Description of problem: When trying to compile proxmark3 (https://github.com/RfidResearchGroup/proxmark3) using the qt5-qtbase-devel library, I get the following error that kills the build: /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 ‘< >’ I opened a bug report with the developer, and they pointed me here indicating it was an issue with how qt5-qtbase-devel was interacting with the C++20 compiler. Version-Release number of selected component (if applicable): qt5-qtbase-devel-5.15.13-1.fc40.x86_64 How reproducible: It occurs every single time. Steps to Reproduce: 1. Download the git repo on Fedora 40 2. Install required dependencies 3. run make -j all 4. Build fails Actual results: Build fails Expected results: Build to succeed Additional info: If I follow the suggestion as given by the compiler and edit line 248 of /usr/include/qt5/QtCore/qfutureinterface.h, then the build succeeds with no issues. Naturally, I don't think editing a library file like this should be done as it could cause issues in other library uses on the system.
Updated qt5-qtbase package with fix for this issue is now heading to stable repositories. This issue can be closed.
