problems to install gcc

[Kay Schröer]

Hi,

I've some problems to configure, build and install the gcc collection.
I downloaded the file gcc-4.3.0.tar.gz.
Then I started the console (bash) and decompressed the archive by typing:
  gzip -d gcc-4.3.0.tar.gz
  tar -xf gcc-4.3.0.tar
The source files are placed in the directory /usr/gcc-4.3.0, for example
  /usr/gcc-4.3.0/compile
  /usr/gcc-4.3.0/configure
  /usr/gcc-4.3.0/install-sh
  ...
Now I want to install the package to the directory /usr/gcc to use the 
compilers.
I already read the documentation but there are so many commands and options, 
so I don't know what I have to do step by step.
Can you give me the necessary commands and options to configure, build and 
install a standard version of gcc (with all libraries installed to compile 
standard C-applications) to my system?
I'm using SuSE Linux 10.1 on a "normal" desktop pc as root user.

Thanks for help!
Best regards,
