How to enable debugging?
The best way of providing some more detailed information is:
Turn off optimization, and turn on debugging symbols in the
spectro/Jamfile, ie:
Change this
CCFLAGS += $(CCOPTFLAG) ; # Turn optimisation on
#CCFLAGS += $(CCDEBUGFLAG) ; # Debugging flags
to this
#CCFLAGS += $(CCOPTFLAG) ; # Turn optimisation on
CCFLAGS += $(CCDEBUGFLAG) ; # Debugging flags
Change spectro/dispwin.c line 55 from this
#undef DEBUG
to this:
#define DEBUG
and recompile the spectro directory - ie;
rm *.o
jam
Run dispwin using the debugger, and get a backtrace at the
point it fails - ie:
gdb dispwin
(gdb) run
on crash:
(gdb) bt
to quit:
(gdb) quit
And relay the debug messages and the backtrace.
thanks,
Graeme Gill.
