How to Install Code Blocks IDE on Ubuntu 16.04/Ubuntu 18.04, 19.04

Code Blocks is in the default Ubuntu package repository, so you can open up a terminal window and run the following command to install it.

sudo apt install codeblocks

However, Ubuntu repository only contains the outdated version (Code Blocks 16.01). To install the latest version, download the latest version.

wget http://sourceforge.net/projects/codeblocks/files/Binaries/17.12/Linux/Debian%20stable/codeblocks_17.12-1_amd64_stable.tar.xz

32 bit

wget http://sourceforge.net/projects/codeblocks/files/Binaries/17.12/Linux/Debian%20stable/codeblocks_17.12-1_i386_stable.tar.xz

Extract the tarball.

sudo tar xvf codeblocks_17.12-1_amd64_stable.tar.xz

sudo tar xvf codeblocks_17.12-1_i386_stable.tar.xz

Now in the current directory, there are many Code Blocks deb packages. We need to run the following command to install Code Blocks.
64 bit

sudo apt install ./codeblocks_17.12-1_amd64.deb ./codeblocks-common_17.12-1_all.deb ./libcodeblocks0_17.12-1_amd64.deb ./codeblocks-dev_17.12-1_amd64.deb ./codeblocks-headers_17.12-1_all.deb ./*wx*.deb

32 bit

sudo apt install ./codeblocks_17.12-1_i386.deb ./codeblocks-common_17.12-1_all.deb ./libcodeblocks0_17.12-1_i386.deb ./codeblocks-dev_17.12-1_i386.deb ./codeblocks-headers_17.12-1_all.deb ./*wx*.deb

Once installed, you can start Code Blocks IDE from Unity Dash or your preferred app launcher.

Choosing a C Compiler

Upon first launch of Code Blocks, you will be prompted with a Compilers auto-detection window:

Tow popular open-source C compilers available for Linux are:

• GNU C Compiler – the defacto-standard open-source C compiler
• Clang – Clang is much faster and uses far less memory than GCC and it provides extremely clear and concise diagnostics (error and warning messages).

To install gcc, run:

sudo apt install gcc

To install the Clang compiler:

sudo apt install clang

If you want to compile native Windows binaries on Linux, then you can install the mingw-w64 package.

sudo apt install mingw-w64

After choosing your default C compiler, you can start using Code Blocks to write programs.

You can also choose your default compiler by going to Settings > Compiler > Global Compiler Settings.

That’s it! I hope this tutorial helped you install Code Blocks on Ubuntu 16.04/Ubuntu 18.04, 19.04.
