Error in building MobileVLCKit

I'm trying to build MobileVLC on OS X Leopard, using iOS SDK 4.3.

Followed the given instructions, however, build stops and fails here: [info] Building contrib for iOS in '/Users/matp/MobileVLC/ImportedSources/vlc/contrib-builddir-ios-arm-apple-darwin10'

Current log:./buildMobileVLC.sh 
[info] Preparing build dirs
[info] Building

[info] Building libvlc for the iOS
[info] Using armv7 with SDK version 4.3
[info] Building contrib for iOS in '/Users/matp/MobileVLC/ImportedSourc开发者_如何学Goes/vlc/contrib-builddir-ios-arm-apple-darwin10'

The error is given as follows:

make[1]: *** [.ffmpeg] Error 1
make: *** [using-src] Error 2
/ImportedSources/vlc/contrib-builddir-ios-arm-apple-darwin10/build-src/ffmpeg/config.log tells me:

ld: warning: directory not found for option '-L/Users/matp/MobileVLC/ImportedSources/vlc/contrib-ios-arm-apple-darwin10/lib'
ld: warning: directory not found for option '-L/Users/matp/MobileVLC/ImportedSources/vlc/contrib-ios-arm-apple-darwin10/lib'
ld: file not found: /usr/lib/system/libcache.dylib for architecture armv7
collect2: ld returned 1 exit status
C compiler test failed.

Also before changing in order to get this far with the sdk 4.3 I had to change the sdk in buildMobileVLC.sh to 4.3 from 4.2. Before the change I got the error:

xcodebuild: error: SDK "iphoneos4.2" cannot be located.

How do I fix this error? and can fixing the xcodebuild error in a different way fix both of the problems?

Edit: ImportedSources/vlc/extras/contrib/bootstrap

Add: EXTRA_LDFLAGS="${EXTRA_LDFLAGS} -isysroot ${IOS_SDK_ROOT}"

Before:

if test -z "$IOS_SDK_ROOT"; then error "The bootstrap script requires the IOS_SDK_ROOT environment " error "variable to be set when building for iOS" exit 1 fi

two method: 1. you’d better install iOS SDK 4.2 from package Xcode 3.2.5／3.26

1. edit your script, ./MobileVLC/build_for_iOS.sh , change 4.2 -> 4.3

after that you might go further
