installing gcc 2.91.66 without disturbing existing gcc 3.3.3
I have to do an assignment in real time linux. For this I need to install the 2.4.4 kernel and apply a real time patch to that. While I was compiling the kernel It was exiting with errors. In the read me file it is mention that that version of kernel need to be compiled using gcc 2.91.66.
For this I downloaded two files from the gnu.org site.
egcs-1.1.2.tar.bz2 and egcs-1.1.2.tar.gz. I want install this version of gcc, but at the same time I dont want to loose my existing gcc 3.3.3. One of my friends said that it is really possible to install both the versions of gcc with different names and make use of them.
What is the procedure for that? and also I have a doubt regarding the versions of gcc. Why is it that gcc not maintaining any downward compatability which is an essential feature of any software. I have gcc 3.3.3 ( which is an advanced version compared to 2.91.66 ) using I am not able to compile a program which can be compiled using gcc 2.91.66.
Thanks in Advance.
