Ich versuche, GCC-4.8 auf Ubuntu 21.10 zu installieren.
Zuerst habe ich versucht, die Installation aus einem Repository durchzuführen, was aber wahrscheinlich daran scheiterte, dass die Version 4.8 zu alt ist:
>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
Die Ausgabe des letzten Befehls war:
>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.
Zweitens habe ich versucht, aus den Quellen zu kompilieren. Ich habe diese Befehle ausgeführt:
>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
Aber irgendwann bekam ich diesen Fehler:

Mein gcc ist „gcc Version 10.3.0 (Ubuntu 10.3.0-11ubuntu1)“. Ich vermute, dass der neue GCC-Compiler einen so alten nicht erstellen kann.
Bitte beraten.
=============================================
NACHVERFOLGEN
Ich habe versucht, einem der unten stehenden Ratschläge zu folgen und habe es in einem anderen Ordner erneut kompiliert – dieselbe Ausgabe, ein Fehler, aber ein anderer.
Ich habe die folgenden Befehle verwendet:
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
Die Ausgabe war:

Irgendwelche anderen Vorschläge?
Mein persönliches Bauchgefühl sagt mir, dass das Problem in GCC v. 10.3.1 liegt, das zum Kompilieren von GCC v. 4.8.0 verwendet wird. Der neue GCC ist möglicherweise nicht mit dem älteren Quellcode kompatibel.
Bitte um Rat
