QMAKE_MSC_VER isn't set

After I changed my Qt Version from 5.5.1 to 5.12.0 I get following message while I try to build any project:

msvc-version.conf loaded but QMAKE_MSC_VER isn't set

I selected the Qt 5.12.0 MSVC2017 32bit Kit instead of the Qt 5.5.1 (msvc 2013) Kit.

Does anybody know the reason for this message and could explain me how I should fix it?

If your intended compiler isn't MSVC to begin with, but rather MinGW, be sure you have the correct project configuration selected! :)

In older Qt versions, like Qt 5.6, which is last version that allows v2.1 of LGPL license.

Such thing as QMAKE_MSC_VER does not exist.

Simply create it, like:

  • Open mkspecs/common/msvc-desktop.conf file (from to Qt-sources) in editor.
  • Find: 
    unset(MSC_VER)
  • Replace it with below and done: 
    QMAKE_MSC_VER = $$MSC_VER
unset(MSC_VER)

Open msvc-version.conf (in my case in C:\Qt\Qt5.12.8\5.12.8\msvc2017_64\mkspecs\common)

add

QMAKE_MSC_VER = 1929

at the beginning (for VS2019).

I ran into this error message after returning to a project I hadn't worked on in a year. I solved it by deleting the project's .pro.user file. (It seems to have been looking for a build kit I had gotten rid of at some point in the year.)

Try removing any .qmake.stash files in your projects. This fixed this same issue for me when building QT from source after previously building with a different target.
