1. Download and install the iPhone SDK 3.1. how to install? you need to open folders in usr dir called local and then bin then in bin put gas-preprocessor.pl file. then try the configure command. Note: by default usr dir which is in root level is hidden, you need to right click on finder icon, select "Go to Folder" then type /usr and enter to reveal usr directory.
文本编辑器打开configure文件， 根据需要修改 ./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-avdevice --disable-avcore --disable-avformat --disable-swscale --disable-decoders --enable-cross-compile --arch=arm --target-os=darwin --cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7' --enable-pic 4b. For other iPhone or iPod Touch models, use this command: 注：路径名有空格编译会出错 It is important to specify a correct –cpu option, and not merely an architecture version. Failure to specify the exact CPU will give a broken build. For the iPhone 3GS and compatible iPods, –enable-pic is required to avoid some nasty-looking linker warnings about relocations. I have not tested the builds on an iPhone/iPod, so there may still be remaining issues. Please report any problems you encounter. Many thanks to David Conrad for the gas-preprocessor script, without which this would not be possible. 参考资料： 转自：http://blog.csdn.net/tozheng/archive/2010/11/10/6000974.aspx (tozheng) |
