telepathy-qt4 and the Nokia QT SDK
This is not so much a question as it is a way for me to provide documentation where there is none.
Requirement: Must be able to compile an application that uses libtelepathy-qt4 using the Nokia QT SDK on Linux. This will allow compilation for Linux and Maemo using qtcreator. Yes of course it can be done from within scratchbox with no changes. But can it be done from outside scratchbox? Tried the following: -> Hoped for dumb luck and just attempted to compile. Compilation on x86_64 Ubuntu worked once I installed libtelepathy-qt4-dev. Compilation for maemo5 failed because libtelepathy-qt4.so does not exist in NokiaQtSDK/Maemo/4.6.2/sysroots/fremantle-arm-sysroot-10.2010.19-1-slim/usr/lib -> Downloaded telepathy-qt4 source tarball from the telepathy website. -> First time attempting to configure through madde failed with an error stating that I should use --host if I wanted to cross-compile. -> After reading through config.sub, I figured that the proper host alias should be "armel-linux". Added that and appropriate flags to --prefix and --eprefix. -> Configure now fails claiming pkg-config not found. -> Created a shell script to set PKG_CONFIG to the correct path and for completeness, also set up QTCORE_CFLAGS='-lQtCore' ; export QTCORE_CFLAGS QTCORE_LIBS='-DQT_SHARED -I/usr/include/QtCore' ; export QTCORE_LIBS -> After doing all this, configure succeeded and I checked the config.log to ensure that all was well. It seemed like it was. -> At this point make failed. mad make failed. Eventually I gave up at this point - and decided to cheat. tl;dr: Copied the telepathy-qt4 headers and libraries from scratchbox into the Nokia SDK fremantle directories. Now my code that uses telepathy-qt4 compiles for maemo5 and the binary runs flawlessly on the n900. PS: In my pro file I had to add unix { INCLUDEPATH += /usr/include/telepathy-1.0 LIBS += -ltelepathy-qt4 } to get it to compile for Linux and for Maemo. **** Edit: These are the steps I took for my Win7 dev vm. 1. Copy Source: /scratchbox/users/$USERNAME/targets/FREMANTLE_ARMEL/usr/lib Destination: C:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-10.2010.19-1-slim\usr\lib\ File: libtelepathy-qt4.a 2. Copy Within directory: C:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-10.2010.19-1-slim\usr\lib\ libtelepathy-qt4.so.0 to libtelepathy-qt4.so 3. Copy Source: /scratchbox/users/$USERNAME/targets/FREMANTLE_ARMEL/usr/include Destination: C:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-10.2010.19-1-slim\usr\include Directory: TelepathyQt4 |

That's no cheating, it's the right thing to do. The way to extend NQS madde part is to copy files to sysroot. You could envision doing a program that fetched the packages from the repos and extacted the debs over the sysroot. |

But while I was doing the copying, I never thought of it that way. |
Re: telepathy-qt4 and the Nokia QT SDK
uvatbc,
It seems that you have had a good fight and end up winning the "battle" to setup telepathy-qt4+tpsession on nokia sdk. Would you be so kind to tell me how you did get the telepathy-qt4 headers? I don't think I can just download the latest version from git and I tried "apt-get sources libtelepathy-qt4-0" but got errors later trying to configure/compile it on scratchbox... In fact, any information that can help me get from 0 to compile my first qt application using telepathy qt4/tpsession on nokia sdk will be greatly appreciated! I would love for example to be able to generate your qgvdial from source. Thanks in advance |

On a different note, would anyone be interested in actually putting together some sort of automation for that? I haven't personally heard any rumblings from Nokia about them doing it, but it would be quite useful, even if it was something rough. |

Re: telepathy-qt4 and the Nokia QT SDK
I'm trying this too and I've gotten it to build and run fine on my device but the problem I'm having is that the editor in QT Creator doesn't seem to see the header files and it shows the classes \ includes as unknown and doesn't offer suggestions as I type.
It's not the biggest problem in the world but would be nice if someone knows a way to get it to add these to QT Creator |

Re: telepathy-qt4 and the Nokia QT SDK
I tried to include telepathy and it worked. Have you selected Maemo target instead of Desktop or Simulator?
