[pocket-linux] Chapter 3. The dreaded libc.so.6

[Bart]

Hi,

Try on your root disk to copy the libc.so.6 file into /lib.  The line
	>   libc.so.6 => /lib/tls/libc.so.6 (0x42000000)
tells you that that application (in your case bash) needs libc.so.6 and that 
this file actually is placed in /lib/tls. But if you  move libc.so.6 to /lib 
directory the application will work.

And maybe that's  your problem. I remember that some paths like /lib, /bin, 
etc are by default included as part of the PATH variable. But probably not 
/lib/tls.

On the other side, you tried this, so I am not sure...

Another thing I remember is that you cannot always just copy the libraries 
from your build machine to your host machine.
So can you tell me the specs on which machine you build your code, and the 
specs of the one on which you test it.
I had the same problems building on a AMD 1GHZ and testing on a PI 100 Mhz.
The libraries on the MAD where compiled for i686 and not for an i386.
But I am not 100% sure if I got the an error message, or nothing at all.

Finally, use the images for the chapter and uncompress it to your HD. Replace 
the original bash with yours, make the rootdisk again, and try it.
