Code requires g++ 2.95.3, what should I do?

Hi,
Is there any service/website where I can compile and build my code
using the outdated g++ 2.95.3? Instead of hacking the code (which now
produces many errors), or removing the newer g++ and installing the old
one?
Or there are other solutions?
Thanks!

Build gcc-2.95.3 on your own machine or install it from sunfreeware.com or
Sun's Companion CD.

Assuming the errors are correctly produced, fix your code. Kludging
around it with an out-of-date compiler is just asking for trouble.

The solution Dave suggested is a good workaround, but you should fix
your code.

My solution sucks if the OP's program links to libraries compiled with a
modern c++ compiler. Fixing the code is indeed the correct solution.

I would probably leave the decision to fix the code or install the g+
2.95.3 on the author of this topic. Answering on the direct question, I
would not recommend you to install the build package from
sunfreeware.com, because it will go to the same /usr/local

The probably the easiest way is to compile the gcc 2.95.3 from source
code and install it whatever you want. I actually got the same issue
trying to learn Rich Teer's book on the box with GCC 3.3.something
installed. His "GCC requirement" is using GCC 2.95.2. So, in order to
avoid fighting with various compiler versions, I just installed the
second one from source. For gcc 2.95.3 it should be the same as for
2.95.2 (or at least I hope so - I changed all my .2 to .3 in the
step-by-step info below). So I have both installed on my SUN box.

1. Download the binary from
ftp://ftp.sunfreeware.com/pub/freew...c-2.95.3.tar.gz to the
directory called /export/home/gcc_2.95.3_src/

2. Extract the source from archive
gunzip gcc-2.95.3.tar.gz
tar -xvf gcc-2.95.3.tar

3. Create the directory /usr/local/gcc/gcc-2.95.3
mkdir /usr/local/gcc
mkdir /usr/local/gcc/2.95.3/

4. Go the /export/home/gcc_2.95.3_src/gcc-2.95.3 and do this
../configure --prefix=/usr/local/gcc/2.95.3/
make CC=gcc LANGUAGES=c
make bootstrap
make install

5. Make sure that you set the PATH to your new GCC and run
gcc -version

Well, that version of gcc isn't necessarily a requirement, it's just
the one I happened to test the examples with.

Thanks for buying my book, BTW!
