I managed to set up a (semi-automatic)
procedure to make a custom myroot (CINT) that
can access our local class libraries at some low levels.
So far, the testing raises in two issues:
(1) in CINT,
I type
an_object.local_class_member_function(0, 30.94, 1000);
This function takes variable length of arguments.
CINT tells me that
Limitation: Variable argument is not supported for this platform
FILE:/var/tmp/faawBaqX5_cint LINE:1
Arithmetic Exception
and it then exits out of Cint.
(2) If I type
local_class_name obj = another_class_name["column_name"]
where another_class_name should have been an object name (bt).
Cint has a hard time in recovering from the error.
First, it reports
"Error: No symbol another_class_name["column_name"]"
(a) Then when I type in the correct statement,
it tells me "*** Break *** segmentation violation"
(b) I then check the existence of the object (bt)
by typing --- bt
It appears to report the right class name for this object.
However, going back to step (a)
still gives me Segmentation violation error.
And another try of (b) kicks me out of Cint
with the message:
Fatal in <operator delete>: unreasonable size (8692120)
----------------------------------------------------
General questions:
I am using CINT version 5.14.85 on Solaris.
Is 'functions with variable argument' supported on the newer version ???
Our local class libraries have their own error trapping procedures
and thus are not designed specifically for error recovery in an
interpreter environment.
Could you point me to the place where I can learn about how
Cint catches and process an error
and how we can design codes to be integrated in Cint with
more forgiving error recovery ??
Thanks,
HP
