= How to develop with Qt under IGEP =Categorize new tutorials
== Overview ==How to manage the kernel modules on Linux
This guide can be helpful to learnt to develop Qt applications under IGEP Boards. Qt is a cross-platform application framework that is widely used for developing application software with a graphical user interface, and also used for developing non-GUI programs such as How do I edit my kernel command-line tools and consoles for servers. You can get more information [http://qt.nokia.com/ here].
There are some requisites to follow this guide===Included (IGEP GST DSP): ==='''AACHEDEC -> DEC AACHE (OK)'''
*[http://iseedownload.biz/component/zoo/item/igep-virtual-machine-sdk-yocto IGEP SDK VM]: follow the IGEP SDK SOFTWARE USER MANUAL (chapter 2.3 "Setting up and running the VM")<br> *IGEP Qt Demo: follow the IGEP SDK SOFTWARE USER MANUAL (chapter 6.1 "Create IGEP firmware bootable micro-sd card") and install qt4e-demo-image-igep00x0.tar.bz2 instead IGEP firmware. *[http://www.iseewavetlan.biz/products/processor-boards/igepv2-board IGEPv2], [http:/com/www.isee.bizSVV/productsMedia/expansion-boardsHTTP/productFAAC-igepHE-berlin IGEP BERLIN] or [http://wwwAAC.isee.biz/products/expansion-boards/product-igep-paris IGEP PARIS] *MicroSD Card (at least 2Gbytes)<br>aac
'''''"Link software "'''''gst-launch --gst-debug-level=2 filesrc location=sampleaache.m4a ! TIAuddec1 codecName=aachedec engineName=codecServer ! volume volume=0.25 ! alsasink sync=false
== Download and install Qt demo image to a SD<broutofthebox-> ==ok
Once you have open IGEP SDK VM, launch a terminal and type: <pre>cd Desktop/wget http://downloads.isee.biz/denzil/binary/qt4e-demo-image-igep00x0.tar.bz2 git clone git://git.isee.biz/pub/scm/igep-tools.gitcd igep-tools/scripts</pre> Insert a SD-Card media and use the igep-media-create script to copy the firmware to SD-Card media, required options are:
*'''MP3DEC --mmc </dev/sdX>> DEC MP3 (AUDIO ERRORS)'''
unformated MMC Card - Followed README file from ISEE - IGEP DSP - GST + DMAI Support Package 3.40.00
*--image <filename>http://www.stephaniequinn.com/Music/Canon.mp3
specify file used to create the bootable SD cardgst-launch --gst-debug-level=2 filesrc location=Canon. mp3 ! TIAuddec1 codecName=mp3dec engineName=codecServer ! volume volume=0.25 ! alsasink sync=false
*--machine <machine>'''Random fatal bit error'''
specify '''mp3-plugin doesn't resolve the machine. Options are igep0020, igep0030 or igep0032<br> error'''
For example, assuming the SD card device takes "/dev/sdf" and you have and IGEPv2 board (igep0020), type: <pre>./igep-media-create --mmc /dev/sdf --machine igep0020 --image /home/jdoe/Desktop/qt4e-demo-image-igep00x0.tar.bz2</pre> This should give you a bootable SD-card<br>
== Prepare Qt demo image =='''G711DEC -> DEC PCM uLAW (speech) (NOT TESTED)'''
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. '''G711ENC -> ENC PCM uLAW (speech) (NOT TESTED)'''
This image doesn't have openssh and gdbserver, so we should install these packages to develop Qt applications. Open a shell prompt using serial communication ===Not included (IGEP SDK SOFTWARE MANUAL chapter 3.1 "Using serial mode"GST DSP) and type the following commands: <pre>zypper refzypper in opensshzypper in gdbserver</pre> Now you can connect between IGEP and VM using SSH protocol:<br> <pre>ssh root@"IGEP IP for example: 192.168.5.1"</pre> == Using Qt Creator =='''ACCLCDEC -> DEC AACLE (NOT TESTED)'''

Network File System (NFS) The kernel command line syntax is a Distributed file system protocol originally developed by Sun Microsystems name=value1. These next parameters are supported in 1984, allowing a user on a client Computer to access files over a network in a manner similar to how local storage is accessedigep. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) systemini since IGEP-X_Loader 2. The Network File System is an open standard defined in RFCs, allowing anyone to implement the protocol4. More information [http0-2://en.wikipedia.org/wiki/Network_File_System here].<br>
In IGEP Boards, NFS protocol can be used to mount a whole root filesystem located in a remote disk, this method is useful to develop or test applications.<br> === [kernel] ===
