Thank you for the reply. I have some more doubts
regarding this, please excuse me for asking these
basic doubts.

1) If configure script need not be modified, why
should we pass 'host=name' parameter to configure?
where is this parameter used?

2) How I know the name of 'host=' parameter for my
target?

3) How we tell configure the location of other
cross-compiled library files?

4) How we tell configure the location of other host
specific include files?

I have /opt/kenati/lx4189-kenati-linux folder with bin
include and lib subfolders. The 'bin' folder has cross
compiler tools (lx4189-uclibc-gcc etc), 'include' has
target specific include files and 'lib' has
cross-compiled libraries.

5) How can I tell 'configure' to look for include
files and library files in the above folders instead
of default folders?

PLEASE HELP.

thanks 
shamju joseph
