Hi,
I have a little demo (see the source at the end)
which (when interpreted) produces the output
root [2] .U Mydemo.c
root [3] .L Mydemo.c
root [4] mydemo()
1:(2 tokens) =116.45 17243
token #0 @2629978’
Error: C++ exception caught FILE:F:\root\tutorials\Mydemo.c LINE:25
(const int)19
*** Interpreter error recovered ***
Although I do not know why the exception occurs, this is another thread,
I accept it runs correctly. Now I try to compile it.
It displays a fatal include error (WHY?)
and misses an include file (Do I need it? Is it really missing?)
then runs the application (What app if it is not compiled?)
with the same result as in interpreted mode.
What is that I am missing?
Thanks
Janos
