There are 3 different steps you have to follow for that which are:-
./install [-d"dir"] [cpu_family1] [cpu_family2] ...
Here if we want to install ELDK than suppose our directories are as:-
"/opt/eldk4.2" than 3 steps to be followed are:-
1 ./install -d /opt/eldk4.2 ppc_6xx
2 ./ELDK_MAKEDEV -d /opt/eldk4.2 ppc_6xx
3 ./ELDK_FIXOWNER -d /opt/eldk4.2 -a ppc_6xx
-------------------------------------------------------------->
-a
At last you are complete with the installation and can start doing you work.
