Compile error in kcoreaddons

Help
1

Hello,

I just wanted to do some coding in a KDE application. Therefore I started to set up my development environment using kde-builder.
I followed the instructions defined on the /kde-builder web page.
While compilation of kcoreaddons I get a build aboard.
The error message is:
/usr/include/qt6/QtCore/qglobal.h:13:12: fatal: ‘type_traits’ file not found
When I search for this header file I get these results:
/usr/i686-w64-mingw32/sys-root/mingw/include/c++/type_traits
/usr/i686-w64-mingw32/sys-root/mingw/include/c++/bits/cpp_type_traits.h

Could somebody give advice how to proceed?

A temporary solution is to not fulfill the dependency to Shiboken6.
These are the packages that I do not consider:
shiboken6-0:6.8.0-2.fc41.x86_64
python3-pyside6-0:6.8.0-2.fc41.x86_64
python3-shiboken6-0:6.8.0-2.fc41.x86_64
python3-pyside6-devel-0:6.8.0-2.fc41.x86_64
python3-shibokepyside6-tools-0:6.8.0-2.fc41.x86_64
pyside6-tools-0:6.8.0-2.fc41.x86_64

have you installed the shiboken6 package?

Hi - I’m getting a similar error, and have all the shiboken6-related packages installed on Fedora KDE 42:

$ dnf list --installed | grep shiboken
python3-shiboken6.x86_64                             6.9.0-1.fc42                            updates
python3-shiboken6-devel.x86_64                       6.9.0-1.fc42                            updates
shiboken6.x86_64                                     6.9.0-1.fc42                            updates

But I get this in the logs:

The most relevant-seeming thing I could find was this Qt bug report, but that says it was fixed in Qt 6.7. If anyone has any ideas, that would be awesome :slight_smile:

Hello @johnandmegh

I’d been struggling with the exact same issue for a week!
kde-builder works as expected on VM on a fresh F42, however not in a host.

In my case I was able to make it work installing clang.

Although, this error disappeared, the next one was introduced.
I can’t find logs, but the issue solved by installing a build package for pip3.

I feel like there is something with the path to gcc, though I can’t make it work using env’s or submitting parameters e.g. DCMAKE_CXX_COMPILER:FILEPATH=%{Compiler:Executable:Cxx}

Thank you for bringing this back up! I totally forgot to follow-up here, but I did get some advice in the Matrix chat rooms on this one that included clang, just like you mentioned, and also python3-build - with those, everything in workspace built (except for krdp, but I expected that given the FreeRDP 2 vs 3 difference).

There’s a merge request in the repository where those distribution dependencies are managed, currently being reviewed to figure out how to solve appropriately: https://invent.kde.org/sysadmin/repo-metadata/-/merge_requests/565

Thanks!
