OK, my application works fine now, but when I try to build it in release mode, the compiler terminates with an error. It says an unknown software exception occurred. That really stinks because I was just about to put the final executable with the dlls and see how it runs.
it's probably caused by accesses to some unexpected addresses (e.g. index of array out of range)
debug version usually doesn't have a so strict mechanism as the release version
please do more checks to your code
I don't understand. Wouldn't an index out of range cause a runtime error, something that can only occur during the execution of the compiled program? I didn't even get the program built yet. The compiler itself terminated before it was built. But it works fine in debug mode.Quote:

Now I don't understand how my code could have caused that. But I know you are more experienced and know more. So I just need help understanding what's wrong here.
What version of gcc are you using (MinGW or Cygwin, and what version exactly)?
Is there anything that compiler outputs before this error occurs?
What version of Qt are you using?
Please write the exact procedure you do to compile your program (commands you enter) if you are using command prompt.
I'm using Qt 4+ and whatever compiler comes with QtCreator.
1. I load my project in Qt Creator
2. I click Build > Set Build Configuration > Release
3. I click Build > Build All
Then it says this:
After which it displays the error message in my earlier post.Quote:

Error while building project Learning
When executing build step 'Make'
Try using Qt 4.6 (it seems that you are using qt 4.5), maybe mingw bundled with previous versions was incompatible with Windows Vista.
Also try compiling your project from command line. Launch Qt Command Prompt (should be somewhere in your Start menu), enter your project's directory (cd "C:/Users/Guido/Documents/Learning/"), run "qmake -spec win32-g++ -r CONFIG+=release" and "mingw32-make -f Makefile.Release". If that doesn't make any difference, try to run just "qmake" without any parameters, and then run make command (the same as before).
It works. Thank you.Quote:

Why not use qmake? You'd have to write all build rules (including rcc, uic and moc) in a different build system (cmake, automake or (hard core) a Makefile) yourself.Quote:

However, qmake makes some assumptions when generating makefiles, for example it's configured to use gcc as compiler by default, so if somebody tries to compile your project using generated makefiles, he might have to manually edit it if gcc is not installed. In this case the best way is to use 'configure' scripts, but I've never used them, so can't really help, sorry.
