Dev C++ Ubuntu Install
Most Linux system administrators and engineers are required to know some basic programming to help them in their daily tasks. If they want to go one step further into the development area as well (either as kernel or application programmers), then C or C++ is the best place to start.

In this article we will explain how to install C and C++ compilers and it’s Development Tools (build-essential) related packages such as make, libc-dev, dpkg-dev, etc. in Debian and derivatives such as Ubuntu and Linux Mint.
The build-essential software contains an informational list of software’s which are treated as important for building Debian packages including gcc compiler, make and other needed tools.
What is a Compiler?
Simply put, a compiler is a software program that processes instructions written in a programming language and creates a binary file that the machine’s CPU can understand and execute.
In Debian-based distributions, the most well-known C and C++ compilers are gcc and g++, respectively. Both programs were developed and are still maintained by the Free Software Foundation through the GNU project.
Installing C, C++ Compiler and Development Tools (build-essential)
Installing Boost on Ubuntu with an example of using boost::array: Install libboost-all-dev and aptitude: sudo apt install libboost-all-dev sudo apt install aptitude aptitude search boost Then paste this into a C file called main.cpp.
- Oct 31, 2019 Perform the steps below to install the GCC Compiler Ubuntu 18.04: Start by updating the packages list: sudo apt update. Install the build-essential package by typing: sudo apt install build-essential The command installs. To validate that the GCC compiler is successfully installed, use the gcc.
- Codeblocks and codelite are available on the software centre of ubuntu and Dev can be installed by installing Wine first from the software centre and then you can use the.exe setup which is used in windows. These are my personal favourites. There are many more.
If your system don’t have build-essential package installed in your system by default, you can install the latest available version from the default distribution repositories as follows:
Now we’re ready to start typing C or C++ code… or almost. We’re about to show you yet another tool to boost your development toolset.
Speeding Up C and C++ Compilations
When you know you’ll need to compile a program, make changes, then recompile again it’s great to have a tool like ccache, which as you will probably guess based on its name, is a compiler cache.
It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. Besides C and C++, it also supports Objective-C and Objective-C++. The only limitations are:
- Only supports caching the compilation of a single C/C++/Objective-C/Objective-C++ file. For other types of compilations (multi-file compilation, linking, to name a few examples), the process will end up running the real compiler.
- Some compiler flags may not supported. If such a flag is detected, ccache will silently fall back to running the real compiler.
Let’s install this tool:

In the next section we will see some examples of C and C++ code compilation with and without ccache.
Testing C and C++ with a sample Program
Let’s use the classical example of a very basic C program that adds two numbers. Open your favorite text editor and enter the following code, then save as sum.c:
To compile the above code into an executable named sum in the current working directory use the -o switch with gcc:
If you want to take advantage of ccache, just prepend the above command with ccache, as follows:
Then run the binary:

If you vocode a normal voice that has some white noise that as a result of the effects provided, the result will be a robotic kind of voice for the special effects.You can use other carrier waves for voices that are subtly different, for instance a musical tone, a sawtooth tone, or a synthesized string chord. Well, it synthesizes a modulator, which is usually a voice, in the left channel of a stereo track with the synthesized sound on the right in order to produce a modified version of the sound in the left channel. In case you do not see the vocoder effect in your Audacity software program, you will need to upgrade the software to the latest version.
While this basic example does not allow us to see the full power of ccache, for larger programs you’ll quickly realize what a great tool it is. The same applies for C++ programs as well.
