Failed to start program. Path or permissions wrong?

clouca

heh that's the problem, the project did not create and executable... in the folder there are only 3 files Makefile Makefile.debug and Makefile.release..

sierdzio

Delete those makefiles.

But we're running in circles here, I'm afraid. I'm sure I've run into a similar problem before, but I don't remember what was the solution. We're probably missing something obvious.

clouca

Yes i know that we are making circles. I will try now removing these make files.. please remember :)

clouca

i made a backup of whole project and remove shadow build and works. but i don't think that is a solution.
it is a semisolution i think..;)

clouca

it was not a solution finally. the project always executes the old executable file. the problem is that Qt builds successfull but the executable file is not created...

Hi,
in this case, are you sure your project is setup correctly ? Could you share the pro file ?

This may be similar problems as I had lately. However, I am on Windows 7 with creator 2.6.
I have a rather large project based on subdirs with some libs shared by a couple of applications.
I noted that changing the source with some debug statements and in the debugger there was no influence on what I had changed. As I found out later Qt creator compiled and linked always the release version only for this particular application. I did the whole bucket of things rebuild, clean and build (as separate steps) also at least some partly "Run qmake" until I found out what happened. In my case it was cured by "Run qmake" for the whole subdirs project. Suddenly the debug build was created.
It sounds a bit weird, but I assume Qt creator somehow looses track when switching between release and debug modes. IMO not really a logical behaviour, but I do not know what is actually happening in qt creator.

Especially if you have a complex project, try "Run qmake".

Yes it's very weird.. I am thinking to switch it in windows for better luck. I run linux on virtual machine, does this make any difference ?

Do not know. I have not used Qt creator lately on a virtual machine.

at clouca: that is an option. Maybe someone sees an issue.

Do you have a complex project?

clouca

Yes it is a project with 5 subfolders..

SGaist

Since it's a subfolder project, how do you setup your DESTDIR variables ?

clouca

Thanks all of you for your answers. SGaist I will check tomorrow and tell you.
Thanks

Hi
I had this problem in old versions of QtCreator. As far as I remember it's a bug, but is was supposed to be solved in latest version, I believe. Do a google search, you will find similar threads some wich are alreay solved.

Those are the versions of Qt lib. Qt creator has currently version 2.7. A Qt creator installed with Qt 4.7 is fairly old.
How did you install Qt 5? Which exact Qt5 version are you using? Did you replace also the Qt creator at that time?

clouca

I use Qt Creator 2.7.0. Based on Qt 5.0.2. No i didn't replace anything, i moved to a new pc to startover the project.

clouca

as i have noticed i have wrong path. but in the correct path the executable does not exists. firstly how can i change the path ?

SGaist

Where does that path come from ?

clouca

I don't know what to do i am desperated...

SGaist

Do you set the DESTDIR in your pro files ? If yes where do they point to ?

Otherwise can you post (i.e. pastebin) your pro files ? So we can see if the problem lies with them or if we can eliminate that as a cause.

Did you take a look at the build panel to see where things are built ?
