to install Homebrew. It is very easy to install Homebrew. Open your terminal, and run the following command:

If this doesn't seem to do anything, try killing it (CTRL C) and running it again. Or checkout homebrew website.

GCC and GDB

Installing GCC

As mentioned before, installing packages with Homebrew is very easy. First, we will add the repository from which the GCC package is available, so that Homebrew knows where to find the package we want. The repository is at https://github.com/Homebrew/homebrew-versions.

We do this by using the brew-tap command. Keep your terminal open, and run the following command. (For more information on how brew-tap works, visit the Homebrew docs):

Next, we will actually install the GCC package. Run the following command:

It might take a while before the installation is complete. When done, run the following:

The result should look like this:

USC Wireless Warning

Mac Eclipse C++

Many people have had issues running the brew install commands while connected to USC Wireless. If you are having trouble, you can either try using a wired connection, a different wireless connection, or do the following:

  1. Download a homebrew cache
  2. Open Finder, press CMD (command) + SHIFT + G and type /Library/Caches/Homebrew

  3. Extract the contents of the .zip you downloaded inside of the folder you opened in the previous step. Do not extract any of the .tar.bz2 or .tar.gz inside of the .zip folder.This should look as follows:

  4. Run brew install gcc48 in the Terminal as instructed above.

Using G++

To compile with the newly installed G++ compiler, use g++-4.8.

(Advanced) Aliasing g++

If you prefer calling g++ directly, you can also create a bash alias, as follows:

Put these two lines at the end of the file ~/.bashrc, and run:source ~/.bashrc

For more information on bash alias, take a look at the GNU Docs.

Installing GDB

Here also we use Homebrew. The following instruction has been taken from GDB on OS X Mavericks and Xcode 5 guide. To install, run the following brew command.

Check if it's installed:

The result should be gdb version 7 or higher.

Codesigning gdb

gdb is not going to debug yet. You'll get an error message like 'please check gdb is codesigned'. You need to create a certificate and sign gdb. By doing so you're telling the operating system that gdb is authorized to attach to other processes for debugging purposes. The following instructions have been taken from this Code Signing guide.

  1. Open application 'Keychain Access' (/Applications/Utilities/Keychain Access.app)

  2. In Keychain Access, select the 'login' keychain in the 'Keychains' list in the upper left hand corner of the window.

  3. Open the menu item in /Keychain Access/Certificate Assistant/Create a Certificate...

  4. Choose a name ('lldb_codesign' in the example, but you can use anything you want), set 'Identity Type' to 'Self Signed Root', and set 'Certificate Type' to 'Code Signing'. Click 'Create'.

  5. Click continue, continue and done.

  6. Click on the “My Certificates” category on the left side and double click on the new “lldb_codesign” certificate.

  7. Open the context menu for 'Trust' (click the triangle) and change the following:When using this certificate: Always Trust

  8. Now close this window, and enter your login password to confirm this change.

  9. Option-drag (this meaning holding the option key down and dragging) the new 'lldb_codesign' certificate from the login keychain to the System keychain in the Keychains pane of the main Keychain Access window to make a copy of this certificate in the System keychain. You'll have to authorize a few more times, set it to be 'Always trusted' when asked.

  10. Switch to the 'System' keychain and drag a copy of the 'lldb_codesign' you just made onto the Desktop.

  11. Switch to Terminal and then run the following command (copy paste it!): sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer

  12. Then right click on the 'lldb_codesign' certificate in the 'System' keychain (not 'Login') and select 'delete' to delete it from the 'System' keychain.

  13. Then reboot your system/computer.

  14. Finally you can sign gdb:codesign -s lldb_codesign /usr/local/bin/gdb

  15. If this command doesn't work...then panic! Just kidding, be sure that you have gdb installed and that gdb is actually installed in /usr/local/bin. You may want to try 'which gdb' in your Terminal to figure out where it is.

  16. Finally, remove the lldb_codesign.cer file that's sitting on your desktop, and gdb should be working at this point. :)

Install a new version of Eclipse to use with C++

You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing MinGW and Eclipse. Or, just keep this document in your browser. You should read each step completely before performing the action that it describes.

Eclipse: Version 4.5 (Mars)

The Eclipse download requires about 200 MB of disk space; keep it on your machine, in case you need to re-install Eclipse. When installed, Eclipse requires an additional 200 MB of disk space.

Downloading

  1. Click Eclipse

    The top of the following page will appear in your browser.

    In this handout we will download Eclipse Standard 4.5 for Mac OS X 64 Bit; if your computer uses Mac OS X (Cocoa), continue below; otherwise look for the pull-down list showing Mac OS X (Cocoa) and instead choose either Windows or Linux and then continue below.

  2. Click the 64 Bit (under Mac OS X) under the heading Eclipse IDE for C/C++ Developers (the fourth selection from the top).

    You will see the following page (don't worry about the name of the institution underneath the orange DOWNLOAD button).

  3. Click the orange DOWNLOAD button. The site named here, in orange, underneath the DOWNLOAD button: United States - Indiana Unversity (http) is the random one chosen by the download page this time; yours may differ.

    This file should start downloading in your standard download folder. This file is about 200 Mb so it might take a while to download fully if you are on a slow internet connection (it took me about 5 minutes over a cable modem). Don't worry about the exact time as long as the download continues to make steady progress. In Chrome progress is shown on the bottom-left of the window, via the icon

    The file should appear as

    Terminate the window browsing the Eclipse download.

  4. Move this file to a more permanent location, so that you can install Eclipse (and reinstall it later, if necessary).
  5. Start the Installing instructions directly below.

Installing

  1. Double click the file eclipse-cpp-mars-R-macosx-cocoa-x86_64.tar.gz, the file that you just downloaded and moved. It will unzip the file and create an Eclipse application, which appears as

    Move this application into the Applications folder and put it on the dock for simple access. Now you are ready to perform a one-time only setup of Eclipse on your machine.

  2. Double-click the Eclipse icon on the Dock that you just created above.

    The following pop-up window will appear

    (note it says Eclipse Cpp here, because I already have Eclipse installed for my work with Python, so on my machine I renamed this application Eclipse Cpp.

  3. Click Open.

    The following splash screen will appear

    and then a Workspace Launcher pop-up window will appear.

    In the Workspace text box, your login name should appear between /users and /Documentsworkspace, instead of my name, richardepattis.

    Leave unchecked the Use this as the default and do not ask again box. Although you will use this same workspace for the entire quarter (checking projects in and out of it), it is best to see this Workspace Launcher pop-up window each time you start Eclipse, to remind you where your workspace is located.

  4. Click OK.

    Progress bars will appear at the bottom of the spash screen as Eclipse loads.

    Eventually the Eclipse workbench will appear with a Welcome tab covering it.

  5. Terminate (click X on) the Welcome tab.

    You will not see the Welcome tab when you start Eclipse after this first time. You should now see the following Eclipse workbench.

    Notice the C/C++ words/icon appear on the top left (in the Window title-bar) and below the upper right-hand corner (beneath the tool-bar).

Eclipse is now installed for C++.
