Apple’s Xcode development system is superb for developing applications, but sometimes you just want to write C or C++ code for research or school. Composing a serious chunk of code with vi is no longer acceptable,* so users in this frame of mind are now using Eclipse, a modern IDE, that’s also free. Here’s how to get gcc without installing Apple’s Xcode and then install Eclipse for C/C++ programming.
What’s the Motivation?
At work recently, my wife was chatting with a colleague who was taking his first C++ class. She taught him how to use Eclipse on a Mac, even though he resisted at first. However, later, he came back and commented that the other students were trying to manage ever increasingly complex projects with the vi editor. It was taking them four, six, or even 20 hours in some cases to complete their homework each week. He finished his, typically, in 30 minutes. That’s the power of an IDE with a modern debugger. That last item, the debugger, can’t be emphasized enough. Print statements in your code are oh, so yesteryear with a tool like this. Time is money, and efficiency reflects on you as a programmer.
So if you’re a scientist, researcher or engineer who wants to write some research code, not intended as a GUI app, in Java, C, C++ or Fortran, you need to dump vi as an editor* (or Emacs or Nedit or whatever) immediately and get with this kind of IDE. Things are moving far too fast nowadays not to make this important move. (Clearly, I’m speaking to an older crowd here.**)
To be perfectly clear, Apple’s Xcode is a fabulous development system for C, C++, Objective-C and even Fortran 77***. You can build native OS X and iOS apps. But many researchers and scientists aren’t interested in Xcode. They’ve come from a Linux or other UNIX platform, like IBM’s AIX, and they just want to carry on their research in Eclipse on a Mac. This how-to is primarily for them. But, as I mentioned above, students who are taking their first programming class and own a Mac will also find this discussion useful — indeed mandatory. Remember, this is an introduction to whet your appetite and get you launched, not a complete Eclipse tutorial.

Also, this how-to for the sake of simplicity focuses on C/C++, but Eclipse can handle a myriad of languages, including, but not limited to, Java and Fortran. Let’s start with C/C++.
Getting the gcc Compiler
As an aside, when you install Apple’s Xcode (free from the Mac App Store only in Lion), gcc is automatically installed in /usr/bin. But if you have a mind to work with just Eclipse and gcc, you’ll need a way to install gcc without, if it pleases you, installing Apple’s Xcode first. (For reference, here’s a how-to on installing Xcode and gcc.)
There are at least two places I know of where you can get a gcc installer package for OS X:
- The OS X High Performance Computing page at Sourceforge managed by Dr. Gaurav Khanna at the University of Mass.
If you find other sources, let us know.
Installing Eclipse
Here’s a handy reference on where to get Eclipse for the Mac. Version 3.7 (“Indigo”) installs nicely in Lion and seems to work okay, but our household hasn’t put it to a grueling acid test with OS X 10.7.1.
Eclipse Download for CC++, 64-bit
The download is a …tar.gz file, so move it where you want the Eclipse directory to be because when you double click it, the package will be unzipped and untared right there. After Eclipse is installed, you’ll see it as an app, just like any other, with this icon.
It’s easy to create an alias to eclipse.app, if you wish, and place it in your /Application directory. Because the Eclipse IDE itself is written in Java, if you’re running a clean copy of Lion, you’ll need to download the Java runtime before the Eclipse app will launch. Just double-click on Eclipse, and it’ll trigger the required Java runtime download. Nothing else to do. If you’re in Snow Leopard, the Java runtime is already there.
Java runtime download
This first thing you’ll see when you run Eclipse is that it asks for the location of your workspace. I typically create a directory in /Users/john called Programming where I do any code development. (Which is not much these days.)
Workspace Selection
After you select your workspace, you’ll be confronted with an Eclipse peculiarity. A welcome page will be launched that brings a real feeling of WTF to many users. Here it is.
On your Mac, choose Apple menu System Preferences, click Keyboard, then click Text. Do one of the following: Check spelling for one language: Click the Spelling pop-up menu, then choose the language. Check spelling for multiple languages: Click the Spelling pop-up menu, choose Set Up, select each language to check automatically, then click Done. Mar 30, 2019 I am unable to use spell check in Lightroom Classic 8.2 running on MacOS High Sierra. Is anyone else having this issue? Is there a fix of this? Discussion moved from Adobe Creative Cloud to Lightroom Classic CC — The desktop-focused app - Moderator. MacOS has a system-wide spell-check feature. Fortunately, for reader JGC, this feature can be adjusted by the user, especially when a problem like his occurs. Recently, the spell-check in Facebook. Spell check problems in sierra for mac. After checking your text for spelling and other wiring errors, the Grammarly spell checker extension for Mac or Safari will suggest the right synonyms. That way, you get the best options and multiple synonyms that looks closely related to the terms you typed. What the Grammarly spelling checker does is more than fixing your writing errors. Aug 23, 2019 1) Click Edit Spelling and Grammar Check Grammar with Spelling. 2) Then click Edit Spelling and Grammar Check Document Now. 3) You’ll see the first error highlighted and you can use the Command + Colon keyboard shortcut explained above to highlight the next error.
