  Won't be able to help much without more information... Could you provide a bit more information ? (compilation log)

  the message you're pointing looks like at some point, it tries to link with QtCore and can't find it, most probably because of a path issue (-L) or because it was not created

  Might be worth taking this into account as well:

  And raising as recommended by warning your limit to 500 (like in CXXFLAGS)

  This looks like a bug in qmake. It is used to build the Makefile for the project (you can find the -L option in the Makefile produced).

  Looking at the qmake binary with:

  % strings /usr/bin/qmake | grep qt-everywhere

  produces lots of strings that begin with:

  /tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0

  If you want you could hand-edit the Makefile to remove this option from the link command. Alternatively:

  % sudo mkdir -p /tmp/qt-stuff-6474/source/qt-everywhere-opensource-src-4.7.0/lib

  will create the directory and silence the warning.

  Looks like you are building with MinGW GCC, but trying to link with Microsoft Visual C++ libraries. The two compilers are not compatible and libraries built with one cannot be mixed with the other.

  Well...

  It's sad, but I went back to the stable SDK (4.7.0), and everything is fine...

  Thank you for your help Scylla, even if I prefer the new SDK (better organisation)

  Builds with 4.7.2 fail if 4.7.1 has been uninstalled

  OK, here is the explanation. Hope it helps others with the same workflow.

  In 4.7.1, the include folder is at,
  QtSDK/include
  but now in 4.7.2 everything has been moved about, and it is at
  QtSDK/Desktop/Qt/4.7.2/msvc2008/include

  So you need to update your $QTDIR, and update your path to the bin folder which is at the new location in the new QTDIR.

  Also, you will need to update QT Settings in your vs2008 project.
  In Qt/QtOptions/Qt Versions, add the new version and path.
  Then, in Qt/Qt Project Settings/Properties, apply the new version from the dropdown list.

  See the general hints on "Deploying Qt Applications":http://doc.qt.nokia.com/stable/deployment.html and the specific instructions for "Windows":http://doc.qt.nokia.com/stable/deployment-windows.html

  These docs are available in Qt Assistant too.

  Hey,

  I had a similar trouble while building qt3.3.2 with MinGW 4.5.
  To resolve the error ‘QAxServerBase’ was not declared in this scope,
  move the QAxServerBase class definition (found in qaxserverbase.cpp) above the axServerMapper() declaration.

  Hope this helps.

  Wrong code was:
  @QSqlDatabase db;
  db.addDatabse ("QMYSQL");@
  which I corrected to
  @QSqlDatabase db = QSqlDatabase::addDatabase ("QMYSQL");@
  This solved the problem.

  Yours

  It should be the same as the downloadable source package, right.

  If it still goes wrong, I would recommend to open a bug report on the "bug tracker":http://bugreports.qt.nokia.com

  [quote author="Andre" date="1300082792"]
  As far as I know, this layout is incorrect: the PlugIns directory doesn't belong there. Instead, the different plugin directories go directly into the application dir. At least, that is how I distribute my applications on windows, and that works.
  [/quote]

  We have to ship some other plugins too, it would clutter the toplevel directory, so we decided to put it into that subdir. An we use the QCoreApplication::addLibraryPath()[1] approach, so it does not harm. With the default settings there is too much guessing where the plugins are located, we think this is the most robust way.

  fn1. use this for the path:
  @
  QCoreApplication::addLibraryPath(QCoreApplication::applicationDirPath() + "/PlugIns");
  @

  This is a special version to include the moc code. All QObject based classes must be processed by the moc tool ("meta object compiler":http://doc.qt.nokia.com/latest/moc.html). In regular qmake project, the moc files are added to the source file list automatically behind the scenes. The are then included in the Makefile and the object file list for the linking stage. Instead of compiling the moc generated files manually, one can #include them into a regular cpp file too. This is what happens in your case.

  you can also download the Qt source package from here: "downloads":http://qt.nokia.com/downloads

  Unable to static compile Qt 2010.05

  I'm new to QT so take that with a grain of salt. Here's how I got the darned thing to appropriately run configure.

  I'm using QT4.7.0 on WinXP Sp3

  Create a user variable:

  QMAKESPEC = "win32-g++"

  Create mingw_home user variable:

  MINGW_HOME = "c:\qt\2010.05\mingw" <-- NO BACKSLASH!!!

  Add the mingw variable to my user path:

  Path = "...;%MINGW_HOME%\bin;"
  (For whatever reason the post isn't placing my percent signs in front and behind my MINGW_HOME variable.)
  Then restart my command prompt and run config -static inside the "c:\qt\2010.05\qt" folder.

  Ultimately, the ming32-make fails with the message "undefined reference to _imp_Z.... I'm going to try compiling from sources instead. I'll give more feedback later.
  I hope this helps someone.

  [quote author="Volker" date="1299070034"]Why should it not be possible? It's just another case of cross compiling. Notice, it's all about building, not running the libs :-)

  If you use MinGW the make command is "mingw32-make". But you need a MinGW compiler that can create 64 bit code. Probably you must install a special version of gcc, because it could be that the regular 32bit compiler does not support this cross compiling out of the box.[/quote]

  Thanks!
  I agreed Volker’s point of view: “Only build, not run.” I download MinGW-w64 cross toolchain, I not see the 32bit and 64bit command prompt, only “MinGW command prompt”. Not like VS have: 32bit: “visual studio 2008 command prompt” 64bit:“visual studio 2008 ×64 command prompt”.

  And unfortunately, I follow the steps of how_can_i_build_64_bit_qt_on_a_32_bit_system [developer.qt.nokia.com] , but not success. My steps:
  Qt

  Download :qt-everywhere-opensource-src-4.7.1.zip, release to D;/QT/4.7.1 Setup VS2008 (include x64 toolchain)
  3: Go to “visual studio 2008 ×64 command prompt”, step into QT dir
  4: Use “configure -opensource …..-platform win32-msvc2008|” the 4 step is success, but when use “nmake”, pop the error messagebox: qmake is not a valid win32 app.
  I know at 4 step, build 64 bit QT tools, these tools cannot running on 32bit platform.
  But how to build 32bit qt tools( moc.exe , uic.exe qmake.exe, rcc.exe etc.)?
