Unfortunately by default yum will not allow you to install
an older version of a package when a newer version is available.
Sorry, not valid for gcc + the compat gcc packages. You can easily
have two to five compilers installed on Fedora 11 at the same time.
You will know that from the previous answer to @ufmale :
And ufmale, have you still got Fedora 11 ?
yum install gcc-c++ compat-gcc-34-c++
.. will install versions 4.4.1 and 3.4.6 .
We are still waiting for you to answer,
if the gcc-3.4.6 worked for you. ? ? ? ?
For the other "compat", gcc-3.3.3 , gcc-4.1.3, etc. ,
you will have to download the packages from the links,
you already know.
'yum' can be used :
yum --nogpgcheck localinstall <package>
You may prefer 'rpm' chain install ..
rpm -Uvh <package> <package> <package> <package> <package>
