Re: Remote debuggind with gdb 5.3

[Magdalena.Iovescu@mail.uh.edu]

How do I make sure of that? Just by building my own filesystem? 

I tried to copy the library files fom my host to the target file system, and the system crashes. When I try to bring it up again, I get this:

     VFS: Mounted root (nfs filesystem).
     Freeing init memory: 76K
     init: error while loading shared libraries: cannot open shared 
     object file: cannot load shared object file: No such file or directory
     Kernel panic: Attempted to kill init!

Regards,

Magdalena
