I attached a working version of that program using Smoke. It's written
so that you don't link directly to -lsmokeqt, but dlopen() it. Ideally,
that would be portable, but the init() function isn't declared as
extern "C". The portable way is to link with -lsmokeqt directly, but I
don't really like that. Oh well. If Richard can patch Smoke with a new
version of the init() function, that'd be nifty:

extern void init_qt_Smoke();
extern "C" init_libsmokeqt() { init_qt_Smoke(); }

Compile with:
g++ -g -o hello hello.c -lqt-mt

and make sure you have libsmokeqt installed where it can be found --
either in your default lib path, or by setting LD_LIBRARY_PATH

Cheers,
Ashley Winters
