Re: problem with gdbserver on powerpc

Thanks Daniel,
 
I was able to debug my program to some extent but got struck as I can not fully use the debugger.  Please take look at the issues
 
Issue:1 can't make use of back-trace past-main on 
I do get 2 different errors on different times of execution. 
---------------------------------------------------------------------------------------------------------
This GDB was configured as "--host=i686-pc-linux-gnu --target=powerpc-linux"...
(gdb) set backtrace past-main on
No symbol "backtrace" in current context.
(gdb) set solib-absolute-prefix /usr/local/powerpc-mozilla/lib/firefox-1.5.0.3
(gdb) set solib-search-path /usr/local/powerpc-mozilla/lib/firefox-1.5.0.3
(gdb) target remote **.***.**.**:2345
Remote debugging using **.***.**.**:2345
0x30012054 in ?? ()
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
(gdb)
 
 
Issue 2: After running the program for sometime and check for bt
(gdb) bt full 
#0  0x30008e5c in ?? ()
No symbol table info available.
(gdb)
However, I do get backtrace full working at later point of time while the thread goes into do while loop  forever. 

(gdb) set backtrace past-main on
A parse error in expression, near `past-main on'.

 
Please do let me know where I am mistaking.
 
regards,
Ravi

It sounds like you don't have GDB pointing at the shared libraries for
your target system, so you can't see where you're stopped.  Try "set
solib-absolute-prefix".
