bulid wouldn't start before indexing has finished.
seems like u have too many dependencies in your project. take a look at compile output.
Re: Unacceptable build time
So you effectively suppose that compiling a relatively simple example Qt application can took 1 hour. That's an absurd.
I tried to post the Compile Output verbatim, but I got an error:
"The text that you have entered is too long (12991 characters). Please shorten it to 10000 characters long."
So I made the following substitutions to shorten it:

Of course not.
Building such a simple application takes only a second.
Does it take so much time for eveything you compile in Qt Creator?

Today I compiled the Drag and Drop Puzzle Example - it took 30 min (14:16 build started, 14:46 build ended).
Yesterday I compiled the Colliding Mice Example - it took about 57 min.

Re: Unacceptable build time
I tried to compile the Elastic Nodes Example - it took about 76 min. During most part of this time Qt Creator:- does not consume noticeable amount of CPU resources.
- very slowly consumes additional memory.
- does not start processes - I watched it in Process Explorer.
- does not record activity in the Compile Output except for the message:
"Running build steps for project elasticnodes..."

I don't see how the CPU time of Qt Creator (which depends on the used CPU) implies likely problem in g++.
The g++ version is: gcc version 3.4.5 (mingw-vista special r3).
Is there someone in this forum who can give more rational suppositions?
Re: Unacceptable build time
I had one, but the insults being slung by someone ostensibly looking for help made me decide to keep it to myself.
Re: Unacceptable build time
I found a reason for the delays and filled two reports about this. When running Qt Creator with Normal priority some of its threads run with Base priority 1 (which corresponds to Thread priority level THREAD_PRIORITY_IDLE). This means that the threads of other processes will likely have higher priority (even threads belonging to Low priority processes). So if there is computationally intensive process it will likely block or severely delay the Qt Creator tasks performed by the low priority threads (e.g. Parsing and Indexing tasks). This scenario is more evident on single core processors.
The system can increase the priority of threads by changing their Dynamic priority (which never falls below the Base priority), but this is subject to conditions and it may be disabled.
This screenshot (obtained from Process Explorer) illustrates the problem:
A workaround for this issue is to increase the priority of the affected threads for example with SetPriority from http://gilchrist.ca/jeff/ as follows:
- Obtain the PID of the Qt Creator process (<PID>) for example with:
tasklist /fi "ImageName eq qtcreator.exe" - SetPriority.exe -t0 <PID>
- If Qt Creator stops again go to step 2
The second step will set the Thread priority level of all Qt Creator threads to THREAD_PRIORITY_NORMAL. To check the priority of the Qt Creator threads: SetPriority.exe –g <PID>
If particular Qt Creator task appears stagnant and there is a thread with priority -15 try step 2.
I do not guarantee that the above procedure is safe – if Qt Creator freezes permanently or crashes (although in my testing this didn’t happen) and you lose a work as a result of this I am not responsible.

A possible reason to feel offended is the possibility that you had nothing worthwhile to add to the issue. Another possible reason is that you care more for the group in which you belong and your place in it than Qt Creator.
