Can not get 21.3 in window mode

[Karl Schmid]

Hi,

I downloaded and compiled and installed Emacs 21.3 under SuSE Linux 8.0. 
Everything went fine, except that starting emacs from the commandline 
results in the no window (-nw) mode by default. 

Compilation was done with x support on. However, I could not get further.
What do I need to do (or where can I look up what to do) to start emacs
in the X mode by default?

Thanks.
