Error message

Solution

See ​http://qt-project.org/doc/qt-5/deployment-plugins.html for more information about development of Qt plugins. You can set QT_DEBUG_PLUGINS environment variable to a non-zero value to see more information from plugin loader.

1. Check if filename 'PluginName.dll' is correct in your XML file.
2. Check if the correct version (release/debug) is used, see plugins postfix attribute in the XML.
3. Check if this file exists in the same directory as the executable.
4. Check if this component CMakeLists.txt uses create_export and pacpus_plugin macros and that it adds generated files to the source file list, e.g.:

   create_export(EXPORT_HDR ${PROJECT_NAME})
   pacpus_plugin(PLUGIN_CPP PLUGIN_H ${PROJECT_NAME})
   
   set(SRCS
       ${PLUGIN_CPP}
       ...
   )
   

5. (Windows specific) Check if the .dll file exports any symbols (using e.g. DependencyWalker).
