Bug ID: 481419
Summary: Failure to build kcalc right after successfull
kdesrc-build --pretend
Classification: Developer tools
Product: kdesrc-build
Version: Git
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: mp...@kde.org
Reporter: listes.rusc...@laposte.net
Target Milestone: ---
Greetings,
>From the git https://invent.kde.org/sdk/kdesrc-build page, I followed all the
steps up to:
$ kdesrc-build --pretend
The output is very reassuring:

I thus go on with the build of kcalc (small program to start with) and at that
point that fails like this:
```
% kdesrc-build kcalc

Possible solution: Install the build dependencies for the modules:
kconfig
You can use 'sudo apt build-dep <source_package>', 'sudo dnf builddep
<package>', 'sudo zypper --plus-content repo-source source-install
--build-deps-only <source_package>' or a similar command for your distro of
choice.
See https://community.kde.org/Get_Involved/development/Install_the_dependencies
Important notification for kconfig:
kconfig has failed to build 7 times.

```
At that point, I look into

```
And looking into ECMQmlModule6.cmake, line 24 :
```
23 # Stop warning about a changed import prefix.
24 qt6_policy(SET QTP0001 NEW)
```
Two questions:
1. It seems line 24 is not essential, how can I comment it out and rerun the
build without having my modification overwritten ?
2. Where is the qt6_policy macro defined ? Am I missing some Qt6-related
package ?
Thank you for your work and for your help,
Sincerely,
Filippo
