Slackware64 e applicazioni a 32 bit

[JohnnyMnemonic]

Salve, come da titolo volevo sapere tra quelli che stanno provando la nuova current a 64 bit come si stanno regolando per le applicazioni a 32 bit di cui non si dispone dei sorgenti (ad esempio Skype)

[Blizzard]

Questa discussione mi interessa, dato che ho scaricato la current e domani intendo cominciare a testarla per migrarci definitivamente all'uscita della 13.

Se il problema effettivamente esiste si potrebbe dedicare un thread all'elenco delle applicazioni che non sarà possibile lanciare nell'ambiente a 64 bit?

Del tipo in un thread si parlava di wine perchè non riesce ad emulare su processori 64 ecc...

Ciao
Gio

Non so se su slackware vada bene lo stesso, o se si può prendere come spunto.
Su debian amd_64 si possono far girare i programmi a 32 con chroot:

se è utile bene, altrimenti fate finta che non abbia postato nulla

Come suggerito da Conraid in altro luogo c'è anche questo metodo

http://www.slackware.org.uk/slamd64/sla ... 4-current/

Ma si tratta di cambiare molti pacchetti...

[neongen]

io sto usando i pacchetti di compatibilità di bluewhite

in realta' sono aggiuntivi (striminziti, praticamente solo librerie), non sono invasivi, buttano praticamente tutto in /usr/lib: ho dato un'occhiata agli slackbuilds e in pratica cancellano tutto quello che non e' in $PKG/usr/lib prima del makepkg.
io li uso senza problemi per wine e enemy territory: devo ancora spiegarmi perche', ma i giochi vanno piu' veloci cosi' che su una slackware a 32bit pulita (con la solita versione dei driver nvidia -l'ultima stabile, 185.18.14- c'e' un aumento molto sensibile di prestazioni)

[NikyBiasion]

Ponce, puoi posta re lo slackbuild di wine che hai usato o spiegare come hai fatto?
Io credo di avere dei problemi con le opengl, wine compila e mi funziona, ma se faccio partire un gioco (wow) non si avvia la parte grafica e il processo rimane bloccato a 99% della cpu.

lo slackbuild che ho usato e' questo

mah, niente da fare. Nemmeno con il tuo slackbuild funziona. E come con il mio, la prima volta che lancio winecfg (quindi senza aver la directory ~/.wine) mi da errore. O è un problema della 1.1.25 o sono le librerie di compatibilità, in ambiente chroot funziona perfettamente.

[ponce]

potrebbe dipendere dalla versione di mesa installata (che viene usata per compilare wine): con le nvidia penso vengano usate le librerie opengl proprietarie
darei un'occhiata anche qui, magari dicono qualcosa di pertinente...

[NikyBiasion]

Risolto! Reinstallando i dirver NVidia mi ha ripristinato alcune librerie di compatibilità!

[targzeta]

Per far girare un programma compilato a 32 bit sul sistema operativo a 64 bit bisogna abilitare l'emulazione a 32 bit. Il parametro si chiama

Codice: Seleziona tutto

CONFIG_IA32_EMULATION=y

ma forse di default è già attivo nel kernel della slackware a 64 bit.

Una volta che il kernel è capace di eseguire programmi a 32bit, allora basta avere le librerie a 32 bit richieste dal programma e il gioco è fatto.

Suddette librerie le potete prendere o dai pacchetti slackware (cercando di evitare l'installazione dei binari) oppure più semplicemente dai pacchetti per la slamd64 che ha una directory chiamata /c (ad esempio eccovi un mirror) contenente molte librerie a 32 bit.
