How To Install GCC

How To Install GCCIn the past week I have been asked a countless number of times how to install GCC ( GNU Compiler Collection ). I have been using it in my C Video Tutorial.

I show you how to install GCC on Windows as well as on a Mac in the video below. Not only did I make a video, but I also have everything listed step-by-step below after the video. If you have any trouble setting this up, leave a comment below and I’ll try to help.

How to Install GCC on Windows

1. Download the MinGW Installer here ( Click the green download button )

2. Run the Installer

3. Pick which ever languages you want to compile as the installer runs. Make sure you save MinGW in C:\MinGW though to avoid a ton of problems

4. Open the Command Prompt ( It is in the Accessories Folder in Start )

5. Add MinGW to the Path either by:

a. Type set PATH=C:\MinGW\bin;%PATH%

b. Or, go to Control Panel – System Security – System – Advanced Settings. Then click Environment Variables and click on PATH and Edit. Then add this to the end and save ;C:\MinGW\bin

6. In the Command Prompt type gcc -v to see if it worked. ( You may have to restart the Command Prompt )

How to Install GCC on Mac

It is very easy to install GCC 4.8.1 on a Mac if you have Mac Ports installed. Here are the steps to set everything up:

1. Go to MacPorts and install it by downloading the DMG and installing it. Make sure you pick the right version based on your operating system version.

2. Open your Mac Terminal ( Applications – Utilities – Terminal )

3. Update MacPorts by typing this in the terminal sudo port selfupdate

4. Install GCC 4.8 by typing this in the terminal sudo port install gcc48 ( This can take a while to install )

5. Now change the default version of GCC by typing this in the terminal sudo port select –set gcc mp-gcc48

6. Now type this in the terminal hash gcc

7. Test if you are using the new version of GCC by typing this in the terminal gcc -v

If you see version 4.8 in what follows, congratulations you have the updated version of GCC and you are ready to start writing C11 programs.

    Hi Derek,

    I had a different gcc version installed many months ago. Could this be why I’m not getting the version 4.8 after following all of these steps on my Macbook Pro?

    Derek, installing on a mac. everything worked fine until I got to the terminal command:
    sudo port select -set gcc mp-gcc48

    I get the following error:
    Usage: port
    [-bcdfknopqRstuvy] [-D portdir] [-F cmdfile] action [privopts] [actionflags]
    [[portname|pseudo-portname|port-url] [@version] [+-variant]… [option=value]…]…

    “port help” or “man 1 port” for more information.

    Can you offer any help?

    Hey mate,

    appreciate video, very helpful.

    However, I am installing on windows and it seems to all have worked ..except the ending and checking.

    when I type gcc -v into command it shows its installed etc

    I can go through dir to where I saved the files…

    my problem is… you click on a “testing” doc? which I assume you made some lil code in notepad earlier and saved it there ..

    I made one called “motto.cpp” in notepad but when I try to do your last step of typing in “gcc motto.cpp” I get an error message.

    this was the code I saved…


    int main()

    std::cout <gcc Motto.cpp
    motto.cpp:5:14: warning: missing terminating ” character [enabled by default]
    std::cout << "Solidum petit in profundis!\n;

    motto.cpp:5:1 error: missing terminating " character
    std::cout << "Solidum petit in profundis!\n;

    motto.cpp: In function 'int main()':
    motto.cpp:6:1: error: expected primary-expression before 'return'
    return 0;

    motto.cpp:6:1: error: expected ';' before 'return'

    please help me if you can???? so confused whats going wrong?

    email me back ….

      Change std::cout << "Solidum petit in profundis!\n; to std::cout << "Solidum petit in profundis!\n"; The "expected primary-expression" error normally occurs if the return type is wrong. expected ';' before 'return' probably occurred because a semi-colon is missing I hope that helps
