Wondering if anyone has encountered this problem where gdb/gcc doesn't
seem to be getting the line number info right.
I compiled code in as
----------------------------------------------------------------------
gcc45 -g -W -Wall -O0 -std=c99 -D_BSD_SOURCE -DDEBUG -D__BSD_VISIBLE
-DFREEBSD -c interreflect3d.c
-o x86-debug/objects/interreflections/interreflect3d.o
gcc45 -g -W -Wall -O0 -std=c99 -D_BSD_SOURCE -DDEBUG -D__BSD_VISIBLE
-DFREEBSD interreflect_driver.c
x86-debug/objects/interreflections/interreflect3d.o
-o x86-debug/bin/interreflect_driver
-I./
-Ix86-debug/include
-Ix86-debug/../external/include
-Lx86-debug/../external/lib
-llapack -lf77blas -lcblas -latlas -lgfortran
----------------------------------------------------------------------
and then I go to debug. I seem to stop in my function ok, locals and
such seem ok, gdb seems to handle OK, except the line number
information is wrong:
#0 0x000000000040467b in reconstruction_prune (r=0x7fffffffe420,
intensity_threshold_min=1,
intensity_threshold_max=999999, jump_discontinuity_threshold=100,
clustersize=5)
at interreflect3d.c:296
#1 0x00000000004013ef in main (argc=26, argv=0x7fffffffe620) at
interreflect_driver.c:103
For #0, the correct line is 1108, not 296. #1 is correct.
This incorrect line number info is giving me grief while I'm trying to
step through my code.
Anyone have a hunch what's going on here?
Thanks.
