I'm using a Mac, and it seems as though Macs no longer use gdb for debugging (?) Codelite can use the lldb debugger which Macs now use. I cannot see how to add a watch as I'm using lldb as the debugger.
I'm trying to view the contents of a 2 dimensional array. In my sample code I'm creating this array with pointers and 'new'. I'll also be creating arrays with malloc() in c style too.
I think Codelite will show me the contents of a 1-D array, and a 2-D array created like...
double array[5][10];
But if my array starts as
double **myarray
I'm not sure Codelite is showing me the entire contents of the matrix.
So, I have two concerns:
- how do I add a watch, using lldb, also - can I edit a watch in the debugger window?
- how do I view contents of a 2 D array that's created with 'new' or malloc()
I haven't tried this with malloc() yet, so I'll try to view a 2D array created with malloc()
Thanks for any help

Re: How to add a watch using lldb debugger, for 2D array vie
I am working on adding watch support for lldb as we speak
So its not possible just yet to do this.
But you will be my first beta tester

Re: How to add a watch using lldb debugger, for 2D array vie
For compiler (and debugger) knows the memory layout.
Forwe don't know the size. With gdb you may use to display element as array (you have to fix the size).
A possible hack would be to declare to have array_view in local variable.
Code: Select all
double array[5][10]
For
Code: Select all
double** array
Code: Select all
array[0][0]@10
A possible hack would be to declare
Code: Select all
double (*array_view)[10] = (double (*)[10])(array[0]);

Update:
I have added support for watches for the LLDB debugger.
So, you can basically use it to watch 2-D array allocated on the heap (using malloc) as Jarod42 suggested:
Click on the '+' button and add a watch with the following expression:
See attached screenshot

Re: How to add a watch using lldb debugger, for 2D array vie
Hi Eran,
I added the following:
in CL's LLDB's prefs to see std::string (on Linux with libc++ and libcxxrt) and it works fine except only the "Summary" column is populated - the "Value" stays empty. I didn't find a way to populate the value based on the summary, only the other way around. What would be the solution?
Alternatively, is there a way to get LLDB's command line to experiment with formats in real-time?
Btw the LLDB prefs' ok button stays disabled unless some value is changed.
thx & cheers,
