Sticky post or web page describing vompclient raspberry development setup

[sirwio]

My SD card got boorked some days ago and I have had to write a new image to the card. Unfortunately my notes of the steps required to setup a working develop environment for the vompclient on the raspberry could not be found...

Wouldn't it be nice to have a sticky post on this forum or perhaps even better - a web page on the loggytronic site like http://www.loggytronic.com/vomp-pi.php

These are the steps I took while setting up my new develop environment. It may not be optimal and can likely be simplified - Some parts may be plain wrong. Suggestions and review especially by Marten and Chris are welcome.

Download the "Rasbian Wheezy" image available from http://www.raspberrypi.org/downloads
Write the image to the SD card following e.g. the instructions on http://elinux.org/RPi_Easy_SD_Card_Setup

Boot Rasbian. Remember, the login username is pi and the password is raspberry. When the initial setup loads, change the memory split to give the GPU 128MB. Change other options to suit. Now execute:

sudo su -
apt-get install libavformat53 libmagick++5 liblockdev1
wget "http://www.loggytronic.com/dl/libcec1_1.8.1-1_armhf.deb"
dpkg -i libcec1_1.8.1-1_armhf.deb


At this point the box is configured to execute a vompclient raspberry binary.

The libcec development package below does not currently exist in the dl area. It can be downloaded from the forum sections but I suggest adding it to the dl site to make the setup simplified.

wget "http://www.loggytronic.com/dl/libcec-dev_1.8.1-1_armhf.deb"
dpkg -i libcec-dev_1.8.1-1_armhf.deb


Next we need to install various development libraries. Please review if these are the correct development libraries. Especially libmagick++-dev brings in tons of dependencies. Perhaps there are a more lightweight version available.

apt-get install libavcodec-dev
apt-get install libavformat-dev
apt-get install libmagick++-dev


Install git so that its possible to fetch the vompclient source code:

Code Select Expand


apt-get install git-core


If we continue to build vompclient at this stage the build will choke with a:

g++ -g -O0 -Wall -Wshadow -DDEV -D_GNU_SOURCE -DVOMP_PLATTFORM_RASPBERRY   -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads  -I/usr/include/freetype2 -I/usr/include/ImageMagick  -D__STDC_CONSTANT_MACROS   -c -o osdopenvg.o osdopenvg.cc
In file included from /opt/vc/include/bcm_host.h:50:0,
                 from osdopenvg.cc:36:
/opt/vc/include/interface/vmcs_host/vcgencmd.h:33:52: fatal error: interface/vmc_host/linux/vchost_config.h: No such file or directory
compilation terminated.
make: *** [osdopenvg.o] Error 1

One workaround is to replace line 33 in the file /opt/vc/include/interface/vmcs_host/vcgencmd.h with

Code Select Expand

#include "interface/vmcs_host/linux/vchost_config.h"

A better workaround is likely to add -I/opt/vc/include/interface/vmcs_host/linux to the INCLUDES in the GNumakefile.

exit from the superuser session to fetch and build as user pi

Code Select Expand


exit


Fetch the sources and start the build

Code Select Expand


git clone http://git.vomp.tv/vompclient.git
cd vompclient
make


Congratulation. You should now have a vompclient executable that can be started as:

Code Select Expand


./vompclient

The libcec-dev package in the post above is not working (only 519 bytes). Get it from here:http://forum.loggytronic.com/index.php?topic=620.0

You can also download it from
