Hello,

I have downloaded and installed Qt 4.6.3 SDK for Windows from
http://qt.nokia.com/downloads/.

When I tried to Build the Visual Studio Project after 'qmake
-recursive', it keeps looking for QtOpenGL.lib, QtGui.lib, whereas the
library files that come with Qt 4.5.x onwards have a '4' appended to
the library name. So QtOpenGL.lib is now QtOpenGL4.lib and so on.
Similary, qjpeg.lib is now qjpeg4.lib.

I went through every project and fixed the library names to look for
Qt*4.lib, but when I ask it to look for qjpeg4.lib, it gives me the
following error.


 Creating library Build\ImageVis3D.lib and object Build\ImageVis3D.exp
2>main.obj : error LNK2001: unresolved external symbol "class QObject
* __cdecl qt_plugin_instance_qjpeg(void)"
(?qt_plugin_instance_qjpeg@@YAPAVQObject@@XZ)
2>main.obj : error LNK2001: unresolved external symbol "class QObject
* __cdecl qt_plugin_instance_qgif(void)"
(?qt_plugin_instance_qgif@@YAPAVQObject@@XZ)
2>main.obj : error LNK2001: unresolved external symbol "class QObject
* __cdecl qt_plugin_instance_qtiff(void)"
(?qt_plugin_instance_qtiff@@YAPAVQObject@@XZ)
2>Tuvok.lib(IASSConverter.obj) : error LNK2001: unresolved external
symbol _gzdirect
2>Build\ImageVis3D.exe : fatal error LNK1120: 4 unresolved externals


Please could you recommend whether I should just try renaming all the
.lib's and .dll's in the Qt lib directory or whether I should try and
do this in cygwin. Thank you.

Regards,

Alark
