I have wrapped my C/C++ code using SWIG in Perl. I have few segmentation fault because of the wrapped code. I am trying to use ddd
with the Perl script but unfortunately even if I set a breakpoint on a line of the script ( the one calling C/C++ code ), ddd
is not able to step in down to the C/C++ code.
Is there any way to set breakpoint into my C lib when I am debugging Perl code or do you know a good way/tool to debug the C lib when I am running this Perl script?
I am using Linux/gcc.
I did a simple thing. I called the gdb
directly on perl
interpreter.
gdb /usr/bin/perl
(gdb) r myscript
#block the script someway or rerun it
(gdb) b whatever_my_function
It seems that once the scipt is running shared memory is also loaded in memory. Once this happened I have available all information, functions and breakpoint for debugging.
