[Solved] How can I add a compiler?
-
Did you install the MinGW build of Qt ? If not, then then that's the first thing to do

Hello Rela and welcome to devnet,
it would be easier to install MinGW using the 'Qt Maintenance Tool'. You can find it in your Qt folder. It's name is "MaintenanceTool.exe". Just start the tool and select "Change" or something like that. Afterwards select the Package "MinGW" (you might find listed under your Qt Version). Then just continue with the installation and when it's done you can configure your project inside Qt for MinGW.
And just for interesst: why don't you want to use a newer version of Qt? Is it because you are trying to run an older qt project and you have concerns about compatibility?

Hi and thanks.
When I click on "Maintenance Tool.exe" it asks some setup questions:
"Add or remove components"
"Update components"
"Remove all components"
Which one should I choose?I installed Qt5.4, and the newest one is 5.5. I am not going to run an old project, just want to start developing an GUI for a C++ algorithm in MVS 2010. May I ask what is the advantage of the newest version?

Which one should I choose?First of all you might click "Update components" and check if the MaintenanceTool needs an update - if so: update it. After you updated the MaintenanceTool you have to restart it. Then click on "Add or remove components". That's the part where you can modify or change your current Qt Setup. Since you're using Qt 5.4 you just go in the entry 'Qt 5.4' and then select the ackages you want - in this case: MinGW(newest version of it). Then press "continue" or something like that. If you want to update to Qt 5.5, you will have to deselect Qt 5.4 and select Qt 5.5(just the packages you want/need).

Then you might want to check the new Features in Qt 5.5 . If your algorithm was written to work with the mvsc2010, then you might want to keep it that way. You can install MSVC on your computer and afterwards install the MSVC package in your MaintenanceTool just like you did with MinGW.

Thanks for your complete explanation.I chose the MinGW in the list for Qt5.4, could you tell me if I need choose more components?Maintain Qt
I have the C++ algorithm in Microsoft visual studio 2010 and it has been installed already. Can I work with Qt5.4 while I have MVS2010?
With respect to the MSVCs that are marked in the list are 2013. -

Depends on what you need. If you want to develop for Windows (x86/x64) only, then i would recommend to select the following packages only:
- Qt 5.4
-
- MinGW 4.9.1(32 bit) OpenGL <--- maybe???
-
- msvc2013 32-bit
-
- msvc2013 64-bit
-
- Source Components
-
- Qt WebEngine
- Tools
-
- MinGW 4.9.1
Keep in mind [!]: The compiler comes with the visual studio! That means that you will have to install the appropriated Visual Studio version. Example: For msvc2013 you'll need Visual Studio 2013. Lets take the selected packages - in the case above: msvc2013 32-bit and 64-bit. These are just pre-build components! This package doesn't contain the compiler.
You can see MinGW 4.9.1 under Tools. It's the full MinGW Toolchain(containing the compiler). So for MinGW you won't need to download the compiler from third-party(like visual studio from microsoft).
Under Qt 5.4 you can see MinGW 4.9.1(32 bit) OpenGL. These are also just the prebuild qt-components for MinGW.
Qt WebEngine might be interesting for you since your project-name was "YouTube".

I might be wrong with my informations since i'm just a beginner myself. But still: this might be correct and get you started. :) -
Thank you, your help is so helpful, since from last week I am just involving with this compiler problem.
I see 5 marked MSVC2013 for 64 and 32, how to know which two ones I should choose?MSVC components

You can imagine it that way:
Qt is just here to help you develop applications. It has a large amount of classes you can use and the qt creator(the gui which helps you develop applications with qt). It's far more - but let's keep it simple.
If you want to compile an application for an platform, then you'll need an compiler which can compile it for that platform. For windows, microsoft provided an compiler which is included in the MSVC(Microsoft Visual C++) package.So lets say you want to compile for windows: You'll need MSVC. Afaik Qt isn't allowed to put MSVC into their installation, so you'll have to download and install MSVC on your own.
Theoretically you can compile a Qt application for windows now. But it would take a very long time to compile all the qt code from the Qt classes you use because it's a large amount of code. Therefore you can download the precompiled qt classes. That means some guy compiled them using an compiler for a spezific platform (lets say MSVC for windows) and put them free for download. So if you download these packages you won't have to compile them a second time!
I hope i could explain it a bit. I cut a few steps and informations but i tried to keep it simple. :)

If you read it again you'll see that it isn't msvc2013 only. It has also packages for msvc2012 and msvc2010! It has also msvc OpenGL packages - which you won't need now(i guess).
I would take the newest:
- msvc2013 32-bit
- msvc2013 64-bit
Select the ones without OpenGL.

To understand the precompiled-package part you might want to check out this wikipedia-link:
Just read it a bit and it might explain you the purposes of Dynamic-linked libraries(DLL). The precompiled-package contains DLLs. :)

Thanks onek24. I just chose 2013 ones without OpenGL, now it works.
The MinGW was among the removed components when I was installing Qt, since It took a lot of space, I removed some of them.I am working with Qt5.4 vertsion and MinGW compiler now, but could you please tell me if I want to develop interface for the algorithm in MVS 2010 later, what I need to do? I think one way is installing MVS2013, but if I want to keep MVS2010 what the other option is?

You're welcome. Afaik you don't need MSVC if you work with the MinGW compiler. If you installed Visual Studio and the corresponding MSVC-Package in the MaintenanceTool, then you can compile with the MSVC compiler.
I'm sorry but i'm currently not understanding in what form the algorithm is. Do you have the source-code or what is it? Please explain a little bit further.

So your algorithm is just c++ code you want to implement? Since Qt can detect your compilers, you have already installed MSVC. Please go to the section "kits" in the "settings" -> "build & run" and show me whats listed. If you can find something named "Desktop MSVC"(or something like that) then you can compile with the msvc compiler. If you go to the bottom left, you can see "Bucky 4" and below it "Debug". Click on it and select MSVC if you can find it. If you can't, then go to "Projects" in the big left menue and add the Kit "MSVC".

@JKSH said:
One thing to keep in mind: The different versions of MSVC are incompatible. If the Qt DLLs are built with MSVC 2010, then you cannot use those DLLs with MSVC 2012.
Since the user wants to use MSVC 2010, he will need to download the binaries built with MSVC 2010.But if you've got just c++ code, then you maybe can compile it with a newer MSVC without problems.

Yes, the code is C++. My problem from the beginning was that I couldn’t run using MSVC.
Here is the “Kits”:Kits
Here is “Debug” options:DebugWhen I click on MSVC2013, it gives the same compiler error.
I think because my installed MVS is 2010, and this Qt works with MVS 2013. But just I wanted to be sure that it is possible to work with MinGW as a compiler for my GUI of C++ code or I need to install MVS2013? -
Okay, run the MaintenanceTool and select the MSVC2010 packages. Install them and afterwards try again. WIth that you should be able to compile with MSVC2010. Otherwise you might try installing MSVC2013 from the windows site and compile it with MSVC2013. I - personally - don't like MinGW, but you could try compiling your algorithm-code with MinGW, i can't tell if it will work since i don't know the code.

Thanks.
I selected the MSVC2010 32-bit OpenGL from the list in Maintenance toll, then in Projects I selected "Desktop Qt 5.4.2 MSVC2010 OpenGL 32bit" in "Add Kit" list, run and build it, and ran the program and it worked. Build & Run
I hope it works later with my code also, but does it matter my computer is 64 bit?
