[vlc] How to debug VLC using gdb

[Teddy Yan]

I try many times to debug vlc but all failed. One day lost.(:<

vlc version:
0.8.5
gcc version:
4.1.1
my compile option:
./configure --enable-x11 --enable-xvideo --disable-gtk --enable-sdl --enable-ffmpeg --with-ffmpeg-mp3lame --enable-mad --enable-libdvbpsi --enable-a52 --enable-dts --enable-libmpeg2 --enable-dvdnav --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-faac --enable-mkv --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-livedotcom --with-livedotcom-tree=/usr/lib/live --enable-caca --enable-skins --enable-skins2 --disable-kde --disable-qt --enable-wxwidgets --enable-ncurses --enable-debug --with-ffmpeg-tree=/home/teddy_linux/streamedia/ffmpeg

compile env varible:
CFLAGS=-g or -ggdb or -g3
CXXFLAGS=-g or -ggdb or -g3

I also tried to use --enable-release and CFLAGS=-ggdb or CFLAGS=-g3 or CFLAGS=-g but all failed. I got two different results:
One: (with --enable-debug or set CFLAGS or set CXXFLAGS) vlc file size 13,019,266

The other: (with --enable-release without set CFLAGS and CXXFLAGS)

(gdb) list
1       utils.c: No such file or directory.
        in utils.c
(gdb) break vlc.c:200
No source file named vlc.c.

where is utils.c? Is there no vlc.c? 

Thanks
Teddy
