Dear All: I want to trace the
behaviors of my video driver under Xfree86 and have done the following
steps which were collected from this mailing list. 1. prepare two machines;
one is called host, and another is called target. 2. type "makeg
World" under "xc" folder 3. telnet the target from
host and run "gdb /usr/X11R6/bin/XFree86" 4. under the gdb command
mode type "run :0" Here my question comes
from. I type "list" under gdb command mode. I saw the source code of
XFree86, main.c, but if I set the breakpoint about the driver functions
such as Probe, ScreenInit and EnterVT, which are assigned to pScrn. The gdb
told me that he cannot find the symbol file. Are there some steps
between 1-4 I made wrong or in fact I didn't build the symbol file correctly? By the way, while manning
gdb, I saw another way to build remote-debug by using gdbserver. Below are the steps
excerpted from the document: (here I use com1 for
example) 1. target: #gdbserver
/dev/ttyS0 exe-command argument 2. host : #gdb 3. host : #gdb>
target remote /dev/ttyS0 Both sides are waiting for
awhile, and then it say "Ignoring packet error, continuing..." ps:I have check the com1
port is well-functional. Any suggestion will be
appreciated. Thanks a lot |
