PyQt4 su Snow Leopard a 64 bit

Question

Ho appena compilato l'ultima anteprima di Qt4.6 su Snow Leopard a 64 bit senza problemi importanti.

http: // qt .nokia.com / developer / QT-4.6-tecnologia-preview # download-the-qt-4-1

Ora sto provando a fare lo stesso per PyQt4.6 con l'ultima istantanea dal sito web di River Bank. Tuttavia, il compilatore esce con il seguente problema:

È un errore con PyQt4 che tenta di accedere a un membro privato di una classe Qt4? Qualcuno ha compilato PyQt4 su Snow Leopard con successo?

Answer 1

Ho appena fatto funzionare PyQt 4.6.2 con Python 2.6.1 a 64 bit. Ho pubblicato le istruzioni qui: http: / /mpastell.com/2009/11/24/pyqt-4-6-2-with-snow-leopard/

Answer 2

Nei log delle modifiche vedo Phil (manutentore di PyQt) ha rilasciato correzioni ieri nelle istantanee di sviluppo specifiche per Snow Leopard:

  

2009/09/14 12:12:49 phil Inoltre   correzioni per Snow Leopard a 64 bit   sistemi. aggiunto   QObject.pyqtConfigure ().

Stai usando la build di PyQt di ieri?

Questa discussione sulla mailinglist è anche particolarmente interessante.

I problemi di compilazione di PyQt sembrano essere causati dalle compilazioni predefinite a 64 bit di Snow Leopards e dalla versione mista a 64/32 bit di Python con cui viene fornita.

Se le cose continuano a andare male, vorrei inviare i tuoi problemi a questa mailing list (in modo che possano essere risolti - si spera) e provare a (temporaneamente) ricostruire Qt e PyQt (e possibilmente python) in modo a 32 bit (con il flag del compilatore -m32) se ne hai bisogno che funzioni ora.

Answer 3

Potresti voler usare PyQt dal progetto homebrew: build semplice, dipendenze gestite.

Funziona bene sul mio MBP Unibody, tutto a 64 bit.
