Is it possible to compile an ancient GCC 4.1.2 compiler to Centos 7.2?

Hello to everybody!

This is probably very stupid project because I would like to have an ancient
GCC 4.1.2 compiler to work in a brand new Centos 7.2 with its default compilers.

There are reasons for this why I need this very old compiler however.

I get this error from the compiler:

Code:

updating cache ./config.cache
configure: creating ./config.status
config.status: creating Makefile
config.status: creating gccbug
config.status: creating mklibgcc
config.status: creating libada-mk
config.status: creating auto-host.h
config.status: executing default commands
Bootstrapping the compiler
make[1]: Entering directory `/home/*****666/tools/gcc412/build/src/gcc'
make[1]: *** No rule to make target `bootstrap'.  Stop.
make[1]: Leaving directory `/home/*****666/tools/gcc412/build/src/gcc'
make: *** [bootstrap] Error 2
[*****666@veijo src]$

If there is ever any sense in this attempt and you dear reader think that you could help in this
rather hopeless matter please do help me. Thank you in advance.

Should I fix the Makefile somehow? I have no single clue how to do it....

What instructions are you following? It looks like you left out a step. I remember 3 phases to building GCC were making the bootstrap, making the intermediate compiler, then remaking the compiler with the intermediate compiler.

Well yes the phases are:

1.

Code:

../src/configure --prefix=/opt/gcc412 --program-suffix=412 --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --disable-libunwind-exceptions --enable-__cxa_atexit

2.

Code:

make -j 2 bootstrap

3.

Code:

su root
   make install

4.

Code:

cd /usr/bin
         ln -s /opt/gcc412/bin/gcc412 .
         ln -s /opt/gcc412/bin/g++412 .

...in case everything goes smoothly. I hope this helps to find out my mistake.

gcc 4.1 should be in the cent repos

but most things should build with 4.3 or 4.8

what is the exact need for that specific version

please give me a link for centos 7. So far I have found gcc 4.1.2 only for Centos 5.
