Qt Creator only builds the Release version!

[Verse]

Installation: Qt 4.6.0 (Mingw) built Nov 27 2009 (LGPL)

I installed it, did the tutorial for TextFinder and I am having some real build issues.

The default build configuration is Debug. The build is green but when Qt Creator tries to run the TextFinder app I get...


Starting H:\Cookbook\qt\text_finder\debug\text_finder.exe.. .
The process could not be started!


Looking at the actual directory, I find that the \debug directory is empty but that there is a text_finder.exe in the \release directory. Running that .exe yields an error message box - "text_finder.exe - Entry Point Not Found"...


The procedure entry poin _Z21qRegisterResourceDataiPKhS0_S0_ could not be located in the dynamic link library QtCore4.dll


So, I switched the build configuration to Release, and everything builds and runs just fine.

Switching back to Debug and examining the compile output reveals that even though I have selected the debug configuration the Makefile.release is still being used to build the project, here is the output of a rebuild with the Debug configuration...

I have other, commercial, installations of Qt installed (and usually have no problems with them but they are for VS2005), I also already have Mingw and Msys already installed and on my path.

Any ideas?

Do you have debug versions of Qt libraries (they should have a "d" character appended to their name)?

[Verse]

I think so, the DLLs look like this...

./qt/bin/QtCore4.dll
./qt/bin/QtCored4.dll
./qt/bin/QtGui4.dll
./qt/bin/QtGuid4.dll
etc...

So, I assume that those with the extra 'd' are the debug versions.

[wysota]

Create a (new) minimal project containing only the main() function and see if you can build it in release mode.

[Verse]

Created a minimalist 'Hello World' main.cpp - same issue. However, I can build from the command line with "make release" or "make debug" and that works fine.

[wysota]

Please post your qmake project file of the minimal example.

[Verse]

I have attached a tar.gz of the project, plus the generated makefiles.
