Could not start Application ....missing qtcored4.dll......

[donglebob]

Hi,

on my Windows XP Pro system I installed QT 4.4.0 + VS 2005 (incl SP1).

I configured QT with this:

configure -platform win32-msvc2005 –no-qt3support

and compiled it with

nmake

Environment Variables which were added/edited by me:
QTDIR = C:\QT4
LIB = QTDIR\lib;
INCLUDE = QTDIR\include;
Path = QTDIR\bin;

Settings in VS 2005:
Tools-> Options -> Project and Project Solutions -> VC++-Folders

Executable Files:
$(QTDIR)\bin

Include files:
$(QTDIR)\include
$(QTDIR)\include\Qt

library files:
$(QTDIR)\lib


My Problem:

When I compile an example from the QT folder, it proceeds without problems.
No Errors, no warnings.
When I start the compiled application I get an error.
It can't find the QTCored4.dll .
It doesen't matter whether I compile in Debug or Release mode. I get these errors.


What could be the problem?

The missing files (and others) are located in my C:\QT4\lib !!!
QtCored4.dll
QtCore4.dll
QtCored4.lib
QtCore4.lib

Restart Visual Studio after modifying environment variables.

How do you start that application?

Ok I found my mistake.
The mistake was in the environment variables.
I forgot to use % around some keys.

Heya I fixed this problem in the same way, but what should I do if i start the program on another pc without having QT installed?

You will need to ship the required qt dlls along with your binary.

[T1c4L]

is there an another possible way to do this? Without shipping Dlls to your .exe?

Im using the licscensed version of QT.

These are the following steps i have done so far:

Installed VC2005+SP1
Installed qt-win-commercial-4.4.0-vs2005.exe
Installed qt-vsintegration-1.4.0.exe

Now I was able to create QT projects within vc2005 project wizard.

I created a gui application. compiled in release mode.

Now how do I deploy this application to another pc but without providing qtcore4.dll and qtgui4.dll?

You will have to compile Qt as a static library.

Try a system restore, if that does not work backup your saved games folder, reinstall the game and launch it. If all goes well you can copy your saved game data back into the saved game data folder on the new install and pick up right where you left off.
