how to install older version of gcc -3 or gcc-4 in ubuntu 20

I'm trying to install an older version of gcc-4 on my Ubuntu system

Make a build directory (mkdir gcc-build && cd gcc-build)
Download the source file: wget http://www.netgull.com/gcc/releases/gcc-4.8.0/gcc-4.8.0.tar.bz2 (adjust this command to use an appropriate mirror site.
Unzip the file (tar -xvjf <file name>)
Install some additional libraries (sudo apt-get install libgmp-dev libmpfr-dev libmpc-dev libc6-dev)
Compile the source: ./gcc-4.8.0/configure --prefix=/app/gcc/4.8.0
Run make (This will take some time to complete. Go make some coffee, or bake some cookies. ;-))
Install the code: sudo make install

and finally run the sudo make install got this error

    make[1]: Entering directory '/home/ubuntu/gcc-build'
/bin/bash ./gcc-4.8.0/mkinstalldirs /app/gcc/4.8.0 /app/gcc/4.8.0
/bin/bash: line 3: cd: ./fixincludes: No such file or directory
make[1]: *** [Makefile:3405: install-fixincludes] Error 1

how can I fix this issue

Solution

Hope you have updated package manager, in doubt you can run following commands (in the same order given, which should run without errors):

sudo apt-get update
sudo apt-get upgrade

Then you need to ensure build-essential installed:

sudo apt-get install build-essential

After that you can install required version of gcc (example: gcc-4):

sudo apt-get install gcc-4

Now the part of selecting specific version of gcc:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4 4
sudo update-alternatives --config gcc

By this way you can switch between multiple versions of gcc too. The second command in the last step will give you a menu like option to select among available(installed) gcc versions to be set.
