Hi, The feature is marked in configure.cmake as PRIVATE only.
Try explicitly including one or both of #include <QtCore/private/qconfig_p.h> #include <QtCore/private/qtcore-config_p.h> Note that in src/corelib/ipc/qsystemsemaphore_p.h there is #if QT_CONFIG(systemsemaphore) #include "qcoreapplication.h" #include "qtipccommon_p.h" #include "private/qtcore-config_p.h" and FEATURE_systemsemaphore will be disabled on integrity due to its condition in configure.cmake as shown below. CONDITION ( NOT INTEGRITY AND NOT VXWORKS AND NOT rtems ) AND ( ANDROID OR WIN32 OR TEST_sysv_shm OR TEST_posix_shm ) ________________________________________ From: Development <development-boun...@qt-project.org> on behalf of Thiago Macieira <thiago.macie...@intel.com> Sent: Saturday, November 5, 2022 6:18 PM To: development@qt-project.org Subject: Re: [Development] C++20 structural types (was: C++20 @ Qt) On Saturday, 5 November 2022 10:08:55 PDT Allan Sandfeld Jensen wrote: > Sure.

I am going to reserve the metatypes for them, though. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
