If you run the shell script getSvnRev.sh in your checked-out copy, it should update - but that requires a Unix-style shell, so might be a problem if you're building on Windows.

As Jonathan elaborated in the previous post, your assumption was not
correct. There is a script getSvnRev.sh which updates src/SvnRev.h, but
it's not called automatically during the build process. This is because
shell scripts are not supported on all platforms (Windows). Besides,
calling this automatically would make packaging a lot more difficult,
seeing that for packaging you often export your svn working copy to a
static version for which any svn commands would fail. But if you create
a script "update" with the content "svn up && ./getSvnRev.sh && qmake &&
make" things should work smoothly for you.

@Jonathan: How about using keyword substitution ($Rev$, see
http://svnbook.red-bean.com/en/1.5/svn.advanced.props.special.keywords.html)?
Of course it doesn't give us just the number, but it should be supported
on all platforms that run svn.
