Can't run program from QT Creator says it exited or Cannot obtain a handle to the inferior
-
When I try to run my program it either says it exited with code 0 or it says Cannot obtain a handle to the inferior: The parameter is incorrect. I can take the built exe and run it just fine without QT Creator. I tried rebooting my pc, close/reopen QTCreator, building with different compiler, and cleaning the project.
What's going on here?
-
Once i had faced a problem like this... I just did like this.. go to Projects, and check your Qt Version and Tool Chain properties and change it to your needs... Then it worked fine for me... :)
-
The tool chains and things are set up, it builds just fine. And the exe it builds when run from the folder directly runs fine. But QT doesn't run it.
-
Does it says that any dll's required??
-
I deleted the build folders and the .user files, still doing the same thing after restart.
-
No, the .dlls are fine. Strangly I installed 2.6rc and it worked after setting up the kits, it built and run it fine a few times and now im getting the same error again.
-
I've uninstalled and reinstalled everything QT and still getting this problem. QT is not usable like this.
-
I have the same problem. Qt 4.8.2 + Qt-Creator 2.5.2 under WinXp.
I ran into it in two projects: both console and finishes very quickly. One of them is a test project, the other - a console project, which does not call QCoreApplication::exec() (I checked a project, which calls it - no problem there).
After rebuilding - first launching finishes well. In all others qt-creator thinks that the program is still running (and writes "Cannot obtain a handle to the inferior" in debug console) though actually it does not.
It is annoying. -
Hi there,
is there any solution to this problem?
I observed the same problem here, but the message only occurs during my QTest's.
I assume that the QTEST_APPLESS_MAIN sometimes runs into that error-message.
It seems to correlate with the presence or absence of a QCoreApplication, because if i use the same code within my Console-application the message never occurs.
Also Amartel mentioned, that his project using QCoreApplication runs without problems...Should one file a Bug-Report here?

I see the same on Win7 using 5.0.1. For me there has been nothing but errors with 5.0.1. For instance debug/release paths are mixed up when building, this error, uic seems to create invalid ui_foo.h files etc.
-
If you go to Projects -> build & Run and then check the Run settings, make sure that the Executable being called in the Run configuration is the same one for the build configuration e.g. ./debug/<your_app.exe> (use absolute path) for a debug configuration
-
There have been a few related issues. I had the "handle" issue among others when moving to 5.0.1. I resolved using the following steps.
- Clean project
- Close QtCreator
- Remove Release/Debug Folder from app directory
- Delete xxx.pro.user file (lives in app directory)
- Manually delete Makefile, Makefile.Debug, Makefile.Release (If still there)
- Open Qt Creator again and open your project. It should now be asking you to reconfigure your project build settings.
Also, check your environment variables – ensure they are updated for 5.0.1 paths.

Thanks Wakeuky for step by step reply.
It is not working in my case.
I could debug/run my project; made some changes in the code and then this error appeared.
Can there any other reasons for this problem? -
Hi tesmal4, it has been quite a while since I have seen this issue. This issue occurred for me when I had created a project under the 4.8.4 environment and tried opening the project under 5.0.1.
I am no using the latest 5.1.1 release and have had no issues of the sort. What version was your project created under?
What version are you currently trying to use? -
Qt 4.7.4 for Desktop MinGW 4.4 and Qt Creator 2.4.1 . I did not change any configuration for the project. I only made changes in the cpp file.
-
I accidentally deleted DLL path. Now its working fine.
Thanks for your help and advice.Regards
-
teslmai4: I have the same kind of problem with Qt 5.5.0. Can you please indicate what DLL path you delete?
-
I have same issue.
And I copy my own DLL file to app-out-dir.
then this issue can to solute. -
Seems likely that it is not a real "problem" but can be due to your application exiting too quickly when being run under QtCreator, please see this link
