:-1: error: [.depcheck-impl] Error 255

nulluse

Also now that offline installer is installed, I can no longer add or remove packages with the maintenance tool (which does not exist in the start menu anymore, I am launching it from the Control Panel/Programs and features) as instead it displays an error:

At least one valid and enabled repository is required for this action to succeed

Microsoft is the only provider of Visual Studio, you can only get it from them. It has always been so way before Qt Creator was written.

Qt Creator is "just" a cross-platform IDE that offers a nice environment that you can get familiar with and will stay the same across OSs. It will use whatever the platform provides as compiling environment. Qt's always worked like this.

If you want to have a Qt package that comes with a compiler then use the MinGW version.

The online installer allows to select several version of Qt, which might be useful since Visual Studios versions are not compatible one with the other i.e. a library build with VS2013 can't be used with VS2015 and that's nothing Qt specific.

On a side note:
The OS X package also doesn't provide any compiler since Apple provides Xcode.
The Linux package also doesn't provide any compiler since the Linux distributions do it.
Same goes for Android and iOS.

nulluse

MingW is checked off by default when installing online package, yet still all the errors above and nothing works.

nulluse

Fuck! There is a second check box for MingW down in the Tools and it was off by default.
This cannot get any more confusing. Who is the cretin who disabled compiler install by default?

I would suggest you to stay calm and read forum rules so you are not banned for breaking them
unless that is what you are trying to achieve.
Be nice and you might get another advice on this forum. This is your choice,

As for your valuable thoughts about default options I think you are wrong.
All installation of Qt is expected to do - is to install Qt.
Say thanks it installs binaries and let you avoid building library on your own.
If it may do something extra and may install the compiler which it capable to install legally - it is extra.
Not everybody needs this compiler. Not everybody wants it and who want probably already have it on their systems.

Hi
Besides the all-in-all installer you can also download directly what u want
https://www.qt.io/download-open-source/#section-2

I always use
Qt 5.6.0 for Windows 32-bit (MinGW 4.9.2, 1.0 GB)

Since I dont use visual studio support.

So there are all options to match different users needs.

nulluse

How is the user expected to know which of two identical options installs the compiler?

Hi
What identical options ?

You select the precompiled packet you want - for a given Qt version.

Then you also have the option to install a mingw compiler if wanted.
There is no visual studio here as MS forbids it. (sadly)

Its not enabled pr default as most programmers get really angry
if a new compiler is installed pr default and mess up the settings for the already installed one and working one.

nulluse

You should expand the first child of Qt - Qt 5.6, then you will see checked off by default MingW 4.9.2
Then there is identical check box under Tools called MingW 4.9.2 which is unchecked by default.

mrjj

@nulluse
The first one is the Qt packet. the precompiled Qt. Its not the compiler. its indicates what
compiler its compatible with. Its Qt for different platforms. precompiled. :)

nulluse

It is great when you know that. But if you do not, they are identical and it is not clear whether the 2nd one should be checked off.
This is called confusing UI, if the packager was going out of their way to make installation confusing and counter-intuitive, they excelled at that.

mrjj

well, now that you know it, does it work for you ?
