Project error cannot run compiler cl output

I am new to Qt and this is my first post.

I am using Qt 5.12 on two different computers … both on MSVC (MSVisual Stuido 2017 ) identical version on both the machines but at different locations

computer 1. standard location c:program files …. etc
Qt 5.12 is installed on e drive ……….that is a usb drive

computer 2. it is D: ….. etc
Qt is also installed on D:Qt directory

On computer 1, I have absolutely no problem.
QtCreator started in next minute and I could compile and run textedit project in 10 minutes.

On computer 2, I cannot use Qt creator at all
It did not set the kit itself like it did on computer 1
It told me to set up kits ……so I put the paths for cl.exe and cmake.exe (after reading on google and Qt forums)

Still when I try to compile, it throws following error:

This is what I read from General Messages tab :

Running Windows Runtime device detection.
No winrtrunner.exe found.
Project ERROR: Cannot run compiler ‘cl’. Output:

===================
Maybe you forgot to setup the environment?

Project ERROR: Cannot run compiler ‘cl’. Output:

Please help or point me to where I can get proper direction.
Thanks

Hi and welcome to devnet,

Did you install Visual Studio 2017 also on both machines ?

@SGaist Yes sir. I have installed Visual Studio 2017 on both these machines and am successfully able to use both of those to build and create other Windows executables and libraries.

Thanks

Do you want to create classic Windows programs or UWP apps? Looks like the Qt version here is for UWP, not sure that was your intention.

Regards

@mvelanka said in Qt Creator says «Project ERROR: Cannot run compiler ‘cl’. Output:»:

No winrtrunner.exe found

seems like you did not install the windows software development kit ? It’s needed for the debugger.
AFAIC that one comes seperately from Visual Studio

@aha_1980,
Qt Versions are shown as follows:

HTH
Thanks

@J.Hilk

I believe I have two kits installed see this

Hope, I am in the right direction.
Thanks

@SGaist ,

Here is the screen shot showing compilers

In that «Custom» is the one I created/added by entering the values for Compiler Path and Make Path

Thanks

@mvelanka

it doesn’t work like this. MSVC compilers must be autodetected to be useable. Do you have the vcvars*.bat in the VS folder?

@aha_1980 ,
Yes I do have them

How to use these batch files?
Please let me know
Thanks

@mvelanka QtCreator uns this batch file to setup the build environment. I’m not sure how it finds this file, but it seems your non-standard installation confuses it.

Any reason to not install MSVC on drive C? ( I guess Qt is fine on D, but for the compiler I’m unsure)

@aha_1980 ,

The reason why VS and kits is in non standard location is because it is used in that way for our other projects.
We have many projects on windows.
This is the first time I am trying Qt

@mvelanka ,
Hopefully I have found the issue and the fix.

Apparently, there is nothing wrong with Qt.
I looked in the source code for QtCreator on this page:
https://code.woboq.org/qt5/qt-creator/src/plugins/projectexplorer/msvctoolchain.cpp.html
(That may not be latest, however it gave me idea how QtCreator looks for the vcvars bat files.)
It looks in the registry.
For some strange reason, the path for VC was stored as
C:Program Files (x86)Microsoft Visual Studio2017Community
instead of
D:Program Files (x86)Microsoft Visual Studio2017Community
I do not know why!!

So I manually fixed it in the registry to
D:Program Files (x86)Microsoft Visual Studio2017Community
and restarted QtCreator, went to kits………it gave me all the possible combinations to choose VC compiler
I chose amd64_x86………..and everything is working okay
I have test built one example project (textedit) and it seems to be running well.

I will still keep watch on both Qt and our other projects is this registry setup change creates any other issues.

Thanks for your support and clues.

Hello!
I am facing this problem while trying to install qwt.
The command «qmake qwt.pro» gives me the aforementioned error.
I understood that it probably has to do with the environment, so I added to the environment variables the path to the qmake (C:QtQt5.9.15.9.1msvc2015_64bin) as well as the path to the vcvarsall.bat (C:Program Files (x86)Microsoft Visual Studio 14.0VC), but I still have this problem.

Any help?
Thanks a lot in advance!

I might be wrong, but it looks to me that you are using a pre-compiled Qt version for MSVC 2015 64 bit.
Based on the path you appear to have Visual Studio 2015 32 bit. Please verify, if those assumptions are correct.

You cannot freely mix 32 bit and 64 bit versions. This could be the problem in your setup.

Please ensure that compiler and pre-compiled Qt library version are for the same architecture. Either 32 or 64 bit.

Thank you very much for the reply!
Everything you wrote was correct. Indeed I have Qt for both MSVC 2015 64 bit and MSVC 2015 (32 bit). I finally succeeded to install qwt.
So, the steps I followed in order to install qwt-6.1.3 (in case someone faces the same problem) are:

1. extracted Qwt source zip file to: C:Qwt-6.1.3
2. ran as administrator «Qt 5.7 64-bit for Desktop (MSVC 2015)»
3. moved into: cd C:Program Files (x86)Microsoft Visual Studio 14.0VC
4. then executed: vcvarsall.bat amd64
5. then moved into Qwt folder: cd C:Qwt-6.1.3
6. ran: qmake qwt.pro
7. then ran: nmake
8. and finally ran: nmake install

Thanks again!
