Ich versuche, Pymedia in Ubuntu zu installieren, um Skripte mit Python 2.7 auszuführen. Also habe ich die Abhängigkeiten aufgespürt und sie installiert:
sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad2-dev libasound2-dev python-pygame libmp3lame-dev libevent-dev
Als ich mit der Installation des oben genannten fertig war, erhielt ich beim nächsten Schritt, dem Erstellen von Pymedia, Folgendes:
Using UNIX configuration...

Wie aus den Ausdrucken ersichtlich ist, werden die Pakete (trotz ordnungsgemäßer Installation) als „nicht gefunden“ angezeigt. Und die unterste Fehlerzeile sieht für mich nach einem GCC-Fehler aus. Es wäre wirklich hilfreich, wenn jemand darauf hinweisen könnte, was hier schief laufen könnte.
Antwort1
Viele, viele Leute haben dieses Problem. Es liegt höchstwahrscheinlich an einem fehlerhaften Skript.
Offensichtlich müssen 64-Bit-Shared-Bibliotheken mit dem Flag kompiliert werden, -fPICund in diesem Fall ist dies bei sound.cpp nicht der Fall.
Darin setup.pygibt es eine Funktion namens disable_fPIC()– Sie können die Funktion deaktivieren, indem Sie einfach den gesamten zugehörigen Code durch die Anweisung ersetzen pass.Also:
def disable_fPIC():
pass
