I feel I'm missing something obvious here, but I just can't see it. I have a cmd window open, and here's what I run:

set QTDIR32=C:\Qt\5.10.1\msvc2015
%QTDIR32%\bin\qmake.exe -v

C:\Qt\5.10.1\msvc2015\bin\qmake.exe is a valid path to an executable tool.
Expected: the tool's output.
Observed:

'C:\Qt\5.10.1\msvc2015' is not recognized as an internal or external command, operable program or batch file.

Tried various combinations of quotes around different parts of the command; tried start %QTDIR32%\bin\qmake.exe -v - it opens the 'C:\Qt\5.10.1\msvc2015' folder in Explorer.

echo %QTDIR32% prints the expected output.

What am I missing?

  • @Mofi: fair enough, but as I said in the question, it was never a batch file. I opened cmd.exe and typed these commands by hand. Then copied them and posted here. Commented Apr 19, 2018 at 14:25

Always use double quotes on paths.

set "QTDIR32=C:\Qt\5.10.1\msvc2015"
"%QTDIR32%\bin\qmake.exe" -v

The reason for double quotes are not always because of spaces between paths, but gets rid of any unwanted whitespace in the actual batch. double quotes are always a good idea.

Hmm. This shouldn't be necessary here because the path has no spaces, and it shouldn't ever be necessary for the set command according to ss64.com/nt/set.html. Let me try your suggestion.
That did it, thank you (the quoted call to set). I'm starting to think I've had a stray space in the end of my path when calling set.
Yes, hence the quotes :)
I see your wisdom now :)
