Qt Creator doesn't stop at breakpoints ?

[edsonmcz]

I haven't problem in coding and compile my programs in QT Creator, but when I try use debugger in my code with breakpoints, Qt Creator doesn't stop at breakpoints.

I already tried a search in internet, but I don't found the solution for my problem.

If someone can help me, I thanks.

Make sure you build your project in debug mode.

[edsonmcz]

I have sure about this

Exit QtCreator,
Delete shadow directory,
delete *.pro.user file in your project directory,
Open the project and build it in debug mode.

Set a breakpoint somewhere in the main() to test.

The same is happening, I really don't know what is this, I searched in the internet, but I don't found something about this, I think my installations is correct.

I followed this tutorial:

http://labs.qt.nokia.com/2007/07/11/develop-qt-applications-in-eclipse/

Thanks a lot

Looks like he is using eclipse and not QtCreator so we need someone with working knowledge of eclipse...

[Spitfire]

Are you using Eclipse?
Then the title and what you say is at least very misleading if not wrong...

[edsonmcz]

No, I just use QT Creator, I have never used Eclipse for QT.

This just happened in QT Creator.

Sorry, I don't have explained correctly, in the true I used just this site :

http://qt.nokia.com/downloads

I tried use Eclipse but :

Which platforms are supported?
The plugin runs on Windows and Linux x86. Debugging does not work on Windows x64, because GDB crashes, there. OSX will be supported in a later release.

[Spitfire]

So why you followed Eclipse tutorial? Odd.

Anyway, what system are you using?
MacOS X as it's stated in your details?

So, are you making a debug build? Are you running it from inside of Qt Creator using the Debug menu? Can't tell anything from your screenshot.

[Spitfire]

Create new, empty, console app project, save it on main mac partition (not the second drive you're using now - just to be sure), set breakpoint in main, build and debug.

Check application output/compile output for any issues - ie missing gdb.

Thanks for all

Your idea worked, I create a Empty project and all worked perfectly

I thought this problem was occurring in every projects, but wasn't

Thanks a lot :D

I have this problem an nothing this solve. Someone could helpme? My project is a debug project but the gdb dont stop in any breakpoints.

[Spitfire]

You could at least say what you've tried, what's your OS and so on.

It's still quite difficult to read minds...

[Júlio Brito]

ops, im sorry...

My problem happens in win 7 64. I put a breakpoint in a line, but gdb dont stop in it. The program runs and ends normally without debugging. My project is configured to debug and all path is correct.

Here is the output of debug log comand:

I have the same problem although it's probably because my Qt creator is set up to build with msvc tools, but tries to use gdb.

[Júlio Brito]

I ill share my experience in the last week and how i can solve this problem. I was using the " win7 terminal" or "console" from qtcreator to run and debug a application. I've change in the "run options" to dont use the terminal and print the results in qt creator ide. This solve the problem. I could see that is a issue with qt creator and win7 terminal.

perhaps this can be a issue to be reported.

Thanks for help.

I have been seeing this behavior occasionally: Breakpoints work for a while, then stop working, what I have to do is delete all breakpoints, restart creator, re-run qmake and put them back and rebuild in order for them to work. I haven't figured out what causes this to occur or if this is an overkill solution but this is what I do.
