To check if GCC already exists by running the following command in your command promt gcc -v

• Install MSYS2 MSYS2.

• This will install the linux shell on your Machine.

• Note: Keep pressing ENTER to select the default installation instructions.

• This command will take a while to download and install all files.
• After this GCC is installed but you still need to add it to your path.

PATH

• To set the path to GCC Compiler

• Open Start and type environment variables

• Click Advanced System Settings

• In the System variables section add a new entry to PATH/ Path.

• Add the following two lines

• C:\msys64\mingw64\bin and C:\msys64\ming32\bin

• Note: The path may vary according to where you have installed MSYS2

• GCC installation is complete you may use gcc to compile programs If you still get this error gcc is not recognized as an internal or external command try this

Compiling

Locate your program
I will be giving this example considering .c program
cd into your desired directory where file is locate or type cmd in the adress bar
then type command
gcc -o name name.c
eg. gcc -o helloworld helloworld.c
The name after -o is the name given to exe file that is generated
Correct errors if any and run the above command again when done
If no errors are generated
Type name that is the name of your .exe
the program will have run

CODE::BLOCKS

You could also download CODE::BLOCKS IDE which comes with the GCC compiler
Download the binary release from here
Download the one that says mingw-setup.exe
Make sure that you dont have gcc previously installed in your computer
Follow the instructions
You will have to set the path manually as we did previously
The bin lies in C:\Program Files(x86)|CodeBlocks\MinGW\bin

MinGW
MSYS2
GCC

Thank you

C:\msys64\mingw64\bin and C:\msys64\ming32\bin

Typo: I think there should be C:\msys64\mingw32\bin

Thanks a lot!
