long reply  :(


I did not read this anywhere yet.  It seemed to be spelled out 
pretty well on the installing GCC configuration page as simply;

configure
make
make install.

I'll try this.  I'm just trying to do this so I don't
wipe out the older compiler on the COL 3.1.1.  It comes with
2.95.2.  Hopefully, the old directory is still there, since
I have a fast cron job that wipes that area fairly regularly.

2.95.3 permits to experiment with the newer types of kernels, which
I am going to try soon.

>From the pages from the GNU site, I read over the configuration
material, and performed the install this way;

Download gcc-2.95.3-everything.tar.gz from primary site;
Copied the file to /usr/src directory;

]# gzip -cd gcc-2.95.3-everything.tar.gz | tar -xvf -

]# chown -R username:users /usr/src/gcc-2.95.3

]# cd /tmp

]# mkdir gcc-obj

]# cd /tmp/gcc-obj

]# ../gcc-2.95.3/configure --prefix=/usr/local/gcc-2.95.3 
       --includedir=/usr/local/gcc-2.95.3/include
       --libdir=/usr/local/gcc-2.95.3/lib
       --with-gxx-include-dir=/usr/local/gcc-2.95.3/include/g++
       --enable-version-specific-runtime-libs
       --with-included-gettext
       --with-gnu-as=/usr/i386-linux/bin
       --with-gnu-ld=/usr/i386-linux/bin
       --enable-threads=posix
       --enable-shared

]# make
]# make install

After this, I changed 2 files;

I editted the /etc/config.d/shells/bashrc  
file, and altered the statement for the enviroment from
/usr/local/bin, to /usr/local/gcc-2.95.3/bin.

I also altered the /etc/ld.so.conf file, and 
added the following libraries created by my compiler
addtion, from above...

/usr/local/gcc-2.95.3/lib
/usr/local/gcc-2.95.3/lib/gcc-i686/  etc.,

Since I did not know the command to re-read the ld.so.  cache, 
since if I logged out, the profile would automatically change
when I logged back in.  So I rebooted.

>From the command prompt, I get

]# gcc --version

2.95.3

Seemed pretty straight forward to me, after attempting to understand
all the options available for the configuration of the compiler.

The reason for all this is to create a compiler, without destroying
the old one.  I have a labtop that has COL 2.4, with limited
memory and drive space, and I want to compile 2.2.x kernels on this
computer, and then tranfer them to the labtop.

[ both are Pentium 2 processors ].

The newer compiler is slightly faster ( 450 Mhz ), and has more
ram ( 512 M ).  I though the speed and memory would speed it
up a bit, since the other computer has only 64M.
