newbie trying to install and build

[chris kuhlman]

Hello:

I downloaded gcc-4.3.0 from the gnu site and am trying to install and 
build it on a linux cluster with i86 processors.

I tried to find prebuilt binaries but was able to.

So, I am trying to build it from the source.  I have read through the 
online documentation, but am hoping that default settings will be OK, 
because there was a lot I did not understand.  gcc versions 3.3.5, 
3.4.3; 4.0.1-4.0.3, up to 4.1.0 are already on the machine, so I figured 
that I could build from one of those.

However, I look in the gcc-4.3.0 directory and I type "make" and I get:
make: *** No targets specified and no makefile found.  Stop.

There is a configure script and I ran that.  However, in general, I am 
looking for instructions on how to proceed.  I could not find explicit 
instruction for doing the build within gcc and the URL:
http://gcc.gnu.org/install/

What am I doing wrong?

I am most grateful.
