Install and configure Codeblocks for IGEP devices

Codeblocks is a free and open source, cross-platform IDE which supports multiple compilers including GCC and MSVC. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins. Currently, Codeblocks is oriented towards C and C++. It can also be used for creating ARM, AVR, D, DirectX, FLTK, Fortran, GLFW, GLUT, GTK+, Irrlicht, Lightfeather, MATLAB, OGRE, OpenGL, Qt, SDL, SFML, STL, SmartWin and wx programs and applications, although in some cases installing third-party SDKs or frameworks is necessary. More information here.

Codeblocks is not installed by default in IGEP SDK VM, because Eclipse IDE is full integrated with IGEP Firmware. If you don't like Eclipse IDE or you want to use Codeblocks anyway this How-to can be helpful to install, set up and use it.


There are some requisites to follow this guide:

Install Codeblocks in VM

sudo apt-get install codeblocks codeblocks-contrib 

Configure Codeblocks

Startup script

Codeblocks startup script ( will let you to load IGEP SDK YOCTO environtment variables to IDE. Don't execute this script if you want to compile with other environtments like x86.

cd Desktop/IGEP\ development/

Copy this code to

#! /bin/bash
source /opt/poky/1.2/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi 
exec codeblocks 

Give execute privileges to script:

chmod a+x ~/Desktop/IGEP\ development/

Add IGEP SDK Compiler and Debugger

Follow the next instructions to add IGEP SDK Yocto support:

Image 6: Add to Debugger intialization commands:

  • set sysroot /opt/poky/1.2/sysroots/armv7a-vfp-neon-poky-linux-gnueabi/
  • set auto-solib-add off

Using Codeblocks

You can create two types of projects on Codeblocks: custom Makefile or managed by Codeblocks. These examples can be used as a template for your project. The examples are:

  • C_example, Codeblocks-based “Hello World” program written in C.
  • Cairo_example, generates a png file named hello.png.
  • Cpp_example, Codeblocks-based “Hello World” program written in C++
  • Dbus_example, sends "Hello Wolrd!" using D-Bus message system.
  • Glib_example, simple “Hello World" written using Glib library.
  • Gstreamer_example, ogg audio player using Gstreamer.
  • Gtk_example, Hello World in GTK.
  • C_example_without_autotools, custom Makefile “Hello World” program written in C.

Add Codeblocks examples to Workspace

Download CodeBlocks_examples.tar.bz2 and folow the next instructions:

Build programs

NOTE: Use Debug build if you want to debug later

Compile with: Build->Rebuild (Ctrl+F11).

Run programs

Once you compiled the program pass it from VM to IGEP via SSH, launch a terminal and type:

scp "pathtobinary" root@"IGEP IP for example:":/home/root

Get a remote shell prompt and run your program:

ssh root@"IGEP IP for example:"
./"binary"  "optional:arguments"

Debug programs

NOTE: When you debug programs using CodeBlocks "Step into" and "Step out" are not supported, because dinamic libraries symbols are not loaded by gdb.

Once you compiled the program pass it from VM to IGEP via SSH, launch a terminal and type:

scp "pathtobinary" root@"IGEP IP for example:":/home/root

Get a remote shell prompt and run gdbserver:

ssh root@"IGEP IP for example:"
gdbserver "VM IP for example:":1000 "pathtobinary" "optional:armguments"

Now use the followings steps to debug program:

NOTE: You cant use igep-remote-x program with IGEP firmware (chapter 3.3 "Remote X")
