Hi, I've been working on a patch to make it easier to use CMake with a statically built Qt 5:
https://codereview.qt-project.org/#change,56215 A complexity arises in that all Qt 5 applications must load a platform plugin. If Qt is built statically, the platform plugin must be loaded by using the Q_IMPORT_PLUGIN macro. Rather than forcing all Qt-using code to have a shared/static specific snippet, qmake generates a small file like this: #include <QtPlugin> Q_IMPORT_PLUGIN(QXcbIntegrationPlugin) // Or Win plugin on Windows. and compiles it into the executable. In my patch above I tried a similar approach by creating a static library with the above snippet and adding it to the link interface of Qt5::Gui. However, the plugin import code does not get executed at runtime. I assume the linker ignores the code because the executable doesn't use any symbols from it. The solution would be to generate an OBJECT library instead of a static library. However, it is not possible to link to an OBJECT library currently. I was wondering why that is, and if it can be changed? Alternatively, can you think of any other solutions for this? I don't want to require people to have to use something like: add_executable(myexe ${Qt5StaticObjectPluginLoader} main.cpp) Thanks, Steve. -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
