Hi there !

I do not underestand how to correctly set breakpoints with gdb for a c++ application.

The bits i am interested in are in calendar_backend.

For example, I would like to get a break poing whenever i reach CMulticalendar::importIcsFileData:

[sbox-FREMANTLE_X86: ~/dev/test-cal/test1] > run-standalone.sh gdb ./test

(gdb) set args ./sample.ical
(gdb) b CMulticalendar::importIcsFileData
the class CMulticalendar does not have any method named importIcsFileData
Hint: try 'CMulticalendar::importIcsFileData<TAB> or 'CMulticalendar::importIcsFileData<ESC-?>
(Note leading single quote.)

Any idea what i am doing wrong ?

ouch... i should have read the "note leading single quote" .
I have been puzzled by since since yesterday evening, and i just find it 10 seconds after i posted here....

Actually, i still have a problem, the leading single quote trick did not work for ICalConverter::importEventDateEnd

(gdb) b ICalConverter::importEventDateEnd
Can't find member of namespace, class, struct, or union named "ICalConverter::importEventDateEnd"
Hint: try 'ICalConverter::importEventDateEnd<TAB> or 'ICalConverter::importEventDateEnd<ESC-?>
(Note leading single quote.)
(gdb) b 'ICalConverter::importEventDateEnd

here, tabs show nothing.

any help is appreciated.

You forgot the leading quote?
So: b 'CalConverter::importEventDateEnd
and then press Tab (two tabs to show all matching functions).
Note that in c++, arguments are added to the functions, something like foo(int,char*). Also namespaces needs to be added, so for 'namespace Foo { foo(int, char*); }' you need to write in gdb 'Foo::foo(int,char*)'
