Problem regarding building even an Qt example.

@Jhanvi did you read the red error output?

it cannot create a directory as it seems you dont have write access there.

try copying the example to a writable location and try again.

edit: other possibility: the path to the build folder got messed up.

Jhanvi

I did not clearly understand what you are trying to explain . Could you please elaborate with more detailed steps. And also how to make sure the compilers are detected properly and assign the kits as you mentioned earlier ?

@Jhanvi

From your screenshots I can see that you already changed some configurations; that may be a root of the problem.

You installed Qt for MSVC2017 but not MSVC2017 compiler (and therefore probably the red exclamation sign in Kits)
You added manual compilers which I guess are not needed
You changed the default build directory in the third screenshot, therefore the warning "The build directory needs to be at the same level as the source directory"
You get a red error in the second screenshot: "Could not create directory [...]" This is probably because you don't have write access to that directory

Point 4 is the critical point here; it's impossible to build if directories and files cannot be created. Can you try to create a new project in a directory you surely have write access? I assume that building with MinGW will work then.

So please tell me how should i check that i have the write access to it and if please provide me the steps to do the same.
I am trying to run a simple qt example but still it is showing me the same error and hence i can not build any of my projects please help me with it.

@Jhanvi You probably installed with admin permissions to that directory and you are trying to build with a non-admin/elevated user.

So it can not create the build directory it needs because of the permissions on the Qt install.

You can change the permisions, right click->properties in explorer, use the attrib command on the command line, etc.
You could copy the example out into a directory you do have permissions to, i.e. c:\users\youruser\qt-examples and then open and build from there.
You could run qt creator as admin

I recommend #2... #1 and #3 can be dangerous, so I wouldn't go that route, but it's an option.

Jhanvi

Now i am getting it as no rule to make target all stop.
What should i do ?

aha_1980

@Jhanvi please close Creator, delete the *.pro.user and then open the project again.

Jhanvi

where is the .pro.user ?

ambershark

@Jhanvi In the root directory for the project you are building. At the same level of the .pro file.

Jhanvi

Still the same error.

@Jhanvi Post the actual build log so we can see what really went wrong.
