** BUILD FAILED ** with ios 5.1

[sharp]

Hi kolyvan , I modify the rakefile for ios5.1 and run rake

** BUILD FAILED **


The following build commands failed:

Sorry, but I can't help you.
Too little information from you about failure.
By the way, No need to change rakefile for support of ios 5.1.
You can compile kxmovie with help a current rakefile with ios 6.0 SDK and then run without problem on device with ios 5.1.
If for some reason, you must use 5.1 SDK, then you must replace all references of 6.0 SDK to 5.1:
Like replace 'iPhoneSimulator6.0.sdk' to 'iPhoneSimulator5.1.sdk' and so on.

It seems what you used old xcode for build.
From version 4.4 xcode includes an update llvm compiler 4.0.
It's objective-c literals: @{}, @[] for collections and @() for boxing C expressions.
Also @properties are synthesized by default.
So these errors due to a lack of new features of llvm 4.0.
