[Qt-interest] runtime compilation impossible in Qt???

[John Cummings]

I believe that you are thinking of CINT:

>From the webpage: "CINT is an interpreter for C and C++ code. It is useful 
e.g. for situations where rapid development is more important than execution 
time."

I haven't used it myself, but have thought about it.

Been done... There is a library out there.. used it a while back.. that
reads in a c++ file compiles it into a DLL/.so and allows you to run a
function from it..  Worked pretty well with the g++ flow...

Been years.. but yes, interpreters do allow dynamic functionality like
that to be easier...

Try executing dynamically created C++-code :-) Something like 'eval(
"print \"bla %s\"" % some_string_variable )' is not possible in C++ at
least to my knowledge. At least not as easily as in python. 
One can compile the dynamic code into a library/plugin and dl-open that
but unloading and loading the new version gets harder and harder...
