Re: problem with gdbserver on powerpc

[ravi kiran <rkmovva at yahoo dot com>]

The version is  6.4. 
I did cross-compile gdbserver with with gcc3.4.1 and glibc-2.3.3(crosstool generated tool kit)
 
I am using the thread_db and libpthread solibs generated by the tool.  Still I get the 
gdb: error initializing thread_db library: version mismatch between libthread_db and libpthread.
 
Do we need to keep the same libraries in the host machine also??
 
Regards,
Ravi

You didn't say what GDB version you are using.  Apparently, it is too
old.

That's unlikely to be right.  solib-search-path should be a directory
containing libraries (if you need to use it at all, which you rarely
do).  solib-absolute-prefix should be a filesystem image, so a
directory containing "lib" and "usr".

This is probably related to the solib-absolute-prefix problem.
