Hello guys i installed qt 5.5.0 successful, but there is this permission errors which are raised when i was accessing any files in /opt/qt directory. It is the dir in which qt is installed.
And i get "no write permission error" too. I know i need to change permissions but i dont know which dir or files to change permissions of.
So please help me to avoid his permission conflict. -
Hi and welcome to devnet,
Where do you get that error exactly ? What where you trying to do ?

I just opened qt 5 from the applications menu. So qt will be opened by the user but not root.
I wanted to have a look at inbuilt examples so i headed to examples tab and clicked on a example after which i got a notification saying i dont have write permission for /opt/qt5.5.0 . -
Go to the project panel and check the shadow build path. It's pointing to something like /opt/where_the_example_is_located/build-MyExample-Debug_etc. Change the path before build-MyExample-Debug-etc. to a place where you can write and you should be good to go

-
Did you re-run qmake after changing the path ?

@SGaist Do i have to run qmake in terminal or is it a equivalent of build?
-
You can do that from the Build menu.
No it's not the equivalent of a build, qmake is a project manager (like cmake, QBS etc.). It set things up for you so then you can do builds.

Which header is missing ?

@SGaist /home/nishanth/gallery/main.cpp:41: error: qtquickcontrolsapplication.h: No such file or directory
Dont you think all these issues are because of permission issues?
-
No, it's not a permission problem. Seems like you moved some stuff around that find is in qtquickcontrols/examples/quick/controls/shared

The path "/home/nishanth/gallery/main.cpp" doesn't look correct gallery should be in qtquickcontrols/examples/quick/controls/

When i select a example it gives a notification saying this [IMG]http://i62.tinypic.com/2h5u3p3.png[/IMG]
After which i makes a copy at /home/nishanth -
Ok, then you need to also copy the "shared" folder at the same place.
I though you only changed the shadow build path not copied the whole example

I had to copy the contents of shared folder "Examples/quick/control/shared" to the example folder in my home directory.
Here home directory is set as my project directory.
Ty very much for helping me.
But dont you think all these should work out of the box? -
AFAIC Qt Creator assumes that examples are self contained. These are a bit of a special case
