multiple gcc / g++ running on FC 6

[powah]

FC 6 is installed successfully.
I had done
su -c "yum install compat-libstdc++-33 compat-libstdc++-296"
su -c "yum install compat-gcc-34 compat-gcc-34-c++"
which added gcc / g++ 3.4 in addition to the existing gcc / g++ 4.1.1.

If I want to add gcc / g++ 2.96 to support old linux programs, what is the best way to do it?

[mwette]

I would say the best way to do this is to download the sources and build
from scratch. I believe the "configure" script accepts an argument to add
a prefix/suffix to commands so that gcc could be installed as something
like gcc296.

I found this rpm:

and it generated

Is this right?

Looks promising. What does "rpm -qlp compat-gcc-296..." give?

Do you mean
rpm -ivh compat-gcc-296...?

Why /usr/bin/gcc296 is missing?

you've only installed compatibility libraries, to actually set up older versions of the gcc compiler see