Welcome screen
The trick is to realize that the icon on the far right, circled in red above, takes you into the workbench. For that named workspace, this one time is the only time you’ll see that screen.
Once the IDE is launched, there are just a few details before you can build a project. Again, for simplicity, lets stay with C/C++. From the Eclipse File menu, select “New” and then C++ Project.
Eclipse - New Project
Experienced Eclipse users know the drill. Name the project, make sure you’ve identified the location of your compiler in the Toolchain, and so on. (It may be different than the default install by Apple’s Xcode. The screen shot below shows Apple’s install of gcc, marked as MacOSX GCC, because I’d previously installed Xcode on that Mac.)
Configuration
Newbies may want to select the Hello World project just to see how things get set up. Make sure you work your way through the setup with Next > at the bottom and don’t click the Finish button too soon. A more detailed examination of this set up and the ins-and-outs of Eclipse are beyond the scope of this getting started article. The goal here is simply an introduction for Mac users. And you’re not alone. There’s a huge body of knowledge on the Internet about Eclipse. Here’s a start.
If all went well, you’ll be in the Eclipse IDE with the Hello World program in the editor and a Make file already created. This environment is called the Eclipse workbench.
Eclipse Workbench w/ default “Hello World” code
It may take you some start-up time to learn Eclipse, but trust me, coding the old way will soon bog you down. The Xcode and Eclipse developers learn from each other, so if you ever decide to get into OS X or iOS development, having earned your wings in Eclipse will pay huge dividends later.

In this tutorial, I will show you how to compile from source and install the current stable version of GCC on your macOS computer. The instructions from this tutorial were tested on Catalina (macOS 10.15).
Clang, the default compiler for macOS, supports only C, C++, Objective-C and Objective-C++. If you are interested in a modern Fortran compiler, e.g. you will need gfortran that comes with GCC. Another reason to have the latest stable version of GCC on your macOS is that it provides you with an alternative C and C++ compiler. Testing your code with two different compilers is always a good idea.
Building GCC 10 from sources could take some time, in my case it took about two hours on a MacBook Air with a 16GB of RAM.
In order to compile GCC from sources you will need a working C++ compiler. In the remaining of this article I will assume that you have installed the Command Line Tools for Xcode. At the time of this writing Apple’s Command Line Tools maps the gcc and g++ to clang and clang++. If you don’t have the Command Line Tools installed, open a Terminal and write:
which will guide you through the installation process.
Let’s start by creating a working folder:
Next, we can download and extract the latest stable version of GCC:
GCC 10 depends on a couple of other libraries (GSL, GMP, MPFR and ISL) that can be downloaded with:
the above four prerequisites will be built during the GCC build.
We are ready to compile GCC now. Be prepared that this could take some time … Since I’m interested only in the C, C++ and Fortran compilers, this is the configure command I’ve used on my machine:
The above command instructs the configure app to add a prefix to all the resulting executable programs, so for example if you want to invoke GCC 10.1.0 you will write gcc-10.1, the gcc command will invoke Apple’s version of clang.
If you are interested in building more compilers available in the GCC collection modify the –enable-languages configure option.
And now, the final touches:
Grab a coffee, maybe a book, and wait … this should take approximately, depending on your computer configuration, an hour … or more … and about 4.15GB of your disk space for the build folder.
Install the compiled gcc in /usr/local/gcc-10.1.0:
Mac Os Gcc
Now, you can keep the new compiler completely isolated from your Apple’s gcc compiler and, when you need to use it, just modify your path by writing in Terminal:
If you want to avoid writing the above command each time you open a Terminal, save the above command in the file .zshrc from your Home folder, e.g:
You should be able to invoke any of the newly built compilers C, C++, Fortran …, invoking g++ is as simple as writing in your Terminal:
Remember to erase the working folder from your HOME if you want to recover some space:
Next, I’ll show you how to check if the compiler was properly installed by compiling and running a few examples. GCC 10 uses by default the C++14 standard and C11 for the C coders, you should be able to compile any valid C++14 code directly. In your favorite text editor, copy and save this test program (I’ll assume you will save the file in your Home directory):
Compiling and running the above lambda example:
Download Gcc For Mac Os X 10 13 Download
We could also compile a C++ code that uses threads:
Next, we present a simple C++ code that uses regular expressions to check if the input read from stdin is a floating point number:
If you are a Fortran programmer, you can use some of the Fortran 2008 features like doconcurrent with gfortran-10.1:
Osx Gcc
The above code can be compiled with (assuming you’ve saved it as tst_concurrent_do.f90):
If you are interested in learning more about the new C++11/C++14 syntax I would recommend reading The C++ Programming Language by Bjarne Stroustrup.
