OK you have 2 or 3 different approaches here
a) download the source and create your program with the *NIX trinity (./configure; make; make install)
b) download a binary rpm and install it using yast
b) is clearly the easier approach, as you download it and if I remember correctly ind KDE just double click it and SuSe should asked you if you want to install it on which it starts yast
a) takes some "fiddling" sometimes.
In your best case senario it should work like this
Code:
./configure [note it is dot slash]
make
su -
make install
if it doesn't got so nicely if you need to hand some parameters to configure
taking apache as example what modules you want and such things
often you can tell configure where you want to have the program to using the prefix cmd
advisable would be to read
I) the output of ./configure --help
II) the files README and INSTALL that come with the src
I hope it helps you
