On Microsoft Windows, MAPI header files are required to be installed, we recommend installing Visual Studio Express for this purpose.
So what should we do?
I've posted a question on Forum Nokia here.

Qt Mobility Messaging API on Windows
Qt Mobility Messaging API on Windows supports the MAPI messaging standard. However, this isn't straightforward to set up, as the Qt Mobility documentation states:
So what should we do?

Qt Mobility Messaging API on Linux
Getting Qt Mobility Messaging API to work on Linux (my Ubuntu Karmic Koala 9.10 system) needs some tricks.
The easiest way of test your setup is by compiling the Qt Mobility example writemessage.
Using my initial installation of Qt Mobility I got this error:
The most important error message is "cannot find -lQtMessaging_tp" which means that Qt Mobility Messaging library has not been properly built.
Qt Mobility on Linux requires QMF.
The Qt Mobility Messaging API documentation points this out:
To install QMF, checkout the latest QMF from Gitorious:
Then build it:
Add the following to your $HOME/.profile script:
necessary):
Troubleshooting
If you get this error while building a Qt Mobility Messaging app:
It means you have built Qt Mobility Messaging module properly, but you haven't specified the library path to QMF. See above workaround to link QMF library.
If you get this error when running a Qt Mobility Messaging app:
It means you haven't set QMF_LIBDIR properly. If you have, you may need to restart your computer.
The easiest way of test your setup is by compiling the Qt Mobility example writemessage.
Using my initial installation of Qt Mobility I got this error:
Starting: /usr/bin/make -w
.......
/usr/bin/ld: cannot find -lQtMessaging_tp

The most important error message is "cannot find -lQtMessaging_tp" which means that Qt Mobility Messaging library has not been properly built.
Qt Mobility on Linux requires QMF.
The Qt Mobility Messaging API documentation points this out:
On Linux QMF is required to be installed and the QMF_INCLUDEDIR and QMF_LIBDIR environment variables set to the messagingframework/src/libraries/qtopiamail and build/messagingframework/image/lib directories respectively.
To install QMF, checkout the latest QMF from Gitorious:
git clone git://gitorious.org/qt-labs/messagingframework.git qt-messagingframeworkIf you don't have git or don't want to use it, you can also download QMF as tarball archive.
Then build it:
export PATH=/opt/qtsdk-2010.01/qt/bin:$PATH qmake "QMF_INSTALL_ROOT=$PWD/image" qmf.pro make make installNow you need to rebuild Qt Mobility with Messaging (QMF) support (change paths as necessary):
export PATH=/opt/qtsdk-2010.01/qt/bin:$PATH export QMF_INCLUDEDIR=/opt/qt-messagingframework/src/libraries/qtopiamail export QMF_LIBDIR=/opt/qt-messagingframework/image/lib ./configure make make installMake sure it says "Checking QMF ... OK" during configure.
Add the following to your $HOME/.profile script:
necessary):
# Qt Mobility export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/qt-mobility-src-1.0.0-tp2/install/lib:/opt/qt-messagingframework/image/lib export QMF_INCLUDEDIR=/opt/qt-messagingframework/src/libraries/qtopiamail export QMF_LIBDIR=/opt/qt-messagingframework/image/libOnce Qt Mobility Messaging + QMF is set, to use it add the following to your .pro project file:
CONFIG += mobility MOBILITY = messagingThe writemessage example additionally uses the following workaround to link QMF library:
symbian|win32 {
} else {
# Temporarily link against local qtopiamail lib (should be part of the platform)
LIBS += -L $$(QMF_LIBDIR) -lqtopiamail
}
Then you should be set.Troubleshooting
If you get this error while building a Qt Mobility Messaging app:
/usr/bin/ld: warning: libqtopiamail.so.1, needed by /opt/qt-mobility-src-1.0.0-tp2/install/lib/libQtMessaging_tp.so, not found (try using -rpath or -rpath-link)

If you get this error when running a Qt Mobility Messaging app:

Installing Qt SDK 4.6.1 with Qt Creator 1.3.1 on Ubuntu
Now that Qt 4.6.1 SDK and Qt Creator 1.3.1 has been released by Nokia, I need to update my previous tutorial on setting up Qt Mobility development.
To build Qt Mobility apps, continue to Installing Qt Mobility libraries.
- Download Qt SDK Development Environment.
- Install Qt SDK. Launch Terminal, go to the folder where you downloaded Qt SDK distribution, and run:
chmod +x qt-sdk-linux-x86-opensource-2010.01.bin ./qt-sdk-linux-x86-opensource-2010.01.bin
Apart from a C++ compiler, a number of development libraries need to be present to enable Qt Creator to build your Qt applications. On Debian and Ubuntu, use the following command in a terminal to make sure they are installed:So just do what it tells you to:
sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-devIf you're using QtOpenGL, you'll also need OpenGL development files. You can use the following command to find out which packages to install:
sudo apt-get install libgl-dev libglu-dev
sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev sudo apt-get install libgl-dev libglu-devMake sure you add Qt bin folder to your PATH environment. Edit $HOME/.profile and add:
export PATH=/opt/qtsdk-2010.01/qt/bin/:$PATHNow you can build and run Qt applications.
To build Qt Mobility apps, continue to Installing Qt Mobility libraries.

