Hi Rui,
With your change I now get a compile error:
/home/robert/OpenSceneGraph/examples/osgmultiplemovies/osgmultiplemovies.cpp:
In member function ‘void SlideShowEventHandler::loadSlide(int)’:
/home/robert/OpenSceneGraph/examples/osgmultiplemovies/osgmultiplemovies.cpp:531:46:
warning: comparison between signed and unsigned integer expressions
[-Wsign-compare]
/home/robert/OpenSceneGraph/examples/osgmultiplemovies/osgmultiplemovies.cpp:
In function ‘int main(int, char**)’:
/home/robert/OpenSceneGraph/examples/osgmultiplemovies/osgmultiplemovies.cpp:654:116:
error: no matching function for call to ‘minimum(unsigned int&,
std::vector<std::basic_string<char> >::size_type)’
/home/robert/OpenSceneGraph/examples/osgmultiplemovies/osgmultiplemovies.cpp:654:116:
note: candidate is:
/home/robert/OpenSceneGraph/include/osg/Math:161:10: note:
template<class T> T osg::minimum(T, T)
At a guess I'd assume that the compile error you are seeing is down to
the max_videos and files.size() returning different types, so I've
introduced a cast:

+ unsigned int num_files_per_row =

This is now checked into svn/trunk, could you let me know if this
fixes the build or not.
Thanks,
Robert.
