In June/July 2011 I had the misfortune to program for a Symbian/Nokia phone. Really bad experience. Below  a list of all the shit I had to go through to get QtCreator working somewhat.

• crappy error messages. ‘a data abort exception has occured’
• qml is a complete paradigm shift
• unstable operating system. ‘it might be in an unstable state if you interrupt the working of this program’
• version control unfriendly. Often a file added by somebody else must be readded in the repository which leads to duplicate entries in the project file.
• memory mapping of large files doesnt work
• memory requirements are too stringent
• debugger doesn’t work. One always gets memorydumps without access to the symbols.
• bloody slow compilation
• the X7 Symbian 3 phone is slow.
• Try to get the audiostream from a decoder. With phonon it should be possible but it doesnt work.
• just click on the ‘documentation’ tab left. You get an error ‘Die Seite konnte nicht gefunden werden ‘qthelp://com.nokia.qtcreator.220/qdoc//doc/index.html
• sometimes code gets hidden and cannot be unhidden unless the project is opened and closed.
• how can one create a subfolder ?
• copying files to and from the phone more often than not does not work.
• try to use phonon or qtmultimedia to access the decoded part of a video !
• searching in all project files simply doesn’t work.
• qt creator often seems to require compilation twice.  ‘build’ and then ‘run’, leads to a rebuild.
• no linux, nor vmware. You must program in windows
• QtCreator crashes when there are more than 4000 error messages from the compiler.
• sometimes when adding a new file, it insists to add it somewhere in a subdirectory.
• The arm processor in those phones is not fully functional. For instance the ‘smull’ and ‘adc’ instructions are not supported. Mainly because it is based on a too old model of the processor.
• ‘piss-poor’ headphone volume; something many buyers noted as well
• Filenames (without their paths) are used to identify files. So the same filename at twop different locations is treated by the make system as the same file.
• How to set the volume of th phone ?  Yes a truly horendous hack by obtaining the address of a undocumented function and then hoping that it will actually point to the right thing ! http://bugreports.qt.nokia.com/browse/QTMOBILITY-830
• No support from Nokia what_so_ever. Even if you are hired by them (which I inderectly was !)

I was so happy that I could stop programming for/on this utter swamp of a platform.
