Compiling the binding (c++ code) in scratchbox is fine.

I hope you do not do this in scratchbox, scratchbox tries to 
foul the compilers, it does not work with fpc.

Strange, that function is inline, can you provide me the definition of it in
the qt headers. In Desktop Qt 4.5 and 4.7 it is:

from header qt-all-opensource-src-4.5.3/src/gui/text/qtextobject.h:

class Q_GUI_EXPORT QTextBlock
{
...snip...
    inline bool isValid() const { return p != 0 && n != 0; }

Therefore I do not expect this symbol to be present in any Qt lib.

Can you also detail your setup (I am curious)
I see meego but also harmattan, I have no harmattan experience, 
but I suppose it is like fremantle and therefore not binary compatible 
with hardfloat meego ?!
