Failed to start program. Path or permissions wrong?

clouca

i deleted the .pro.user and made the configuration from the begining and still the same error. i don't want to play with shadow building because i don't want to loose my backup. another idea?

sierdzio

Check console output when doing a full rebuild - maybe linker has problems in writing the output file?

clouca

Thanks for your fast answer.. Where can i find console ?

sierdzio

Hit Alt-4 in Qt Creator, or click on "Compile Output" button at the bottom of Qt Creator's window.

clouca

Yes i get an error there..
make[1]: Entering directory ....Desktop_Qt_5_0_2_GCC_64bit-Debug' make[1]: Nothing to be done for first'.
make[1]: Leaving directory `...Desktop_Qt_5_0_2_GCC_64bit-Debug'

i hided the full path for obvious reasons.. :)

sierdzio

That looks like shadow building in works.

"Nothing to be done for 'first'" is standard make message. It's not an error as such - usually it means that the project is already built and there is no need to compile again.

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".

clouca

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.

clouca

thanks
