Hello, I have an application which I am linking with static Qt and static
plugins (QSQLiteDriverPlugin, platform plugins):
Q_IMPORT_PLUGIN(QSQLiteDriverPlugin);
#if defined(Q_OS_OSX)
Q_IMPORT_PLUGIN(QCocoaIntegrationPlugin);
#elif defined(Q_OS_WIN)
Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin);
#elif defined(Q_OS_LINUX)
Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin);
#endif
On Windows and Mac, things are working fine. However, on Ubuntu 14.04 (using
gcc 4.8) it does not appear that dependencies of the static plugins are being
linked with my application. I am sending libxcb-static.a, libQt5Sql.a, etc to
the linker but it appears that the linker does not think symbols from these
libraries are used and they do not get linked in with my application. Then,
when I run my application, it attemps to load the plugin and immediately fails
due to unresolved symbols. I have tried defining QT_STATICPLUGIN but that does
not seem to have an effect.
Is there any way to force static plugin dependencies to be linked with my
application on Ubuntu with gcc?
Thanks a lot,
Dan
