This brief tutorial explains how to compile and run C/C++ programs in GNU/Linux operating system. If you’re a student or a new Linux user coming from Microsoft platform, then you might be wondering how to run the C or C++ programs in a Linux distribution. Because, compiling and running code in Linux platforms is little bit different than Windows. Auto tune vocal editing software. Let us get started, shall we?

I'd like to learn. PlayOnLinux is a piece of software which allows you to easily install and use numerous games and apps designed to run with Microsoft® Windows®. Few games are compatible with GNU/Linux at the moment and it certainly is a factor preventing the migration to this system. PlayOnLinux brings a cost-free, accessible.

Setup Development Environment

As you may already know, we need to install the necessary tools and compilers to run the code, right? Yes! Refer the following guide to install all development tools in your Linux box.

The development tools includes all necessary applications, such as GNU GCC C/C++ compilers, make, debuggers, man pages and others which are needed to compile and build new software, packages etc.

Also, there is a script named ‘manji’ that helps you to setup a complete environment in Ubuntu-based systems.

After installing the necessary development tools, verify them using any one of the following commands:

These commands will display the installation path and version of gcc compiler.

Compile And Run C, C++ Programs In Linux

First, let us see how to compile and run a simple program written in C language.

Compile And Run C Programs

Write your code/program in your favorite CLI/GUI editor.

I am going to write my C program using nano editor.

Note: You need to use extension .c for C programs or .cpp for C++ programs.

Copy/paste the following code:

Press Ctrl+O and Ctrl+X to save and quit the file.

To compile the program, run:

Or,

If there are any syntax or semantic errors in your code/program, they will be displayed. You need to fix them first to proceed further. If there is no error then the compiler will successfully generate an executable file named ostechnix in the current working directory.

Finally, execute the program using command:

You will see an output like below:

To compile multiple source files (Eg. source1 and source2) into executable, run:

To allow warnings, debug symbols in the output:

To compile the source code into Assembler instructions:

To compile the source code without linking:

The above command will create a executable called source.o.

If your program contains math functions:

For more details, refer the man pages.

Compile And Run C++ Programs

Write your C++ program in any editor of your choice and save it with extension .cpp. Auto tune efx 3 vs auto tune pro.

Here is a simple C++ program.

To compile this C++ program in Linux, simply run:

If there were no errors, you can run this C++ program under Linux using command:

Sample output would be:

Alternatively, we can compile the above C++ program using “make” command like below.

Did you notice? I didn’t use .cpp extension in the above command to compile the program. It is not necessary to use the extension to compile C++ programs using make command.

And run it using command:

For more details, refer man pages.

Hope this helps.

I am a new Linux user and student who used to write C or C++ programs on MS-Windows. Now, I am using Ubuntu Linux. How can I compile a C or C++ program on Linux operating systems using bash Terminal application?
To compile a C or C++ program on any Linux distro such as Ubuntu, Red Hat, Fedora, Debian and other Linux distro you need to install:
[donotprint][/donotprint]

1. GNU C and C++ compiler collection
2. Development tools
3. Development libraries
4. IDE or text editor to write programs

Step #1: Install C/C++ compiler and related tools

If you are using Fedora, Red Hat, CentOS, or Scientific Linux, use the following yum command to install GNU c/c++ compiler:
# yum groupinstall 'Development Tools'
If you are using Debian or Ubuntu Linux, type the following apt-get command to install GNU c/c++ compiler:
$ sudo apt-get update
$ sudo apt-get install build-essential manpages-dev

Step #2: Verify installation

Type the following command to display the version number and location of the compiler on Linux:
$ whereis gcc
$ which gcc
$ gcc --version
Sample outputs:

How to Compile and Run C/C++ program on Linux

Create a file called demo.c using a text editor such as vi, emacs or joe:

How do I compile the program on Linux?

Use any one of the following syntax to compile the program called demo.c:

OR

OR

In this example, compile demo.c, enter:

OR

If there is no error in your code or C program then the compiler will successfully create an executable file called demo in the current directory, otherwise you need fix the code. To verify this, type:
$ ls -l demo*

How do I run or execute the program called demo on Linux?

Simply type the the program name:
$ ./demo
OR
$ /path/to/demo
Samples session:

Compiling and running a simple C++ program

Create a program called demo2.C as follows:

To compile this program, enter:

To run this program, type:

How do I generate symbolic information for gdb and warning messages?

The syntax is as follows C compiler:
cc -g -Wall input.c -o executable
The syntax is as follows C++ compiler:
g++ -g -Wall input.C -o executable

How do I generate optimized code on a Linux machine?

The syntax is as follows C compiler:
cc -O input.c -o executable
The syntax is as follows C++ compiler:
g++ -O -Wall input.C -o executable

How do I compile a C program that uses math functions?

The syntax is as follows when need pass the -lm option with gcc to link with the math libraries:
cc myth1.c -o executable -lm

How do I compile a C++ program that uses Xlib graphics functions?

The syntax is as follows when need pass the -lX11 option with gcc to link with the Xlib libraries:
g++ fireworks.C -o executable -lX11

Can Dev-c Run On Linux Download

How do I compile a program with multiple source files?

The syntax is as follows if the source code is in several files (such as light.c, sky.c, fireworks.c):
cc light.c sky.c fireworks.c -o executable
C++ syntax is as follows if the source code is in several files:
g++ ac.C bc.C file3.C -o my-program-name
See gcc(1) Linux and Unix man page for more information.
