Building Qt 6.1.2 under windows says perl is missing when in fact it isn't
Solved
Installation and Deployment
-
I am trying to build Qt 6.1.2 from sources under windows, using visual studio 2019, but I can't get it to work at all for some reason.
This is the setup I am using to run configure:
As you can see cmake, ninja, python, perl and licheck (the one from qt sources in qtbase/bin) are all available to the shell. After several seconds, configure script fails with a rather cryptic message:
CMake Error at qtbase/cmake/QtSyncQtHelpers.cmake:7 (message): Perl needs to be available to build Qt.

Hi,
Where does that version of Perl come from ?
One possible way to get you through is to define HOST_PERL with the path to your Perl executable.
-
Hey and thank you for the quick response!
The perl version I have installed is a strawberry perl for windows. I tried your HOST_PERL suggestion but the message was exactly the same.
Is it possible the straberry perl to be unsupported for some reason? I tried getting ActiveState perl, but the whole download process there is complete and utter mistery - forking some projects, downloading something called state, which ... activates(??) .. something. I still can't figure out how the hell is one supposed to just get a perl installation. Or is it even possible.
-
AFAIR, you have the correct variant...
I just realized, if you want to build that version precisely, you could do it from the source archive directly which should be easier than from git.
-
After struggling for a while I found the problem. It turns out strawberry perl needs its own ~/c/bin directory to be in the PATH as well. It is fairly weird since this directory contains all kinds of stuff - gcc, g++, ar, iconv and a lot more so I really didn't want those to pollute my PATH. perl.exe itself seems to be working fine without it, but obviously there are some cases where it doesn't.
Using active perl (older version - 5.28, newer ones are not available for direct download it seems) is an option too, and it doesn't pollute the PATH with all that.
-
Glad you found out and thanks for sharing !
