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?
The most straight-forward way of debugging an X server is to build it with
...
#define DoLoadableServer NO
... in your xc/config/cf/host.def. After a `make World`, this'll build
everything into one binary.
