Error when compiling iAlert on Ubuntu 10.04 LTS

[Per Frøysa]

As far as I can see, handleSubscriptionOptions and
handleSubscriptionOptionsResult are defined in qxmpp.cpp.
But my experience with cpp is dated.

I would really like to use my Linux NAS-box to serve my Logitec Alert
Camera as this server is up and running at all time. My windows
computer is never left running when I am away. I really look forward
to get this software running.

Here is what make stops at:

logitechcameras.cpp: In constructor
‘Logitech700eCamera::Logitech700eCamera(QHostAddress, QString,
QString)’:
logitechcameras.cpp:22: error: cannot allocate an object of abstract
type ‘QXmpp’
qxmpp.h:109: note: because the following virtual functions are pure
within ‘QXmpp’:
/usr/local/include/gloox/pubsubresulthandler.h:168: note: virtual

std::string&, const gloox::JID&, const gloox::JID&, const
std::string&, const gloox::DataForm*, const std::string&, const

gloox 1.0 is the version you want. I have just tried a fresh install on a kububtu 11.10 machine with no issues. I will download a 10.04 VM and test. Are you using the 32 or 64 bit distro?

[Per Frøysa]

Thanks for your attention!

gloox 1.0 is noted.

In my Oracle VM uname responds like this:
perf@ubcray:~$ uname -a
Linux ubcray 2.6.32-30-generic-pae #59-Ubuntu SMP Tue Mar 1 23:01:33
UTC 2011 i686 GNU/Linux
I believe this is a 32 bit system.
Gnome desktop.....

Ok, This is what I did.
First I installed a fresh copy of Ubuntu 10.04 LTS
I updated all packages to the latest version and rebooted.
Then, from the terminal I installed the necessary dependencies (minus gloox):
# sudo apt-get install git-core qt-sdk libupnp-dev gstreamer0.10-ffmpeg phonon-backend-gstreamer

lucid still uses gloox 0.9.9.5, uninstall if necessary
# sudo apt-get remove libgloox-dev

at this point you may want to check for (and remove) files at:
# sudo rm -r /usr/include/gloox
# sudo rm /usr/lib/libgloox*
# sudo rm -r /usr/local/include/gloox
# sudo rm /usr/local/lib/libgloox*

Install gloox manually:
# cd ~
# wget http://camaya.net/download/gloox-1.0.tar.bz2
# tar xvjf gloox-1.0.tar.bz2
# cd gloox-1.0.tar.bz2 && ./configure && make && sudo make install

Install iAlert from github:
# cd ~
# git clone git://github.com/szatmary/iAlert.git
# cd iAlert && qmake iAlert.pro && make

For some reason /usr/local/lib is not in the library search path so I had to run the application like this:
# LD_LIBRARY_PATH=/usr/local/lib ./iAlert

[Per Frøysa]

Yes! I followed your procedure and the compilation/linking was
successful!
I could start ./iAlert without any library path problems.
Then iAlert started to download recordings. I waited untill all clips
were downloaded before I start to learn the user interface of iAlert.

I have no playback in the iAlert playback window, it is black.
The downloaded video files are OK, I can watch the videos using the
Totem Movie Player.
Selecting a day in the calendar brings up the cliplist beneath it.
Clicking an entry in the cliplist causes just a text being written in
the console window where iAlert was started saying:
"156 Playing "path-to-file---.mp4" - but the playback window is still
black.

I cannot see live video. The text written to the terminal says:
152 Playing "rtsp://192.168.1.104/HighResolutionVideo"
iAlert(9209): couldn't create slave: "Unable to create io-slave:
klauncher said: Unknown protocol 'rtsp'.
"
My goal is to learn how to communicate with the camera for
transferring the events (clips) to my Excito B3 server running
Debian.
That server is head-less, no display. Then I would like to write a
dynamic web page to access the clips using an ordinary browser.
Hopefully, you will allow me to use your code to learn and as a
starting point.
At the age of 70 software writing is the best way of keeping my brain
alive...

Great, glad you got it working. If you are remoted in, or running in a VM, the video will not display (no hardware overlay support). But if you are on a physical box, then it is something with the phonon/gstreamer backend.

Feel free to use any code, Thats why I open sourced it.

I've been having trouble compiling this program, but followed the previous steps and it worked great (I ran into issues with my Qt 4.8.1 build, so I used an older library, which worked fine).  Thanks for your postings!
