Xcode4.5 assemblatore non riesce a compilare i file che Xcode4.4 manipolato perfettamente

Question

Dopo l'aggiornamento Xcode 4.5 per la versione che ho un errore

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

ho letto di errore come questo dopo l'aggiornamento, ma cambiando l'architettura in target di costruisce le impostazioni non aiutano. Funziona sul simulatore ma non sul dispositivo.

L'intero errore

Ho un errore come questo prima, quando ho dimenticato aggiungere libz.dylib in fasi di creazione. Hai qualche idea su come risolverlo?

Grazie mille,

Answer 1

Sì, Xcode 4.5 ha apportato alcune modifiche che rompono compilazione del codice ASM. La soluzione è semplice, basta aggiungere il flag -no-integrated-as alle opzioni di compilazione per il file maxvid_decode_arm.s in AVAnimator.

Come così:

scegliere il file di progetto nella finestra di sinistra che elenca i file (è quello in alto con l'icona blu).

Seleziona il tuo Target nell'elenco "TARGET".

Selezionare la scheda "Fasi di creazione".

Fare doppio clic su maxvid_decode_arm.s, quindi aggiungere -no-integrato-come incollando l'elenco che viene visualizzato.

Answer 2

L'errore è del tutto evidente - due istruzioni assembler in max_vid_decode.s non siano adeguatamente formattati:

strneh r8, [r10], #2 
stmeqia r10!, {r0, r1} 

Probabilmente la spec assemblatore ha stretto, e codice che è stato un po 'non -compliant ha funzionato in precedenza. Trova il documento assembler armv7 e leggi questi due comandi e rendili compatibili.

Answer 3

Trovato questo in Workflow for writing ARM assembly code on the iphone. In realtà penso che i'ts lo sviluppatore che ha risposto è

add -no-integrated-as in your compiler flags in buildphases.
