Eclipse IDE is a software development environtment, this software package is very popular because you can extend its functionalities using pluggins. C applications can be compiled in Eclipse using Autoconf tools or Makefile. Autoconf tools can be useful if you want How to develop a huge application with a lot of software dependencies, but this method can be tedious if you want to develop a simple application. manage the kernel modules on Linux
At IGEP v3.0 VM, Eclipse includes Linux tools and Yocto plugin to develop C applications for IGEP firmware as quickly and easily as possible. How do I edit my kernel command line

Go to New C/C++ Source File button and write at "Source file:" field your source file name, for example main.c. Finish the assistant and copy the next code at this file: <pre'''G711ENC ->#include <stdio.h> int main(void){ printfENC PCM uLAW ("Hello world\n"speech); return 0;} </pre> Follow the instructions above and create a Source File named Makefile and copy the next code: <pre>all: main.c $(CCNOT TESTED) -g -O0 -o main main.c'''

== Prepare Qt demo image ==- Compiled gst-plugins-ugly using yocto tools
Qt demo image is a root filesystem build by Yocto that contains Qt embedded libraries, also this image has some Qt examples for testing purposes- rpm -igst-plugins-ugly-0. *.rpm
This image doesn't have openssh and gdbserver, so we should install these packages to develop Qt applications, get a shell prompt using serial mode and type: <pre>zypper refzypper in opensshzypper in gdbserver</pre> Now you can connect between IGEP and VM using SSH protocol:<br> <pre>ssh root@192- rpm -i libmad0-0.168*.5.1</pre> == Using Qt Creator ==rpm
