Проблема компиляции libav в iPhone SDK 4.3

/ 01 апреля 2011

Я столкнулся со странной проблемой. Я установил iPhone SDK 4.3 и xCode 4 и теперь не могу скомпилировать libav из ffmpeg для архитектуры ARMv6. Это мой скрипт для его компиляции (он отлично работает для iPhone SDK 4.2): 

./configure \
--disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile \
--enable-encoder=rawvideo \
--enable-decoder=h264 \
--enable-decoder=mpeg4 \
--enable-encoder=mjpeg \
--enable-muxer=rawvideo \
--enable-demuxer=h264 \
--enable-parser=h264 \
--enable-cross-compile \
--arch=c \
--target-os=darwin \
--enable-libopencore-amrnb --enable-libopencore-amrwb \
--cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 \
--as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer    /usr/bin/arm-apple-darwin10-gcc-4.2.1' \
--sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk \
--cpu=arm1176jzf-s --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6'

make clean
make

в результате я получаю библиотечные файлы, но когда я проверяю их с помощью команды lipo -info, это показывает, что библиотека была скомпилирована для архитектуры i386.

Может, кто-нибудь сталкивался с такой проблемой? Помогите мне, пожалуйста.

Спасибо.

Вот обновленный скрипт, который удаляет armv6, добавляет armv7s, использует iOS 6.0 SDK и исправляет проблемы с изменениями в инструменте lipo.Убедитесь, что у вас установлена ​​последняя версия gas-preprocessor.pl из github в /usr/local/bin:

Это создаст статическую ffmpegбиблиотеки для архитектур armv6, armv7 и i386 и объединение их в толстые (универсальные) файлы для iOS 4.3 (iPhoneOS4.3 и iPhoneSimulator4.3):
