我试图编译LIVE555为iOS。
我也做了以下情况：
./genMakefiles iphoneos
make
我得到以下编译错误：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++ -c -I../UsageEnvironment/include -I../groupsock/include -I../liveMedia/include -I../BasicUsageEnvironment/include -I. -DBSD=1 -O2 -DSOCKLEN_T=socklen_t -DHAVE_SOCKADDR_LEN=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -fPIC -arch armv7 --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk -Wall testMP3Streamer.cpp

我试图改变以及在config.iphoneos连接选项，以这样的：
LINK_OPTS = -L. -arch armv7 --isysroot=$(SDK)
当我改变了链接选项我得到了以下错误：
cd testProgs ; make

任何想法，我做错了什么？
