= Using Code::Blocks for editing GNU Radio modules =

Code::Blocks is a widely used Integrated Development Environment (IDE) to develop C++ applications. This tutorial is supposed to give a howto get started using Code::Blocks with GNU Radio.

It is assumed you are using gr-modtool as described here and Code::Blocks is installed on your machine.

Getting Started
After you created your project folder etc. with gr-modtools there are a few steps to do.


 * Run cmake-gui and add a new entry called CMAKE_CODEBLOCKS_EXECUTABLE

Its value is a string with the path to your codeblocks executable.
 * Finish this CMake preperations by generating the CMake files. (Click on Generate Button)
 * Open the Shell of your choice. Change directory to your project folder and create a new subdirectory.

Maybe something like build-cb
 * execute

The -G option together with &quot;CodeBlocks - Unix Makefiles&quot; specifies the CMake Generator.

Possible Generators are described here.
 * Now you can find a your-project.cbp file in the current directory.
 * Open it using Code::Blocks



Using Code::Blocks
In the previous section it is described howto generate a Code::Blocks project with CMake. In this section there are some basic hints how to use Code::Blocks and thus have a quick start. In order to run a flowgraph use the your shell or GRC. Nevertheless there are some advantages if you Code::Blocks.


 * You can compile/install your project and in case of an error the erroneous line will have automatic focus.
 * Switch between .cc and .h file by hitting F11.
 * There is a project explorer with all files.
 * You may configure and use source code formatting.
 * There is auto-completion available.
 * Code folding
 * Switch between methods by selecting them from a drop-down menu.
 * etc.
