Re: [parisc-linux] Initial setup of the `glibc' in the target rootfile system

[Christoph Plattner <christoph.plattner@alcatel.at>]

First of all, the make install has to be done twice !

One time for the tool chain to find the things like crt?.o, libs, etc..
For this the builtin tree is defined (given by --prefix).

	make install user-defined-trusted-dirs=/lib

The second time install it to the nfs root file system

	make install user-defined-trusted-dirs=/lib \
	  install_root=/tftpboot/nfsroot

For the target the `/lib' is the builtin search path, for the
cross tool chain the '/usr/parisc/hppa-linux/lib' (in my case).

AND A VERY IMPORTANT POINT: You have to run `ldconfig'. I tried
this on the target machine (apollo 720) by booting from the
NFS-ROOT of palinux-0.5 (I copied the contents of the CD to a
path exported by NFS). After booting I mounted my new NFSROOT to
`/mnt' and run 
	ldconfig -v -r /mnt

After that I could boot from the new root file system starting the
`init' process (but nothing else....)

Another test to do is to use host's ldconfig fore that work:

	ldconfig -v -r /tftpboot/apollo/root

or something like this...

Cheers