Qt Creator 1.3 Help/Documentation Not Working?
I installed Qt Creator IDE 1.3 / Qt 4.6 SDK and having a problem that the Qt Creator Help/Documentation is not working / not showing / blank.
I've found the culprit, and the reason is because:
The solution is simple:
Doing the above procedure returns my Qt Creator help content properly.
I've found the culprit, and the reason is because:
You have used QtCreator with some Qt version before, and now have installed the same Qt version in a different location: There's a bug that in this case the information where to get the help file is not updated.
The solution is simple:
Please try explicitly removing the entries in Tools -> Options -> Help, and either restart QtCreator, or add the qch-files from your Qt version explicitly.
Doing the above procedure returns my Qt Creator help content properly.

Installing Qt Mobility Libraries on Windows 7
UPDATE: This article is obsolete. Please refer to the latest article, Installing Qt Mobility Final Libraries on Windows 7.
By following this article, you should be ready to develop Qt Mobility applications on Windows.
Note: This is only for Qt for Windows installation. If you want to develop Qt applications for Symbian on Windows, click here.
On Windows: PATH should be extended to include: C:\%TARGET_DIR%\lib
On my setup this folder is: C:\qt-mobility-src-1.0.0-tp2\lib
PATH can be extended through Start -> Settings -> Control Panel -> System -> Advanced -> Environment variables. Under System variables, select "PATH", click "Edit..." and append your Qt Mobility lib folder.
Reboot your system to apply your changes to system environment variables.
You're now ready to develop Qt Mobility applications in Windows. :-)
I first tried to unpack Qt Mobility into My Documents, but I can't compile it:
After reading Forum Nokia thread: Qt Mobility problem, I tried to reboot my computer, but didn't help. There's also steps to install Qt Mobility for Symbian.
After further investigation leads me that configure determines its expected build system to be symbian-sbsv2 based on running qmake on config.tests\make\make.pro :
I harcoded BUILDSYSTEM=win32-mingw by patching configure.bat here:
and now configure seem to work...
P.S.: I could have just "given up" and install Symbian S60 SDK first. :-)
You have two choices:
Then repeat the build process as usual.
I noticed some errors early in the "configure" process:
hate hesitate to use Windows. Qt Mobility's include folder, which should contain the header files, is still empty. Time to install a Perl interpreter.
Get Strawberry Perl for Windows (~ 32 MB).
Strawberry Perl automatically adds itself to your PATH system variable, you can check this by running perl -v :

By following this article, you should be ready to develop Qt Mobility applications on Windows.
Note: This is only for Qt for Windows installation. If you want to develop Qt applications for Symbian on Windows, click here.
- Install Qt SDK 4.6 + Qt Creator 1.3 for Windows.
- Install Strawberry Perl for Windows (~ 32 MB). The reason why Perl is needed is covered in the later in this article.
- Download Qt Mobility library sources.
- Unpack Qt Mobility source distribution into a folder without spaces, e.g. C:\qtmobility
- Apply this patch to config.tests/make/make.pro. You can use patch tool, but you can edit the file manually (view the patch to see changes).
- Launch Qt Command Prompt
- Set the PATH to Strawberry Perl :
set PATH=%PATH%;C:\strawberry\perl\bin
- Go to your Qt Mobility folder and run configure:
cd \qtmobility configure
This will configure Qt Mobility build with default target directory: C:\QtMobility
- Build Qt Mobility:
mingw32-make mingw32-make install
- Add C:\qtmobility\lib folder to your PATH environment variable (more on this below).
- To add Qt Mobility documentation in Qt Creator: Go to Tools -> Options -> Help -> Add. Then browse C:\qtmobility/doc/qch/qtmobility.qch.
Setting Environment Variables
In order to use Qt Mobility some environment variables need to be extended to locate the libraries, which are placed in the lib directory of the install path.On Windows: PATH should be extended to include: C:\%TARGET_DIR%\lib
On my setup this folder is: C:\qt-mobility-src-1.0.0-tp2\lib
PATH can be extended through Start -> Settings -> Control Panel -> System -> Advanced -> Environment variables. Under System variables, select "PATH", click "Edit..." and append your Qt Mobility lib folder.
Reboot your system to apply your changes to system environment variables.
You're now ready to develop Qt Mobility applications in Windows. :-)
Problems I Encountered... So You Don' Have To
I first tried to unpack Qt Mobility into My Documents, but I can't compile it:

configure -debug
Then repeat the build process as usual.

"Generating Mobility Headers..." Access is denied. 'perl' is not recognized as an internal or external command, operable program or batch file. ...This is one reason why I
Get Strawberry Perl for Windows (~ 32 MB).
Strawberry Perl automatically adds itself to your PATH system variable, you can check this by running perl -v :
C:\strawberry>perl -v This is perl, v5.10.1 (*) built for MSWin32-x86-multi-thread Copyright 1987-2009, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit. Complete documentation for Perl, including FAQ lists, should be found on this system using "man perl" or "perldoc perl". If you have access to the Internet, point your browser at http://www.perl.org/, the Perl Home Page.Unfortunately, Qt Command Prompt sets its own PATH environment variable, overriding. Before running configure, do:
set PATH=%PATH%;C:\strawberry\perl\binNow you can configure and build Qt Mobility on Windows properly.
