I'm trying to compile Opus 1.1-rc2 with ARM NEON optimizations for iOS.

Here is the configure that I am using :

export CC="xcrun -sdk iphoneos clang -arch armv7"
export CCAS="xcrun -sdk iphoneos clang -arch armv7 -no-integrated-as"
./configure --enable-fixed-point \
            --disable-doc \
            --disable-extra-programs \
            --with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk \
            --host=arm-apple-darwin

If I use --disable-asm, everything compiles gloriously :) But I do want the ARM NEON optimizations, so I don't want to put the flag. And here come the troubles :

Without -no-integrated-as, I get:

clang: error: assembler command failed with exit code 1 (use -v to see invocation)

So what should I do to compile Opus with ASM NEON optimizations for iOS ?

(BTW, compiling Opus with ASM Neon optims for Android was very easy and straightforward)

도움이 되었습니까?

해결책

There are known build issues with the new Neon assembly. For now, the best thing to do in case of problem is to configure with --disable-rtcd.

다른 팁

Looking at the non-integrated assembly errors (and the -gnu filename), I'd say this was written for gas rather than llvm, which is why you're probably compiling fine for Android (you're probably using gas there, aren't you?)

I'd recommend trying the gas-preprocessor.pl script to convert this code first. It's designed to convert the ffmpeg code to work with Apple's old gas assembler, so it will probably get it closer to where you need for LLVM. You may still need to go through and lowercase the instructions, though.

You could also try compiling this with GCC into a static library. You could also google for "opus ios." It looks like others have attacked this problem (not sure if that script actually works for this, but it's a start).
