Including 3rd party software makes my program crash with QFileDialog

**ruben.rodrigues** · 24th January 2011, 11:53

I already posted the problem in another thread but I didn't get answers.
I know it sound crazy impossible but if I had the -halcon include it doesn't work (terminates with segmentation fault) and if I take the include it works just fine.

It is no problem with my code to open a file dialog but because I have to use the halcon library I would like to know about other way to open a file browser, please.

thank you.

Please provide a minimal compilable example reproducing the problem.

I am not trying to solve the problem because I already lost too much time trying to solve this and I couldn't find the solution. I have other thread where I tried to solve this situation here.
Off course I would appreciate if someone reproduced the problem in their computer but that's probably asking too much. You would have to download Halcon 8.0 and include it as I did in any qt project and you see that you can't use the QFileDialog anymore.

Do you know other way of opening a file dialog or do I have to find a magical way of solve this problem.

thank you.

Patience is a virtue. Provide a minimal compilable example, run it and post the backtrace of the crash. Then we can talk about it. I don't know what this Halcon lib does but until we know why your code crashes, there is no point in blaming anyone.

By the way, threads merged.

Can you just tell me, please, if there is another known way to open a file dialog?

You can always use the native API. Of course this is the same what Qt does when you use the static call (which you probably do) so it's likely you'll end up with the same result but since you really want to waste time, I'm not going to stop you. When you decide to come back for more help, please be sure to bring a backtrace of the crash with you.

is the backtrace the DSF disassembly on Eclipse for ubuntu?
