Dear Philippe,
as you can see in the attached file, class Lastra (and its derivate) seems
not to have any uncompleted functions....
..
Furthermore I have noticed the following:
If I execute my macro match.C (the one that uses class Lastra) with CINT,
I get a new strange error, computing a ratio between powers:
I got a division by zero ( having as denominator "pow(a,2)") even
if I
#include <cmath>
in the Class that performs such a ratio
and having "a" DIFFERENT from zero!
FACTS:
1. I used the class Lastra and Track to build the compiled library
libLastra.so
libTrack.so
using a proper Makefile, derived from a Template.
This was SUCCESFUL, and I build TTrees with Lastra Objects with great
pleasure!!!!
2. Nonetheless, at the ROOT prompt, if I give the command
.L match.C++ it gives the following output:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
root [0] .L match.C++

3. the "power" error appeared recently after I inserted in both Lastra
and Track classes the
#if !defined(__CINT__) etc,,
statements
to make the compile do not interfer with CINT requirements.
So...
Could it be that this Lastra error is linked to the power Error?
I separately tested all the class with a normal standalone C++ code... and
they worg good!
I' m puzzled!
Thanks for your help
Tommaso
