Frankly, just throw out the crap event-drul and current-event, and

instead use

event-start and event-stop instead of (car event-drul) and (cdr

event-drul).

current-event also is never set to anything except (car event-drul),

so you can

just replace it with event-start.



This whole file is a huge parade of bad code.


Done.

OK, will do.



Fixed using new variables.

how to build lilypond in debug mode?

[Frédéric Bron]

Hi,
I would like to run lilypond in gdb to understand what happens when using ties.
How can I build lilypond for that?
When I run configure --help, it says it is built with debug info by default:
--enable-debugging  compile with debugging info. Default: on
But when I run gdb, I get some strange errors (see below).
