I am using xcode5 building a iOS static library which support arm64 for iphone5s, but when building the assembly file, It shows the error message as below.

/Users/markchen/iDev/webRTC/ios/svnWebRTC/webrtcLibSource/trunk/webrtc/common_audio/signal_processing/complex_bit_reverse_arm.S:1:1: error: unexpected token at start of statement

我认为您正在尝试构建类似的东西

? 首先，这是 arm64 汇编程序将拒绝为无效的 armv7 程序集。但是您看到的错误是因为@用于在此文件中标记注释的字符无法被 iOS 的 arm64 汇编程序识别。您确定此文件在传递给汇编程序之前不应该进行预处理吗？或者它可能是为不同的汇编程序编写的。
