Ubuntu 21.10에 GCC-4.8을 설치하려고 합니다.
먼저 저장소에서 설치를 시도했지만 버전 4.8이 너무 오래되었기 때문에 실패했습니다.
>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
마지막 명령의 출력은 다음과 같습니다.
>sudo apt-get install gcc-4.8
Reading package lists... Done
Building dependency tree... 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.
둘째, 소스로부터 컴파일을 시도했습니다. 다음 명령을 실행했습니다.
>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
하지만 결국 다음과 같은 오류가 발생했습니다.

내 gcc는 "gcc 버전 10.3.0(Ubuntu 10.3.0-11ubuntu1)"입니다. 나는 새로운 GCC 컴파일러가 그런 오래된 것을 만들 수 없다고 추측합니다.
조언해주세요.
=============================================
후속 조치
나는 아래에 주어진 조언을 따르려고 노력했고 다른 폴더에서 다시 컴파일했습니다. 동일한 출력, 오류, 그러나 다른 폴더입니다.
다음 명령을 사용했습니다.
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
출력은 다음과 같습니다.

다른 제안이 있나요?
내 개인적인 직감은 문제가 GCC v. 4.8.0을 컴파일하는 데 사용되는 GCC v. 10.3.1에 있다는 것입니다. 새로운 GCC는 이전 소스 코드와 호환되지 않을 수 있습니다.
조언 부탁드립니다
