Fedora gcc

1. Go to http://gcc.gnu.org/ and download the version you want.
2. tar zxf gcc-xxx.tar.gz  or   tar jzf gcc-xxx.tar.bz2  to uncompress and untar the gcc source code. (xxx is version number)
3. as root
mkdir -p /usr/local/gnu
cd gcc-xxx
./configure --prefix=/usr/local/gnu/gccxxx   #<=== xxx is version number. For 3.2.2, xxx=322
make
make install
ln -s /usr/local/gnu/gcc322/bin/gcc /usr/local/bin/gcc
ln -s /usr/local/gnu/gcc322/bin/gcc /usr/bin/gcc322

So you can use /usr/bin/gcc322 or /usr/local/bin/gcc, which are point to the same gcc (usr/local/gnu/gcc322/bin/gcc)

Question:

What are all these?
What do I need?

Gnu make will have to use the older version of gcc.
I don't know how to make the connection unless I link gcc to the older version of gcc.

I downloaded gcc-3.3.4.tar.gz
./configure
make
this is what happens
gcc-4.0.0-8 gives an error when compiling  gcc-3.3.4

Please do as my first post
./configure --prefix=/usr/local/gnu/gcc334  
Otherwise you will conflicg with your current gcc (4.0) version.

Sorry for not following the directions the first time.
I still get errors. Tried several versions of gcc.

Fedora Core 4 just came out. I didn't have FC4 on hand.
I suspect that old gcc may not work on the FC4.
Could you provide the output of
/usr/bin/gcc -v

[root@localhost /]# /usr/bin/gcc -v

I added the line

Preallocated_Stacks       : constant Boolean := False;

/opt/gcc-3.4.4/gcc/ada/system.ads

but I just get another error

Look what I just found

Some applications will NOT compile in GCC 4.0. You can install GCC 3.2
to allow compiling applications which do not yet support GCC 4.0. Make sure
to have the following RPM's installed. These are included with the CD's or
DVD or online. Running 'yum install' on these names will also work.

compat-gcc-32            (on CD-disk3)
compat-gcc-32-c++      (on CD-disk4)

To use either, run 'gcc32' or 'g++32'.
