Description
Development Environment: Ubuntu 18.04, Qt Creator 4.14.0, Qt Framework 5.15.2
Target Platform: QNX 7.0 armv8 (aarch64)
I am trying to develop an application for a QNX target with CMake 3.20 as my build system. Configuring the project for a Linux target works, but configuring the project for QNX fails as CMake parses the project, and produces the following error:
/home/vagrant/Qt/5.15.2/qnx7_armv8/lib/cmake/Qt5Multimedia/Qt5Multimedia_.cmake:4: error: _populate_Multimedia_plugin_properties Macro invoked with incorrect arguments for macro named: _populate_Multimedia_plugin_properties /home/vagrant/Qt/5.15.2/qnx7_armv8/lib/cmake/Qt5Multimedia/Qt5MultimediaConfig.cmake:228 (include) /home/vagrant/Qt/5.15.2/qnx7_armv8/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package) CMakeLists.txt:28 (find_package)
I did some digging in the CMake code and believe the following is required to fix this issue:
1) Add "PLUGIN_CLASS_NAME = QnxAudioPlugin" to Src/qtmultimedia/src/plugins/qnx-audio/audio.pro
2) Replace qnx7_armv8/lib/cmake/Qt5Multimedia/Qt5Multimedia_.cmake with a new file called Qt5Multimedia_QnxAudioPlugin.cmake. The file contents should be as follows:
add_library(Qt5::QnxAudioPlugin MODULE IMPORTED) _populate_Multimedia_plugin_properties(QnxAudioPlugin RELEASE "audio/libqtmedia_qnx_audio.so" FALSE) list(APPEND Qt5Multimedia_PLUGINS Qt5::QnxAudioPlugin) set_property(TARGET Qt5::Multimedia APPEND PROPERTY QT_ALL_PLUGINS_audio Qt5::QnxAudioPlugin) set_property(TARGET Qt5::QnxAudioPlugin PROPERTY QT_PLUGIN_TYPE "audio") set_property(TARGET Qt5::QnxAudioPlugin PROPERTY QT_PLUGIN_EXTENDS "") set_property(TARGET Qt5::QnxAudioPlugin PROPERTY QT_PLUGIN_CLASS_NAME "QnxAudioPlugin")
I have attached a copy of a sample project which reproduces the described behavior.
