Build error: C++20 -Werror=template-id-cdtor in proxguiqt.cpp

[AstreaeLuna]

Describe the bug
Build failure caused by C++20 compiler change: template-id not allowed for constructor in C++20

To Reproduce
Steps to reproduce the behavior:

1. Download git repo on Fedora 40
2. Install all required dependancies
3. Run make -j all
4. Build fails due to

/usr/include/qt5/QtCore/qfutureinterface.h:284:37: error: template-id not allowed for constructor in C++20 [-Werror=template-id-cdtor]
  284 |     explicit QFutureInterface<void>(State initialState = NoState)
      |                                     ^~~~~
/usr/include/qt5/QtCore/qfutureinterface.h:284:37: note: remove the ‘< >’

Expected behavior
The build should succeed.

Desktop (please complete the following information):

• OS: Linux - Fedora 40

Additional context
The error is resolved and the build can successfully complete if the change suggested by the compiler is made and <void> is removed from Line 284 of /usr/include/qt5/QtCore/qfutureinterface.h

This leads me to believe this isn't a problem strictly with Proxmark3 but with the QT development library. But I'm posting here to be sure.

Full build log is as follows:

same error on Arch, try to checkout the latest release tag then compile as usual.

[iceman1001]

This sounds more of a QT5 change than anything that we do

Bumped into this issue as well.

On main the error is:

So there is a difference in wording (error vs. warning). Not sure were it is coming from. Arch recently updated its gcc13 package. Maybe this changed something. Or like @iceman1001 said, something with Qt.

[iceman1001]

funny thing, the .moc.cpp is created by QT... So its nothing we have control over more than it might be needed to regenerate on your systems?

[AstreaeLuna]

@iceman1001 I'll look into reporting this bug to the QT devs instead. Out of curiosity, is there a way to retarget the build to use QT6?

[iceman1001]

you will need to modify the Makefiles / Cmakefile to use QT6 instead.

[AstreaeLuna]

Should I close this issue since it's a Qt problem or leave it open?

[iceman1001]

keep it open until you got some more answers.

For now you can use the following patch in order to just make build working and suppress the error:

diff --git a/client/Makefile b/client/Makefile
index 1b7090f68..22bd772b4 100644

 PM3CXXFLAGS = $(CXXFLAGS)

[AstreaeLuna]

I sent a bug report to the QT5 devs, who confirmed that the bug had been patched and the latest update to the upstream repositories should now resolve the issue.

If someone needs to patch their own Qt5 install, the line to change is https://src.fedoraproject.org/rpms/qt5-qtbase/blob/664f24855f26ccaee2501b26a50108b054bf19e2/f/qtbase-qfutureinterface-fix-build-with-gcc14.patch

 class QFutureInterface<void> : public QFutureInterfaceBase
 {
 public:
-    explicit QFutureInterface<void>(State initialState = NoState)
+    explicit QFutureInterface(State initialState = NoState)
         : QFutureInterfaceBase(initialState)
     { }

E.g. on Debian : /usr/include/x86_64-linux-gnu/qt5/QtCore/qfutureinterface.h
