Estoy intentando instalar GCC-4.8 en Ubuntu 21.10.
Primero, intenté instalar desde un repositorio, pero fallé probablemente porque la versión 4.8 es demasiado antigua:
>sudo apt-get install python-software-properties
>sudo add-apt-repository ppa:ubuntu-toolchain-r/test
>sudo apt-get update
>sudo apt-get install gcc-4.8
El resultado del último comando fue:
>sudo apt-get install gcc-4.8
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'gcc-4.8-hppa64' for regex 'gcc-4.8'
The following package was automatically installed and is no longer required:
libfwupdplugin1
Use 'sudo apt autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
En segundo lugar, intenté compilar a partir de fuentes. Ejecuté estos comandos:
>wget http://www.netgull.com/gcc/releases/gcc-4.8.0/gcc-4.8.0.tar.bz2
>tar xjf gcc-4.8.0.tar.bz2
>sudo apt-get install libgm
>cd gcc-4.8.0/
>./contrib/download_prerequisites
>./configure --prefix=/app/gcc/4.8.0
>make -j 8
Pero finalmente recibí este error:

Mi gcc es "gcc versión 10.3.0 (Ubuntu 10.3.0-11ubuntu1)". Supongo que el nuevo compilador GCC no puede construir uno tan antiguo.
Por favor avise.
================================================
HACER UN SEGUIMIENTO
Intenté seguir el consejo que se proporciona a continuación y lo volví a compilar en una carpeta diferente: el mismo resultado, un error, pero uno diferente.
Usé los siguientes comandos:
tar xjf gcc-4.8.0.tar.bz2
./gcc-4.8.0/contrib/download_prerequisites
mkdir build
cd build/
../gcc-4.8.0/configure --prefix=/usr/local/gcc-4.8.0
make -j 16
El resultado fue:

¿Cualquier otra sugerencia?
Mi intuición personal es que el problema está en GCC v. 10.3.1 que se está utilizando para compilar GCC v. 4.8.0. Es posible que el nuevo GCC no sea compatible con el código fuente anterior.
Por favor aconséjame
